Fix crash when setting breakpoint condition
gdb could crash when setting a breakpoint condition on a breakpoint
when using the Ada language. The problem occurred because the
ada_evaluate_subexp would try to evaluate the array to compute its
attributes, but evaluating can't really be done at this time.
This patch fixes the problem by arranging not to try to evaluate in
EVAL_AVOID_SIDE_EFFECTS mode when computing an attribute.
Tested on x86-64 Fedora 29. Because this is Ada-specific, and because
Joel approved it internally, I am checking it in.

Instantiate a single source highlighter
It occurred to me that there's no reason to make a new source
highlighter each time gdb needs to highlight some source code.
Instead, a single one can be created and then simply reused each time.
This patch implements this idea. Tested on x86-64 Fedora 29.

PowerPC64 notoc calls
Calls from functions that don't have a valid toc pointer in r2 (these
calls are marked with _NOTOC relocs) to functions that require r2
valid must go via the callee global entry point. This patch corrects
the condition the linker was using to detect functions that require r2
to be valid. Values of both zero and one in st_other local entry bits
mean a function doesn't care about r2.
* elf64-ppc.c (ppc64_elf_inline_plt): Correct st_other test for
functions that require r2 valid to use local entry.
(ppc64_elf_size_stubs, ppc64_elf_relocate_section): Likewise.

gdb: Remove use of deprecated_interactive_hook
The deprecated_interactive_hook is not used within GDB. It is used in
gdbtk, however this patch removes that use:
https://sourceware.org/ml/insight/2019-q2/msg00001.html
So I think there is no longer a reason to keep this hook around.
This patch removes it. There should be no user visible changes after
this commit.
gdb/ChangeLog:
* defs.h (deprecated_interactive_hook): Delete declaration.
* interps.c (clear_interpreter_hooks): Remove use of
deprecated_interactive_hook.
* top.c (deprecated_interactive_hook): Delete definition.
* utils.c (maybe_quit): Remove use of deprecated_interactive_hook.

[gdb/testsuite] Use -fuse-ld=gold in fission.exp
The target board fission.exp requires the gold linker (because it supports
--gdb-index).
When running the target board on a system where the default linker is not
gold, most tests will fail to compile.
Fix this by adding "-fuse-ld=gold" ( supported in gcc since version 4.8).

2019-06-18 Tom de Vries <tdevries@suse.de>
* boards/fission.exp (debug_flags): Add "-fuse-ld=gold".

[gdb] Fix abstract_to_concrete type
The test-case varval.exp fails here:
...
FAIL: gdb.dwarf2/varval.exp: print varval2
...
with boards readnow/cc-with-gdb-index/cc-with-debug-names, as well as if gdb
is build with -fsanitize=address -lasan.
The problem is that the abstract_to_concrete map in which we track the
association of abstract to concrete DIEs (for DW_OP_GNU_variable_value
support) has type std::unordered_map<die_info_ptr, std::vector<die_info_ptr>>,
and the die_info_ptrs that we register in the map may be invalid by the time
that we start to lookup DIEs in the map.
Fix this by using the sect_offset instead to identify the DIEs in the map.
Build and tested on x86_64-linux.

doc: fix false claim about second argument to gdb
Section "Invoking GDB" of the manual states that if you try to launch
gdb with:
gdb program 1234
it will try to attach to the process with id 1234, unless there is a
file named 1234 in the current working directory, in which case it will
try to open that file as a core. In fact, when the second argument
starts with a digit, GDB tries to attach to process 1234 first, before
trying to open file 1234 as a core. So that last remark is not true and
therefore this patch removes it.
The same remark is present in the man page, so it is removed there too.
Section "Choosing Files" correctly states:
If the second argument begins with a decimal digit, GDB will first
attempt to attach to it as a process, and if that fails, attempt to
open it as a corefile.
so it is unchanged.
Finally, the man page has an additional detail compared to section
"Invoking GDB", regarding the use of the -p switch, so I added the same
detail to the "Invoking GDB" section.
gdb/doc/ChangeLog:
* gdb.texinfo (Invoking GDB): Remove sentence about how GDB
deals with a file that has the same name as the specified pid to
attach to. Add example using -p option.
(gdb man): Remove same sentence as in previous item.

==3997==ABORTING
...
The direct cause is that child_path gets called with parent == "", so this
test:
...
if (IS_DIR_SEPARATOR (parent[parent_len - 1]))
...
accesses parent[-1].
[ There is an open discussion (1) about whether an empty sysroot should indeed
be represented internally as "". But this patch focuses on fixing the
heap-buffer-overflow without any redesign. ]
Fix this by guarding the test with 'parent_len > 0'.
Note that the fix makes child_path behave the same for:
- parent == "/" && child == "/foo" (returns "foo")
- parent == "" and child == "/foo" (returns "foo").
Build and reg-tested on x86_64-linux.

Don't cast a tui_win_info directly to tui_gen_win_info
I found a few spots that directly cast a tui_win_info to a
tui_gen_win_info. However, I think it's a bit better here to take the
address of the "generic" member. As far as I know, nothing relies on
being able to downcast here, so this gives us the freedom to rearrange

Write index for dwz -m file
PR 24445 ("dwz multifile index not written to index cache") exposed the
fact that we are not doing things right when we generate an index for an
object file that has is linked to a dwz file. The same happens whether
the index is generated with the intent of populating the index cache or
using the save gdb-index command.
The problem can be observed when running these tests with the
cc-with-dwz-m board:
FAIL: gdb.base/index-cache.exp: test_cache_enabled_hit: check index-cache stats
FAIL: gdb.dwarf2/gdb-index.exp: index used
FAIL: gdb.dwarf2/gdb-index.exp: index used after symbol reloading
When generating the index for such file and inspecting the CU list of the
resulting index (with readelf --debug-dump=gdb_index), we can see something
like:
CU table:
[ 0] 0x0 - 0xb9
[ 1] 0x0 - 0x44
This is supposed to be a sorted list of the ranges of all CUs in the
file this index represents, so already having some overlap is a red
flag. It turns out that we save the ranges of CUs coming from both the
main file and the dwz file in the same index.
After digging a little bit, it became quite obvious that the index in
the main file should only list the CUs present in the main file, and a
separate index should be generated for the dwz file, listing the CUs
present in that file.
First, that's what happens if you run dwz on a file that already has a
GDB index embedded. Second, dwarf2read.c has code to read an index from
a dwz file. The index in the dwz file is actually required to be
present, if the main file has an index.
So this patch changes write_psymtabs_to_index to generate an index for
the dwz file, if present. That index only contains a CU list, just like
what the dwz tool does when processing a file that already contains an
index.
Some notes about the implementation:
- The file management (creating a temp file, make sure it's
close/removed on error - in the right order) is a bit heavy in
write_psymtabs_to_index, and I needed to add a third file. I factored
this pattern in a separate class, index_wip_file.
- It became a bit tedious to keep the call to assert_file_size in
write_psymtabs_to_index, write_gdbindex would have had to return two
sizes. Instead, I moved the calls to assert_file_size where the file
is written. The downside is that we lose the filename at this point,
but it was only used for the very improbable case of ftell failing, so
I think it's not a problem.
- The actual writing of the index file is factored out to
write_gdbindex_1, so it can be re-used for both index files.
- While the "save gdb-index" command will now write two .gdb-index
files, this patch does not update the gdb-add-index.sh script, this
will come in a later patch.

The problem is similar to what was fixed in
5a56d6a65f84 ("[gdb/testsuite] Fix index-cache.exp with cc-with-{gdb-index,debug-names}")
In that commit, gdb.base/index-cache.exp was modified to account for the
fact that the index cache is not used when the binary already has an
embedded index.
The same situation happens when GDB is started with the -readnow flag:
it bypasses indices and partial symbols. So this patch updates the test
to also expect the index cache not to be used if -readnow is present in
$GDBFLAGS,

The type of 'vla' is now printed correctly, while the value itself
still shows as '<not allocated>'. How GDB prints the type of
associated pointers has changed in a similar way.

gdb/mi: New commands to catch C++ exceptions
Adds some MI commands to catch C++ exceptions. The new commands are
-catch-throw, -catch-rethrow, and -catch-catch, these all correspond
to the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'.
Each MI command takes two optional arguments, '-t' has the effect of
calling 'tcatch' instead of 'catch', for example:
(gdb)
-catch-throw -t
Is the same as:
(gdb) tcatch throw
There is also a '-r REGEXP' argument that can supply a regexp to match
against the exception type, so:
(gdb)
-catch-catch -r PATTERN
Is the same as:
(gdb) catch catch PATTERN
The change in print_mention_exception_catchpoint might seem a little
strange; changing the output from using ui_out::field_int and
ui_out::text to using ui_out::message.
The print_mention_exception_catchpoint is used as the 'print_mention'
method for the exception catchpoint breakpoint object. Most of the
other 'print_mention' methods (see breakpoint.c) use either
printf_filtered, of ui_out::message. Using field_int was causing an
unexpected field to be added to the MI output. Here's the output
without the change in print_mention_exception_catchpoint:
(gdb)
-catch-throw
^done,bkptno="1",bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",addr="0x00000000004006c0",
what="exception throw",catch-type="throw",
thread-groups=["i1"],times="0"}
Notice the breakpoint number appears in both the 'bkptno' field, and
the 'number' field within the 'bkpt' tuple. Here's the output with
the change in print_mention_exception_catchpoint:
(gdb)
-catch-throw
^done,bkpt={number="1",type="breakpoint",disp="keep",
enabled="y",addr="0x00000000004006c0",

gdb: Don't allow annotations to influence what else GDB prints
The annotations should be additional information printed by GDB to be
consumed by users (GUIs), but GDB shouldn't reduce what it prints
based on whether annotations are on or not. However, this is what
happens for annotate_source_line.
This commit makes annotate_source_line a void function that simply
outputs the annotation information, GDB will then print the contents
of the source line to the terminal in the normal way.
Some tests needed to be updated after this commit.

* annotate.c (annotate_source_line): Change return type to void,
update implementation to match.

gdb: Remove an update of current_source_line and current_source_symtab
While reviewing some of the annotation code I noticed that
identify_source_line (in source.c) sets current_source_line,
current_source_symtab, and also calls clear_lines_listed_range. This
seems a little strange, identify_source_line is really a wrapper
around annotate_source, and is only called when annotation_level is
greater than 0 (so annotations are turned on).
It seems weird (to me) that when annotations are on we update GDB's
idea of the "current" line/symtab, but when they are off we don't,
given that annotations are really about communicating GDB's state to a
user (GUI) and surely shouldn't be changing GDB's behaviour.
This commit removes from identify_source_line all of the setting of
current line/symtab and the call to clear_lines_listed_range, after
doing this GDB still passes all tests, so I don't believe these lines
were actually required.
With this code removed identify_source_line is only a wrapper around
annotate_source, so I moved identify_source_line to annotate.c and
renamed it to annotate_source_line.
gdb/ChangeLog:
* annotate.c: Add 'source.h' and 'objfiles.h' includes.
(annotate_source): Make static.
(annotate_source_line): Moved from source.c and renamed from
identify_source_line. Update the return type.
* annotate.h (annotate_source): Delete declaration.
(annotate_source_line): Declaration moved from source.h, and
renamed from identify_source_line. Return type updated.
* source.c (identify_source_line): Moved to annotate.c and renamed
to annotate_source_line.
(info_line_command): Remove check of annotation_level.
* source.h (identify_source_line): Move declaration to annotate.h
and rename to annotate_source_line.
* stack.c: Add 'annotate.h' include.
(print_frame_info): Remove check of annotation_level before
calling annotate_source_line.

Move gnulib to top level
This patch moves the gdb/gnulib subdirectory to the top level.
It adjusts the top-level build system to build gnulib when necessary,
and changes gdb to use this. However, gdbserver still builds its own
copy of gnulib, just from the new source location.
A small hack was needed to ensure that gnulib is only built when gdb
is enabled. The Makefile only provides an ordering -- the directory
must be mentioned in configdirs to actually be compiled at all.
Most of the patch is just a "git mv" of gnulib, though a few minor
path adjustments were needed in some files there.
Tested by the buildbot.

Only compute realpath when basenames_may_differ is set
A user noted that, when sources are symlinked, gdb annotations will
print the real path, rather than the name of the symlink.
It seems to me that it is better to print the name of the file that
was actually used in the build, unless there is some reason not to.
This patch implements this, with the caveat that it will not work when
basenames-may-differ is enabled. The way this mode is currently
implemented, returning the symbolic (not real) path is not possible.
While I think it would be good to redo the source file name cache and
perhaps integrate it with class source_cache, I haven't done so here.

Fix gdb build with -std=gnu++11
The options framework series broken the build with gcc 4.8, or any
other compiler were we end up forcing -std=gnu++11, causing errors
like these:
../../binutils-gdb/gdb/compile/compile.c: In function gdb::option::option_def_group make_compile_options_def_group(compile_options*):
../../binutils-gdb/gdb/compile/compile.c:266:44: error: could not convert (const gdb::option::option_def*)(& compile_command_option_defs) from const gdb::option::option_def* to gdb::array_view<const gdb::option::option_def>
return {compile_command_option_defs, opts};
^
CXX copying.o
../../binutils-gdb/gdb/compile/compile.c:267:1: error: control reaches end of non-void function [-Werror=return-type]
}
^
This is a C++11 vs C++14 difference -- C++14 relaxed the rules for
eliding braces.
This commit fixes it by adding the missing (in C++11) braces. Tested
with g++ 4.8.

Delete parse_flags/parse_flags_qcs
Now that "thread/frame apply" have been converted to the gdb::option
framework, these functions are no longer used.
For a while, I thought about keeping the unit tests, by making a local
version of parse_flags_qcs in the unit tests file. But all that would
really test that is used by GDB itself, is the validate_flags_qcs
function. So in the end, I went through all the unit tests, and
converted any that wasn't already covered to gdb.base/options.exp
tests. And those have all already been added in previous patches.

Make "thread apply" use the gdb::option framework
Similarly to the "frame apply" patch, this makes the "thread apply"
family of commands -- "thread apply TID", "thread apply all" and
"taas" use the gdb::option framework for '-'-style options.
No new options are added, but there are some user-visible changes:
- Can now abbreviate and complete "-ascending"
- We now have a completer for "thread apply" commands
Can now complete options ("thread apply all -[TAB]"), and also,
'thread apply all COMMAND[TAB]' now does what you'd expect, by
making use of the new complete_command routine.
- "help" output tweaked with auto-generated option descriptions:
~~~
Usage: thread apply all [OPTION]... COMMAND
Prints per-inferior thread number and target system's thread id
followed by COMMAND output.
By default, an error raised during the execution of COMMAND
aborts "thread apply".
Options:
-ascending
Call COMMAND for all threads in ascending order.
The default is descending order.
-q
Disables printing the thread information.
-c
Print any error raised by COMMAND and continue.
-s
Silently ignore any errors or empty output produced by COMMAND.
~~~
The "By default ..." sentence is new as well.

"thread apply 1 -- -" vs "frame apply level 0 -- -"
With the following patch, we'll be able to explicitly tell "thread
apply" where options end, using the "--" delimiter. A test added by
that patch caught a pre-existing inconsistency:
(gdb) thread apply 1 -- -
Invalid thread ID: -
(gdb) frame apply level 0 -- -
#0 main () at threads.c:55
Cannot enable the TUI when output is not a terminal
Above, "thread apply" did not try to run the command, while "frame
apply level" did. ("-" is a valid TUI command.)
That "-" is past "--", so it should have not been confused with an
invalid TID, in the "thread apply" case.
That error actually doesn't come from the TID parser, but instead from
thread_apply_command directly.
So that error/check needs tweaking. The next question is what to
tweak it to.
"-" is actually a valid TUI command:
(gdb) help -
Scroll window backward.
Usage: - [WIN] [N]
(gdb) frame apply level 0 -- -
#0 main () at threads.c:55
Cannot enable the TUI when output is not a terminal
While I don't imagine it being useful to use that "-" command with
"thread apply" or "frame apply level", the fact is that you can use it
with "frame apply level", but not with "thread apply". And since it's
an actual command, pedantically it seems right to allow it.
That's what this commit does.
Note: simply removing the "isalpha" check regresses

Make "frame apply" support -OPT options
This adds support for '-'-style options to the "frame apply" family of
commands -- "frame apply COUNT", "frame apply level", "frame apply
all", "faas" and "tfaas".
The -q/-c/-s flags were already supported, -past-main/-past-entry is
new:
~~~
(gdb) help frame apply all
Apply a command to all frames.
Usage: frame apply all [OPTION]... COMMAND
Prints the frame location information followed by COMMAND output.
By default, an error raised during the execution of COMMAND
aborts "frame apply".
Options:
-q
Disables printing the frame location information.
-c
Print any error raised by COMMAND and continue.
-s
Silently ignore any errors or empty output produced by COMMAND.
-past-main [on|off]
Set whether backtraces should continue past "main".
Normally the caller of "main" is not of interest, so GDB will terminate
the backtrace at "main". Set this if you need to see the rest
of the stack trace.
-past-entry [on|off]
Set whether backtraces should continue past the entry point of a program.
Normally there are no callers beyond the entry point of a program, so GDB
will terminate the backtrace there. Set this if you need to see
the rest of the stack trace.
~~~
TAB completion of options is now supported. Also, TAB completion of
COMMAND in "frame apply all COMMAND" does the right thing now, making
use of complete_command, added by the previous patch. E.g.:
(gdb) thread apply all -ascending frame apply all -past-main print -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
(gdb) thread apply all -ascending frame apply all -past-main print glo[TAB]
global1 global2
The change to tfaas_command is necessary because otherwise you get
this:
(gdb) tfaas --
Unrecognized option at: frame apply all -s --
That's because the above is equivalent to:
(gdb) thread apply all -s frame apply all -s --
and the "--" instructs "thread apply" to consider everything up to
"--" as its command options. And from that view, "frame" is an
invalid option.
The change makes tfaas be equivalent to:
(gdb) thread apply all -s -- frame apply all -s --

Introduce complete_nested_command_line
This adds a completion helper routine that makes it possible for a
command that takes another command as argument, such as "frame apply
all COMMAND" as "thread apply all COMMAND", to complete on COMMAND,
and have the completion machinery recurse and complete COMMAND as if
you tried to complete "(gdb) COMMAND". I.e., we'll be able to
complete like this, for example:
(gdb) thread apply all -[TAB]
-c -ascending -q -s
(gdb) thread apply all -ascending frame apply all -[TAB]
-c -limit -past-entry -past-main -q -s
(gdb) thread apply all -ascending frame apply all -past-main print -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
(gdb) thread apply all -ascending frame apply all -past-main print glo[TAB]
global1 global2
Above, the completer function understands that "thread apply all" is a
command, and then parses "-ascending" successfully and understand that
the rest of the string is "thread apply all"'s operand. And then, the
process repeats for the "frame apply" command, and on and on.

"backtrace full/no-filters/hide" completer
"backtrace"'s completer now completes on command options:
(gdb) bt -[TAB]
-entry-values -full -no-filters -past-main
-frame-arguments -hide -past-entry -raw-frame-arguments
But it doesn't know how to complete on qualifiers:
(gdb) bt fu[TAB]
funlockfile futimens futimes.c
funlockfile.c futimens.c futimesat
futex-internal.h futimes futimesat.c
This commit fixes that:
(gdb) bt fu[TAB]ll
(gdb) bt n[TAB]o-filters
(gdb) bt h[TAB]ide
I considered teaching the gdb::option framework to handle non-'-'
options, but decided it wasn't worth it for this special case, and I'd
rather not make it easy to add new qualifier-like options.

Make "backtrace" support -OPT options
This adds support for comand options to the "backtrace" command. We'll get:
(gdb) bt -
-entry-values -hide -past-main
-frame-arguments -no-filters -raw-frame-arguments
-full -past-entry
~~~~
(gdb) help backtrace
Print backtrace of all stack frames, or innermost COUNT frames.
Usage: backtrace [OPTION]... [QUALIFIER]... [COUNT | -COUNT]
Options:
-entry-values no|only|preferred|if-needed|both|compact|default
Set printing of function arguments at function entry
GDB can sometimes determine the values of function arguments at entry,
in addition to their current values. This option tells GDB whether
to print the current value, the value at entry (marked as val@entry),
or both. Note that one or both of these values may be <optimized out>.
-frame-arguments all|scalars|none
Set printing of non-scalar frame arguments
-raw-frame-arguments [on|off]
Set whether to print frame arguments in raw form.
If set, frame arguments are printed in raw form, bypassing any
pretty-printers for that value.
-past-main [on|off]
Set whether backtraces should continue past "main".
Normally the caller of "main" is not of interest, so GDB will terminate
the backtrace at "main". Set this if you need to see the rest
of the stack trace.
-past-entry [on|off]
Set whether backtraces should continue past the entry point of a program.
Normally there are no callers beyond the entry point of a program, so GDB
will terminate the backtrace there. Set this if you need to see
the rest of the stack trace.
-full
Print values of local variables.
-no-filters
Prohibit frame filters from executing on a backtrace.
-hide
Causes Python frame filter elided frames to not be printed.
For backward compatibility, the following qualifiers are supported:
full - same as -full option.
no-filters - same as -no-filters option.
hide - same as -hide.
With a negative COUNT, print outermost -COUNT frames.
~~~~
Implementation wise, this:
- Moves relevant options/settings globals to structures.
- Tweaks a number of functions to pass down references to such structures.
- Adds option_def structures describing the options/settings.
- Makes backtrace_command parse the options, with gdb::option::process_options.
- Tweaks "backtrace"'s help to describe the new options.
- Adds testcases.
Note that backtrace is a PROCESS_OPTIONS_UNKNOWN_IS_OPERAND command,
because of the "-COUNT" argument.
The COUNT/-COUNT argument is currently parsed as an expression. I
considered whether it would be prudent here to require "--", but
concluded that the risk of causing a significant breakage here is much
lower compared to "print", since printing the expression is not the
whole point of the "backtrace" command. Seems OK to me to require
typing "backtrace -past-main -- -p" if the user truly wants to refer
to the negative of a backtrace count stored in an inferior variable
called "p".

"set print raw frame-arguments" -> "set print raw-frame-arguments"
A following patch will introduce options for the "backtrace" command,
based on some "set print" and "set backtrace" settings. There's one
setting in particular that is a bit annoying if we want to describe
the backtrace options and the settings commands using the same data
structures:
"set print raw frame-arguments"
The problem is that space between "raw" and "frame-arguments".
Calling the option
"bt -raw frame-arguments"
would be odd. So I'm calling the option
"bt -raw-frame-arguments"
instead.
And for consistency, this patch renames the set/show commands to:
"set print raw-frame-arguments"
"show print raw-frame-arguments"
I.e., dash instead of space. The old commands are left in place, but
marked deprecated.
We need to adjust a couple testcases, because the relevant tests use
gdb_test_no_output and the old commands are no longer silent:
(gdb) set print raw frame-arguments on
Warning: command 'set print raw frame-arguments' is deprecated.
Use 'set print raw-frame-arguments'.

Migrate rest of compile commands to new options framework
As I was in the neighbourhood, I converted the other "compile"
subcommands to the new options framework too. Specifically, "compile
code" and "compile file".
The user-visible changes are:
- All abbreviations of "-raw" are accepted now, instead of just -r.
Obviously that means "-ra" is now accepted.
- Option completion now works.
- "compile file" did not have a completer yet, and now it knows to
complete on filenames.
- You couldn't use "compile file" with a file named "-something".
You can now, with "compile file -- -something".

Make "print" and "compile print" support -OPT options
This patch adds support for "print -option optval --", etc.
Likewise for "compile print".
We'll get:
~~~~~~
(gdb) help print
Print value of expression EXP.
Usage: print [[OPTION]... --] [/FMT] [EXP]
Options:
-address [on|off]
Set printing of addresses.
-array [on|off]
Set pretty formatting of arrays.
-array-indexes [on|off]
Set printing of array indexes.
-elements NUMBER|unlimited
Set limit on string chars or array elements to print.
"unlimited" causes there to be no limit.
-max-depth NUMBER|unlimited
Set maximum print depth for nested structures, unions and arrays.
When structures, unions, or arrays are nested beyond this depth then they
will be replaced with either '{...}' or '(...)' depending on the language.
Use "unlimited" to print the complete structure.
-null-stop [on|off]
Set printing of char arrays to stop at first null char.
-object [on|off]
Set printing of C++ virtual function tables.
-pretty [on|off]
Set pretty formatting of structures.
-repeats NUMBER|unlimited
Set threshold for repeated print elements.
"unlimited" causes all elements to be individually printed.
-static-members [on|off]
Set printing of C++ static members.
-symbol [on|off]
Set printing of symbol names when printing pointers.
-union [on|off]
Set printing of unions interior to structures.
-vtbl [on|off]
Set printing of C++ virtual function tables.
Note: because this command accepts arbitrary expressions, if you
specify any command option, you must use a double dash ("--")
to mark the end of option processing. E.g.: "print -o -- myobj".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I want to highlight the comment above about "--".
At first, I thought we could make the print command parse the options,
and if the option wasn't recognized, fallback to parsing as an
expression. Then, if the user wanted to disambiguate, he'd use the
"--" option delimiter. For example, if you had a variable called
"object" and you wanted to print its negative, you'd have to do:
(gdb) print -- -object
After getting that working, I saw that gdb.pascal/floats.exp
regressed, in these tests:
gdb_test "print -r" " = -1\\.2(499.*|5|500.*)"
gdb_test "print -(r)" " = -1.2(499.*|5|500.*)"
gdb_test "print -(r + s)" " = -3\\.4(499.*|5|500.*)"
It's the first one that I found most concerning. It regressed because
"-r" is the abbreviation of "-raw". I realized then that the behavior
change was a bit risker than I'd like, considering scripts, wrappers
around gdb, etc., and even user expectation. So instead, I made the
print command _require_ the "--" options delimiter if you want to
specify any option. So:
(gdb) print -r
is parsed as an expression, and
(gdb) print -r --
is parsed as an option.
I noticed that that's also what lldb's expr (the equivalent of print)
does to handle the same problem.
Going back the options themselves, note that:
- you can shorten option names, as long as unambiguous.
- For boolean options, 0/1 stand for off/on.
- For boolean options, "true" is implied.
So these are all equivalent:
(gdb) print -object on -static-members off -pretty on -- foo
(gdb) print -object -static-members off -pretty -- foo
(gdb) print -object -static-members 0 -pretty -- foo
(gdb) print -o -st 0 -p -- foo
TAB completion is fully supported:
(gdb) p -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
Note that the code is organized such that some of the options and the
"set/show" commands code is shared. In particular, the "print"
options and the corresponding "set print" commands are defined with
the same structures. The commands are installed with the
gdb::option::add_setshow_cmds_for_options function.

commit 9d0faba9f52b898f0be539bc4d6fbd084772259d

Introduce generic command options framework
This commit adds a generic command options framework, that makes it
easy enough to add '-'-style options to commands in a uniform way,
instead of each command implementing option parsing in its own way.
Options are defined in arrays of option_def objects (for option
definition), and the same options definitions are used for supporting
TAB completion, and also for generating the relevant help fragment of
the "help" command. See the gdb::options::build_help function, which
returns a string with the result of replacing %OPTIONS% in a template
string with an auto-generated "help" string fragment for all the
passed-in options.
Since most options in GDB are in the form of "-OPT", with a single
dash, this is the format that the framework supports.
I like to think of gdb's "-OPT" as the equivalent to getopt's long
options format ("--OPT"), and gdb's "/" as the equivalent to getopt's
short options format. getopt's short options format allows mixing
several one-character options, like "ls -als", kind of similar to
gdb's "x /FMT" and "disassemble /MOD", etc. While with gdb's "-"
options, the option is expected to have a full name, and to be
abbreviatable. E.g., "watch -location", "break -function main", etc.
This patch only deals with "-" options. The above comment serves more
to disclose why I don't think we should support mixing several
unrelated options in a single "-" option invocation, like "thread
apply -qcs" instead of "thread apply -q -c -s".
The following patches will add uses of the infrastructure to several
key commands. Most notably, "print", "compile print", "backtrace",
"frame apply" and "thread apply". I tried to add options to several
commands in order to make sure the framework didn't leave that many
open holes open.
Options use the same type as set commands -- enum var_types. So
boolean options are var_boolean, enum options are var_enum, etc. The
idea is to share code between settings commands and command options.
The "print" options will be based on the "set print" commands, and
their names will be the same. Actually, their definitions will be the
same too. There is a function to create "set/show" commands from an
array for option definitions:
/* Install set/show commands for options defined in OPTIONS. DATA is
a pointer to the structure that holds the data associated with the
OPTIONS array. */
extern void add_setshow_cmds_for_options (command_class cmd_class, void *data,
gdb::array_view<const option_def> options,
struct cmd_list_element **set_list,
struct cmd_list_element **show_list);
That will be used by several following patches.
Other features:
- You can use the "--" delimiter to explicitly indicate end of
options. Several existing commands use this token sequence for
this effect already, so this just standardizes it.
- You can shorten option names, as long as unambiguous. Currently,
some commands allow this (e.g., break -function), while others do
not (thread apply all -ascending). As GDB allows abbreviating
command names and other things, it feels more GDB-ish to allow
abbreviating option names too, to me.
- For boolean options, 0/1 stands for off/on, just like with boolean
"set" commands.
- For boolean options, "true" is implied, just like with boolean "set
commands.
These are the option types supported, with a few examples:
- boolean options (var_boolean). The option's argument is optional.
(gdb) print -pretty on -- *obj
(gdb) print -pretty off -- *obj
(gdb) print -p -- *obj
(gdb) print -p 0 -- *obj
- flag options (like var_boolean, but no option argument (on/off))
(gdb) thread apply all -s COMMAND
- enum options (var_enum)
(gdb) bt -entry-values compact
(gdb) bt -e c
- uinteger options (var_uinteger)
(gdb) print -elements 100 -- *obj
(gdb) print -e 100 -- *obj
(gdb) print -elements unlimited -- *obj
(gdb) print -e u -- *obj
- zuinteger-unlimited options (var_zuinteger_unlimited)
(gdb) print -max-depth 100 -- obj
(gdb) print -max-depth -1 -- obj
(gdb) print -max-depth unlimited -- obj
Other var_types could be supported, of course. These were just the
types that I needed for the commands that I ported over, in the
following patches.
It was interesting (and unfortunate) to find that we need at least 3
different modes to cover the existing commands:
- Commands that require ending options with "--" if you specify any
option: "print" and "compile print".
- Commands that do not want to require "--", and want to error out if
you specify an unknown option (i.e., an unknown argument that starts
with '-'): "compile code" / "compile file".
- Commands that do not want to require "--", and want to process
unknown options themselves: "bt", because of "bt -COUNT",
"thread/frame apply", because "-" is a valid command.
The different behavior is encoded in the process_options_mode enum,
passed to process_options/complete_options.
For testing, this patch adds one representative maintenance command
for each of the process_options_mode values, that are used by the
testsuite to exercise the options framework:
(gdb) maint test-options require-delimiter
(gdb) maint test-options unknown-is-error
(gdb) maint test-options unknown-is-operand
and adds another command to help with TAB-completion testing:
(gdb) maint show test-options-completion-result
See their description at the top of the maint-test-options.c file.
Docs/NEWS are in a patch later in the series.

number_or_range_parser::get_number, don't treat "1 -" as a range
While adding -OPT options to "frame apply level", I noticed that:
(gdb) frame apply level 0 -[TAB]
wasn't completing on the supported options. This commit fixes it.
We'll get instead:
(gdb) frame apply level 0 -
-c -past-entry -past-main -q -s
I added the isspace check because this case:
(gdb) frame apply level 0-
can't be an option.
Tests for this will be in a new gdb.base/options.exp file, in a

boolean/auto-boolean commands, make "o" ambiguous
We currently accept "o" with boolean/auto-boolean commands, taking it
to mean "on". But "o" is ambiguous, between "on" and "off". I can't
imagine why assuming the user wanted to type "on" is a good idea, it
might have been a typo.
This commit makes gdb error out. We now get:

"on" or "off" expected.

"on", "off" or "auto" expected.

New set/show testing framework (gdb.base/settings.exp)
This commit adds new representative commands for all types of settings
commands supported by gdb (enum var_types), and then uses them to
exercise settings parsing and completion.
(gdb) maint test-settings s[TAB]
set show
(gdb) maint test-settings set [TAB]
auto-boolean integer uinteger
boolean optional-filename zinteger
enum string zuinteger
filename string-noescape zuinteger-unlimited
(gdb) maint test-settings set enum [TAB]

Remove "show" command completers, "set" command completers for string commands
The default command completer is symbol_completer, but it makes no
sense for a "show" command to complete on symbols, or anything else,
really.
I wonder whether we should instead make the default be no completer.
That seems like a much larger/complicated audit/change, so I'd like to
move forward with this version, as it'll be covered by tests. I
noticed this because a following patch will add a new
gdb.base/settings.exp testcase that exercises all sorts of details of
settings commands, including completing the show commands, using new
representative "maint test-settings <type or settings command>"
commands.
Also remove the completer for var_string and var_string_noescape
commands. No point in completing symbols when GDB is expecting a
string.

Fix TID parser bug
I noticed this inconsistency in the error messages below:
(gdb) print --1
Left operand of assignment is not an lvalue.
(gdb) thread apply 1 print --1
Thread 1 (Thread 0x7ffff7fb6740 (LWP 17805)):
inverted range
The "inverted range" error happens because get_number_trailer returns
0 to indicate error, but number_or_range_parser::get_number is not
checking for that. I tried detected the error there, but that doesn't
work because number_of_range_parser is used in places that _do_ want
to legitimately handle 0. IMO we should fix get_number_trailer's
interface or use something else when we want to parse 0 too.
I've decided to fix it in a different way, similarly to how
number_or_range_parser::finished was changed in commit 529c08b25ec7

Seems like a good change, even if we tweaked
number_or_range_parser::get_number, as it simplifies
thread_apply_command and makes them consistent with
number_or_range_parser::finished().
We now get the same error message in both cases:

Fix latent bug with custom word point completers
Completion routines that use a custom word point, and that then
recurse into complete_line (e.g., if we make "thread apply" a custom
word point completer, and complete on the command passed as argument),
we stumble on this latent bug:
(gdb) thread apply all pri[TAB]
(gdb) thread apply all priprint
The problem is that there's a spot in complete_line_internal_1 that
rewinds the completion word but does not reflect that change in the
custom word point in the tracker. This patch fixes it.

Fix latent bug in custom word point completion handling
Without this fix, if we switch the "print" completer to custom word
point handling, we regress gdb.base/completion.exp like this:
(gdb) p "break1.c FAIL: gdb.base/completion.exp: complete 'p "break1' (timeout)
The problem is that completing an expression that starts with double
quotes, and resolves to a filename, like this:
(gdb) p "break1[TAB]
would change from this, with current master:
(gdb) p "break1.c"|
^^^^^^^^^^|
\- cursor here
to this:
(gdb) p "break1.c |
^^^^^^^^^^|
\- quote replaced by space
The issue is that completer.c:advance_to_completion_word misses
telling the completion tracker to emulate readline's handling of
completing a string when rl_find_completion_word returns a delimiter.
This commit fixes the latent bug.

cpu/or1k: Add support for orfp64a32 spec
This patch adds support for OpenRISC 64-bit FPU operations on 32-bit cores by
using register pairs. The functionality has been added to OpenRISC architecture
specification version 1.3 as per architecture proposal 14[0].
For supporting assembly of both 64-bit and 32-bit precision instructions we have
defined CGEN_VALIDATE_INSN_SUPPORTED. This allows cgen to use 64-bit bit
architecture assembly parsing on 64-bit toolchains and 32-bit architecture
assembly parsing on 32-bit toolchains. Without this the assembler has issues
parsing register pairs.
This patch also contains a few fixes to the symantics for existing OpenRISC
single and double precision FPU operations.

Dwarf: Don't add nameless modules to partial symbol table
A name for BLOCK DATA in Fortran is optional. If no name has been
assigned, GDB crashes during read-in of DWARF when BLOCK DATA is
represented via DW_TAG_module. BLOCK DATA is used for one-time
initialization of non-pointer variables in named common blocks.
As of now there is no issue when gfortran is used as DW_TAG_module is
not emitted. However, with Intel ifort the nameless DW_TAG_module is
present and has the following form:
...
<1><dd>: Abbrev Number: 7 (DW_TAG_module)
<de> DW_AT_decl_line : 46
<df> DW_AT_decl_file : 1
<e0> DW_AT_description : (indirect string, offset: 0x110): block
data
<e4> DW_AT_high_pc : 0x402bb7
<ec> DW_AT_low_pc : 0x402bb7
...
The missing name leads to a crash in add_partial_symbol, during length
calculation.

Move gdb's xmalloc and friends to new file
When "common" becomes a library, linking will cause a symbol clash,
because "xmalloc" and some related symbols are defined in that

a new file, which is then compiled separately for both gdb and
gdbserver.

When running gdb.dwarf2/nonvar-access.exp with board readnow, we have:
...
FAIL: gdb.dwarf2/nonvar-access.exp: print/x def_implicit_s
...
and 12 more similar failures.
I've tracked this down to the range of main being hardcoded to
[_main, _main+0x10000) in the dwarf assembly:
...
DW_TAG_subprogram {
{name main}
{DW_AT_external 1 flag}
{low_pc [gdb_target_symbol main] DW_FORM_addr}
{high_pc [gdb_target_symbol main]+0x10000 DW_FORM_addr}
} {
...
which overlaps with the .debug_info for the elf-init.c CU (containing
__libc_csu_init and __libc_csu_fini).
Fix this by using function_range to find the actual range of main.

gdb: Check for not allocated/associated values during array slicing
When extracting an array slice we should give up if the array is
not-allocated or not-associated. For Fortran, at least in gfortran
compiled code, the upper and lower bounds are undefined if the array
is not allocated or not associated, in which case performing checks
against these bounds will result in undefined behaviour.
Better then to throw an error if we try to slice such an array. This
changes the error message that the user will receive in these
cases (if they got an error message before). Previously they may have
gotten "slice out of range" now they'll get "array not allocated" or
"array not associated".

The problem happens as follows.
The executable amd64-init-x87-values gets an index (due to target board
cc-with-gdb-index), which looks as follows:
...

The structure of this index is:
...
header : [0x0, 0x18) : size 0x18
culist : [0x18 ,0x28) : size 0x10
typesculist : [0x28, 0x28) : size 0x0
adress area : [0x28, 0x3c) : size 0x14
symbol table : [0x3c, 0x203c) : size 0x2000
constant pool: [0x203c, 0x203c): size 0x0
EOF : 0x203c
...
Note that the symbol table consists entirely of empty slots (where an empty
slot is a pair of 32-bit zeroes), and that the constant pool is empty.
The problem happens here in mapped_index_base::build_name_components:
...
auto count = this->symbol_name_count ();
for (offset_type idx = 0; idx < count; idx++)
{
if (this->symbol_name_slot_invalid (idx))
continue;
const char *name = this->symbol_name_at (idx);
...
when accessing the slot at idx == 0 in the symbol table,
symbol_name_slot_invalid returns false so we calculate name, which is
calculated using 'constant_pool + symbol_table[idx].name', which means we get
name == constant_pool. And given that the constant pool is empty, name now
points past the memory allocated for the index, and when we access name[0] for
the first time in cp_find_first_component_aux, we run into the
heap-buffer-overflow.
Fix this by fixing the definition of symbol_name_slot_invalid:
...
- return bucket.name == 0 && bucket.vec;
+ return bucket.name == 0 && bucket.vec == 0;
...
Tested on x86_64-linux.

[gdb/symtab] Fix symbol loading performance regression
The commit "[gdb/symtab] Fix language of duplicate static minimal symbol"
introduces a performance regression, when loading a cc1 executable build with
-O0 -g and gcc 7.4.0. The performance regression, measured in 'real' time is
about 175%.
The slower execution comes from the fact that the fix in symbol_set_names
makes the call to symbol_find_demangled_name unconditional.
Fix this by reverting the commit, and redoing the fix as follows.
Recapturing the original problem, the first time symbol_set_names is called
with gsymbol.language == lang_auto and linkage_name == "_ZL3foov", the name is
not present in the per_bfd->demangled_names_hash hash table, so
symbol_find_demangled_name is called to demangle the name, after which the
mangled/demangled pair is added to the hashtable. The call to
symbol_find_demangled_name also sets gsymbol.language to lang_cplus.
The second time symbol_set_names is called with gsymbol.language == lang_auto
and linkage_name == "_ZL3foov", the name is present in the hash table, so the
demangled name from the hash table is used. However, the language of the
symbol remains lang_auto.
Fix this by adding a field language in struct demangled_name_entry, and using
the field in symbol_set_names to set the language of gsymbol, if necessary.
Tested on x86_64-linux.

Remove newlines from warnings
ARI pointed out that a recent patch introduced a call to "warning"
with a string that ended in a newline:
https://sourceware.org/ml/gdb-patches/2019-06/msg00000.html
This is generally forbidden, I believe, because warning adds its own
newline.
This patch removes all of the trailing newlines I was able to find. I
searched for 'warning (.*\\n"' and then fixed the ones where the
newline appeared at the end of the string (some had internal
newlines).

Use gdbpy_enter in py-breakpoint.c
A few spots in py-breakpoint.c acquire the GIL manually. However,
because these spots generate events, and because events are expected
to be arbitrary gdb-flavored Python code, it's important to use
gdbpy_enter instead, in order to ensure that the other gdb-related
Python globals are set correctly.
This patch makes this change. Tested on x86-64 Fedora 29.

LD/doc: Clarify `-rpath' option's semantics WRT link-time dependencies
Mention in the description of the `-rpath' LD option the restrictions
the option has with respect to searching link-time dependencies of
shared objects referred in the link. Previously these restrictions were
only documented along with the `-rpath-link' option, which may not be
the place one would consider when looking for the semantics of `-rpath'.
Copy the relevant part of the `-rpath-link' option description then,
splitting the now overlong paragraph into three, for legibility.

(The include of libiberty.h happens in an unusual place due to the

Apply substitute-path to relative filenames as well
When source file path is relative to the build directory (which
is considered a good practice and is enforced in certain buildsystems,
such as meson), gdb only applies substitute-path to the build directory
path. Then gdb appends the source file path to the rewritten build
directory path, and tries to access that.
This fails if either two of the following conditions are true:
a) The user didn't specify substitute-path for the build directory.
This is highly likely, since path substitution for build directories
is not documented anywhere, and since gdb does not tell[0] the user
the path to the build directory, just the source file path.
b) The source file path changed.
This can also easily happen, since a source path that is relative
to the build directory can include any number of directory names
that are not part of the program source tree (starting with the
name of the root directory of the source tree). Gdb will not apply
substitute-path to that relative path, thus there is no way for
the user to tell gdb about these changes.
This commit changes the code to apply substitute-path to all filenames,
both relative and absolute. This way it is possible to do things like:
set substitute-path ../foobar-1.0 /src/my/foobar-1.0
which is completely in line with the user expectations.
This might break unusual cases where build directory path is also
relative (is that even possible?) and happens to match the path
to the source directory (i.e. happens to match a substitution rule).
[0]: There's a "maintenance info symtabs" command that does show the names
of the build directories, but normal users are not required to
know or use that.

Add timestamps to "maint time" output
Currently "maint time" will print the amount of time a command took.
Sometimes, though, it's useful to have a timestamp as well -- for
example if one is correlating a gdb log with some other log.
This patch adds a timestamp to the start and end of each command when
this setting is in effect.
This also removes a "//" comment and changes scoped_command_stats to
use DISABLE_COPY_AND_ASSIGN; two minor things I noticed while working
on the patch.

gdb/riscv: Don't error when decoding a 6 or 8 byte instruction
If the RISC-V prologue scanner finds a 6 or 8 byte instruction we
currently throw an internal error, which is not great for the user.
A mechanism already exists in the prologue scanner to leave
instructions marked as unknown so that we can stop the prologue scan
without raising an error, this is used for all 2 and 4 byte
instructions that are not part of the small set the prologue scanner

Introduce and use make_unique_xstrdup
Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

Use CHAR_BIT instead of NBBY in libctf
On x86-64 Fedora 29, I tried to build a mingw-hosted gdb that targets
ppc-linux. You can do this with:
../binutils-gdb/configure --host=i686-w64-mingw32 --target=ppc-linux \
--disable-{binutils,gas,gold,gprof,ld}
The build failed with these errors in libctf:

libctf: look for BSD versus GNU qsort_r signatures
We cannot just look for any declaration of qsort_r, because some
operating systems have a qsort_r that has a different prototype
but which still has a pair of pointers in the right places (the last two
args are interchanged): so use AC_LINK_IFELSE to check for both
known variants of qsort_r(), and swap their args into a consistent order
in a suitable inline function. (The code for this is taken almost
unchanged from gnulib.)
(Now we are not using AC_LIBOBJ any more, we can use a better name for
the qsort_r replacement as well.)

* ctf-qsort_r.c: ... this.

Improve usability and/or readibility of help and apropos output.
The "help" command can output long list of command names or classes.
Use the title style to style the command names or classes to make
the output more readable.
Similarly, change "apropos" command to also style the command names.
It is sometimes unclear why "apropos REGEXP" lists some commands,
and then the user has to manually do 'help command' for all commands
listed by "apropos" to see more details about the matching commands.
=> Add an optional flag -v so that "apropos -v REGEXP":
* outputs the full documentation of matching commands.
* highlights the documentation parts matching REGEXP.

Have 'show style' and its subcommands using a style to style its output.
This allows the GDB user or developer to use 'show style' to visually see
with one command how all the current styles look like.
Add 2 new styles highlight style, title style and fputs_highlighted function.
Highlight style is used by fputs_highlighted to highlight the parts of
its char *STR argument that match a HIGHLIGHT regexp.
This (and the title style) will be used in a following patch.

Implement | (pipe) command.
The pipe command allows to run a GDB command, and pipe its output
to a shell command:
(gdb) help pipe
Send the output of a gdb command to a shell command.
Usage: | [COMMAND] | SHELL_COMMAND
Usage: | -d DELIM COMMAND DELIM SHELL_COMMAND
Usage: pipe [COMMAND] | SHELL_COMMAND
Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND
Executes COMMAND and sends its output to SHELL_COMMAND.
The -d option indicates to use the string DELIM to separate COMMAND
from SHELL_COMMAND, in alternative to |. This is useful in
case COMMAND contains a | character.
With no COMMAND, repeat the last executed command
and send its output to SHELL_COMMAND.
(gdb)
For example:
(gdb) pipe print some_data_structure | grep -B3 -A3 something
The pipe character is defined as an alias for pipe command, so that
the above can be typed as:
(gdb) | print some_data_structure | grep -B3 -A3 something
If no GDB COMMAND is given, then the previous command is relaunched,
and its output is sent to the given SHELL_COMMAND.
This also defines convenience vars $_shell_exitcode and $_shell_exitsignal
to record the exit code and exit signal of the last shell command
launched by GDB e.g. by "shell", "pipe", ...

Add previous_saved_command_line to allow a command to repeat a previous command.
Currently, a previous command can be repeated when the user types an
empty line. This is implemented in handle_line_of_input by
returning saved_command_line in case an empty line has been input.
If we want a command to repeat the previous command, we need to save
the previous saved_command_line, as when a command runs, the saved_command_line
already contains the current command line of the command being executed.
As suggested by Tom, the previous_saved_command_line is made static.
At the same time, saved_command_line is also made static.
The support functions/variables for the repeat command logic are now all
located inside top.c.

libctf: fix a number of build problems found on Solaris and NetBSD
- Use of nonportable <endian.h>
- Use of qsort_r
- Use of zlib without appropriate magic to pull in the binutils zlib
- Use of off64_t without checking (fixed by dropping the unused fields
that need off64_t entirely)
- signedness problems due to long being too short a type on 32-bit
platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be
used only for functions that return ctf_id_t
- One lingering use of bzero() and of <sys/errno.h>
All fixed, using code from gnulib where possible.
Relatedly, set cts_size in a couple of places it was missed
(string table and symbol table loading upon ctf_bfdopen()).

Don't crash is dwarf_decode_macro_bytes's 'body' is NULL, even when '!is_define'
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1715008
On commit 7bede82892a06e6c26989803e70f53697392dcf9 ("Don't crash if
dwarf_decode_macro_bytes's 'body' is NULL"), I was too strict when
checking if 'body' is NULL: the check only comprised the case when
'is_define' is true. However, the corruption of .debug_macro by
rpmbuild's "debugedit" also affects the case when 'is_define' is
false, i.e., when the macro is being undefined.
This commit improves the check and covers both cases now. This has
been tested on Fedora 30 with a problematic debuginfo, and I don't see
a segfault anymore.
OK to push?

Fix crash in cp_print_value_fields
PR c++/20020 concerns a crash in cp_print_value_fields. The immediate
cause is that cp_print_value_fields does not handle the case where
value_static_field fails. This is fixed in this patch by calling
cp_print_static_field from the "try" block.
Digging a bit deeper, the error occurs because GCC does not emit a
DW_AT_const_value for a static constexpr member appearing in a
template class. I've filed a GCC bug for this.

Add "set print finish"
A user wanted to be able to disable the display of the value when
using "finish" -- but still have the value entered into the value
history in case it was useful later on. Part of the rationale here is
that sometimes the value might be quite large, or expensive to display
(in their case this was compounded by a rogue pretty-printer).
This patch implements this idea.

Remove find_old_style_renaming_symbol
We found a case where a "bt" was very slow with Ada code. Profiling
with callgrind showed this to be primarily due to calls to
find_old_style_renaming_symbol. Because new-style renaming symbols
were implemented in 2007, it seems safe enough to remove this old
code.
A "-batch -ex bt" test on a large Ada program improves from:
13.23user 0.57system 0:13.82elapsed 99%CPU (0avgtext+0avgdata 571408maxresident)k
to
4.25user 0.48system 0:04.74elapsed 99%CPU (0avgtext+0avgdata 559844maxresident)k
with this patch.
Tested on x86-64 Fedora 29. Joel reviewed this internally; and as it
is Ada-specific, I am checking it in.

binutils: CTF support for objdump and readelf
This introduces CTF support for objdump and readelf. objdump has the
following new arguments:
--ctf=SECTION: display CTF in the given SECTION
--ctf-parent=SECTION: name of CTF section that is the parent of this section
readelf has the above, and these two as well:
--ctf-symbols=SECTION: name of symbol table section (optional)
--ctf-strings=SECTION: name of string table section (optional)
(objdump can always use BFD machinery to determine the applicable string
and symbol tables automatically, so these arguments are unnecessary.)
Nearly all the work is done by the ctf_dump machinery in libctf: most of
the remaining work is option-processing and section-reading, and thus is
different for objdump and readelf: the minimal amount of similar code
remaining is, in my view, too small to share, particularly given that
objdump uses ctf_bfdopen() and readelf uses ctf_simple_open() since it
doesn't have a bfd.
I am not particularly satisfied with the way resources are freed in
either of these (I was forced to do it at the top level, for lack of
anywhere else to free resources allocated during option processing), but
I can't see any better way to do it without introducing new
infrastructure for no other purpose.
There are essentially arbitrary ordering changes to the Makefile.in's
order of libtool-related stuff that I can't get rid of, but they have no
semantic effect. (It is possible that some hunks of these changes could
be dropped, but that seems a bit risky to me.)

This facility allows you to associate regions of type IDs with *labels*,
a labelled tiling of the type ID space. You can use these to define
CTF containers with distinct parents for distinct ranges of the ID
space, or to assist with parallelization of CTF processing, or for any
other purpose you can think of.
Notably absent from here (though declared in the API header) is any way
to define new labels: this will probably be introduced soon, as part of
the linker deduplication work. (One existed in the past, but was deeply
tied to the Solaris CTF file generator and had to be torn out.)

another writable one, by copying the necessary types.

libctf: lookups by name and symbol
These functions allow you to look up types given a name in a simple
subset of C declarator syntax (no function pointers), to look up the
types of variables given a name, and to look up the types of data
objects and the type signatures of functions given symbol table offsets.
(Despite its name, one function in this commit, ctf_lookup_symbol_name(),
is for the internal use of libctf only, and does not appear in any
public header files.)

libctf: core type lookup
Finally we get to the functions used to actually look up and enumerate
properties of types in a container (names, sizes, members, what type a
pointer or cv-qual references, determination of whether two types are
assignment-compatible, etc).
With a very few exceptions these do not work for types newly added via
ctf_add_*(): they only work on types in read-only containers, or types
added before the most recent call to ctf_update().
This also adds support for lookup of "variables" (string -> type ID
mappings) and for generation of C type names corresponding to a type ID.

libctf: ELF file opening via BFD
These functions let you open an ELF file with a customarily-named CTF
section in it, automatically opening the CTF file or archive and
associating the symbol and string tables in the ELF file with the CTF
container, so that you can look up the types of symbols in the ELF file
via ctf_lookup_by_symbol(), and so that strings can be shared between
the ELF file and CTF container, to save space.
It uses BFD machinery to do so. This has now been lightly tested and
seems to work. In particular, if you already have a bfd you can pass
it in to ctf_bfdopen(), and if you want a bfd made for you you can
call ctf_open() or ctf_fdopen(), optionally specifying a target (or
try once without a target and then again with one if you get
ECTF_BFD_AMBIGUOUS back).
We use a forward declaration for the struct bfd in ctf-api.h, so that
ctf-api.h users are not required to pull in <bfd.h>. (This is mostly
for the sake of readelf.)

libctf: mmappable archives
If you need to store a large number of CTF containers somewhere, this
provides a dedicated facility for doing so: an mmappable archive format
like a very simple tar or ar without all the system-dependent format
horrors or need for heavy file copying, with built-in compression of
files above a particular size threshold.
libctf automatically mmap()s uncompressed elements of these archives, or
uncompresses them, as needed. (If the platform does not support mmap(),
copying into dynamically-allocated buffers is used.)
Archive iteration operations are partitioned into raw and non-raw
forms. Raw operations pass thhe raw archive contents to the callback:
non-raw forms open each member with ctf_bufopen() and pass the resulting
ctf_file_t to the iterator instead. This lets you manipulate the raw
data in the archive, or the contents interpreted as a CTF file, as
needed.
It is not yet known whether we will store CTF archives in a linked ELF
object in one of these (akin to debugdata) or whether they'll get one
section per TU plus one parent container for types shared between them.
(In the case of ELF objects with very large numbers of TUs, an archive
of all of them would seem preferable, so we might just use an archive,
and add lzma support so you can assume that .gnu_debugdata and .ctf are
compressed using the same algorithm if both are present.)
To make usage easier, the ctf_archive_t is not the on-disk
representation but an abstraction over both ctf_file_t's and archives of
many ctf_file_t's: users see both CTF archives and raw CTF files as
ctf_archive_t's upon opening, the only difference being that a raw CTF
file has only a single "archive member", named ".ctf" (the default if a
null pointer is passed in as the name). The next commit will make use
of this facility, in addition to providing the public interface to
actually open archives. (In the future, it should be possible to have
all CTF sections in an ELF file appear as an "archive" in the same
fashion.)
This machinery is also used to allow library-internal creators of
ctf_archive_t's (such as the next commit) to stash away an ELF string
and symbol table, so that all opens of members in a given archive will
use them. This lets CTF archives exploit the ELF string and symbol
table just like raw CTF files can.
(All this leads to somewhat confusing type naming. The ctf_archive_t is
a typedef for the opaque internal type, struct ctf_archive_internal: the
non-internal "struct ctf_archive" is the on-disk structure meant for
other libraries manipulating CTF files. It is probably clearest to use
the struct name for struct ctf_archive_internal inside the program, and
the typedef names outside.)

libctf: opening
This fills in the other half of the opening/creation puzzle: opening of
already-existing CTF files. Such files are always read-only: if you
want to add to a CTF file opened with one of the opening functions in
this file, use ctf_add_type(), in a later commit, to copy appropriate
types into a newly ctf_create()d, writable container.
The lowest-level opening functions are in here: ctf_bufopen(), which
takes ctf_sect_t structures akin to ELF section headers, and
ctf_simple_open(), which can be used if you don't have an entire ELF
section header to work from. Both will malloc() new space for the
buffers only if necessary, will mmap() directly from the file if
requested, and will mprotect() it afterwards to prevent accidental
corruption of the types. These functions are also used by ctf_update()
when converting types in a writable container into read-only types that
can be looked up using the lookup functions (in later commits).
The files are always of the native endianness of the system that created
them: at read time, the endianness of the header magic number is used to
determine whether or not the file needs byte-swapping, and the entire
thing is aggressively byte-swapped.
The agggressive nature of this swapping avoids complicating the rest of
the code with endianness conversions, while the native endianness
introduces no byte-swapping overhead in the common case. (The
endianness-independence code is also much newer than everything else in
this file, and deserves closer scrutiny.)
The accessors at the top of the file are there to transparently support
older versions of the CTF file format, allowing translation from older
formats that have different sizes for the structures in ctf.h:
currently, these older formats are intermingled with the newer ones in
ctf.h: they will probably migrate to a compatibility header in time, to
ease readability. The ctf_set_base() function is split out for the same
reason: when conversion code to a newer format is written, it would need
to malloc() new storage for the entire ctf_file_t if a file format
change causes it to grow, and for that we need ctf_set_base() to be a
separate function.
One pair of linked data structures supported by this file has no
creation code in libctf yet: the data and function object sections read
by init_symtab(). These will probably arrive soon, when the linker comes
to need them. (init_symtab() has hardly been changed since 2009, but if
any code in libctf has rotted over time, this will.)
A few simple accessors are also present that can even be called on
read-only containers because they don't actually modify them, since the
relevant things are not stored in the container but merely change its
operation: ctf_setmodel(), which lets you specify whether a container is
LP64 or not (used to statically determine the sizes of a few types),
ctf_import(), which is the only way to associate a parent container with
a child container, and ctf_setspecific(), which lets the caller
associate an arbitrary pointer with the CTF container for any use. If
the user doesn't call these functions correctly, libctf will misbehave:
this is particularly important for ctf_import(), since a container built
against a given parent container will not be able to resolve types that
depend on types in the parent unless it is ctf_import()ed with a parent
container with the same set of types at the same IDs, or a superset.
Possible future extensions (also noted in the ctf-hash.c file) include
storing a count of things so that we don't need to do one pass over the
CTF file counting everything, and computing a perfect hash at CTF
creation time in some compact form, storing it in the CTF file, and
using it to hash things so we don't need to do a second pass over the
entire CTF file to set up the hashes used to go from names to type IDs.
(There are multiple such hashes, one for each C type namespace: types,
enums, structs, and unions.)

libctf: creation functions
The CTF creation process looks roughly like (error handling elided):
int err;
ctf_file_t *foo = ctf_create (&err);
ctf_id_t type = ctf_add_THING (foo, ...);
ctf_update (foo);
ctf_*write (...);
Some ctf_add_THING functions accept other type IDs as arguments,
depending on the type: cv-quals, pointers, and structure and union
members all take other types as arguments. So do 'slices', which
let you take an existing integral type and recast it as a type
with a different bitness or offset within a byte, for bitfields.
One class of THING is not a type: "variables", which are mappings
of names (in the internal string table) to types. These are mostly
useful when encoding variables that do not appear in a symbol table
but which some external user has some other way to figure out the
address of at runtime (dynamic symbol lookup or querying a VM
interpreter or something).
You can snapshot the creation process at any point: rolling back to a
snapshot deletes all types and variables added since that point.
You can make arbitrary type queries on the CTF container during the
creation process, but you must call ctf_update() first, which
translates the growing dynamic container into a static one (this uses
the CTF opening machinery, added in a later commit), which is quite
expensive. This function must also be called after adding types
and before writing the container out.
Because addition of types involves looking up existing types, we add a
little of the type lookup machinery here, as well: only enough to
look up types in dynamic containers under construction.

libctf: implementation definitions related to file creation
We now enter a series of commits that are sufficiently tangled that
avoiding forward definitions is almost impossible: no attempt is made to
make individual commits compilable (which is why the build system does
not reference any of them yet): the only important thing is that they
should form something like conceptual groups.
But first, some definitions, including the core ctf_file_t itself. Uses
of these definitions will be introduced in later commits.

libctf: hashing
libctf maintains two distinct hash ADTs, one (ctf_dynhash) for wrapping
dynamically-generated unknown-sized hashes during CTF file construction,
one (ctf_hash) for wrapping unchanging hashes whose size is known at
creation time for reading CTF files that were previously created.
In the binutils implementation, these are both fairly thin wrappers
around libiberty hashtab.
Unusually, this code is not kept synchronized with libdtrace-ctf,
due to its dependence on libiberty hashtab.

libctf: low-level list manipulation and helper utilities
These utilities are a bit of a ragbag of small things needed by more
than one TU: list manipulation, ELF32->64 translators, routines to look
up strings in string tables, dynamically-allocated string appenders, and
routines to set the specialized errno values previously committed in
<ctf-api.h>.
We do still need to dig around in raw ELF symbol tables in places,
because libctf allows the caller to pass in the contents of string and
symbol sections without telling it where they come from, so we cannot
use BFD to get the symbols (BFD reasonably demands the entire file). So
extract minimal ELF definitions from glibc into a private header named
libctf/elf.h: later, we use those to get symbols. (The start-of-
copyright range on elf.h reflects this glibc heritage.)

libctf: lowest-level memory allocation and debug-dumping wrappers
The memory-allocation wrappers are simple things to allow malloc
interposition: they are only used inconsistently at present, usually
where malloc debugging was required in the past.
These provide a default implementation that is environment-variable
triggered (initialized on the first call to the libctf creation and
file-opening functions, the first functions people will use), and
a ctf_setdebug()/ctf_getdebug() pair that allows the caller to
explicitly turn debugging off and on. If ctf_setdebug() is called,
the automatic setting from an environment variable is skipped.

aarch64: add STO_AARCH64_VARIANT_PCS and DT_AARCH64_VARIANT_PCS
The bottom 2 bits of st_other are used for visibility, the top 6 bits are
de facto reserved for processor specific use. This patch defines a
bits to mark function symbols that follow a variant procedure call standard
with different register usage convention.
A dynamic tag is also defined that marks modules with R_<CLS>_JUMP_SLOT
relocations referencing symbols marked with STO_AARCH64_VARIANT_PCS.
This can be used by dynamic linkers that support lazy binding to decide
what registers need to be preserved during symbol resolution.
binutils/ChangeLog:
* readelf.c (get_aarch64_dynamic_type): Handle DT_AARCH64_VARIANT_PCS.
(get_aarch64_symbol_other): New, handles STO_AARCH64_VARIANT_PCS.
(get_symbol_other): Call get_aarch64_symbol_other.
include/ChangeLog:
* elf/aarch64.h (DT_AARCH64_VARIANT_PCS): Define.
(STO_AARCH64_VARIANT_PCS): Define.

Constify target_ops::follow_exec
I noticed that target_ops::follow_exec took a "char *" parameter,
where "const char *" would be more correct. This patch changes this
(and related functions) to be constified.

gdb/riscv: Improve flen length determination
This solves an assertion failure when a remote provides a target
description which only refers to floating point registers by their
hardware name (e.g. f0), rather than their ABI name (e.g. ft0). GDB
assumed that should the floating point register feature be presented,
it would contain a register called ft0.
The floating point length is now instead determined by searching for
the same register, but looking for any of its aliases.

* riscv-tdep.c (riscv_gdbarch_init): Support determining flen from
target descriptions using exclusively floating point register name
aliases.

gdb/fortran: Handle gdbarch_floatformat_for_type returning nullptr
In this commit:
commit 34d11c682fd96c7dbe3ebd6cd9033e65d51ec7a3
Date: Fri May 3 15:23:55 2019 +0100
gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
GDB was changed such that the Fortran's 16-byte float format was
obtained by calling gdbarch_floatformat_for_type instead of just using
gdbarch_long_double_format as it was before.
The problem with this default_floatformat_for_type can return NULL in
some cases, and the code introduced in 34d11c682f didn't consider
this.
This commit introduces several alternative strategies for finding a
suitable 16-byte floating point type. First GDB calls
gdbarch_floatformat_for_type (this was what 34d11c682f added), if this
returns null GDB will use gdbarch_long_double_format if it is the
correct size (this was the format used before 34d11c682f). Finally,
if neither of the above provides a suitable type then GDB will create
a new dummy type.
This final dummy type is unlikely to provide an correct debug
experience as far as examining the 16-byte floats, but it should
prevent GDB crashing.

[gdb/cli] Fix use of uninitialized variable in complete_command
When building gdb on ubuntu 16.04 with gcc 5.4.0, and running the gdb
testsuite we run into:
...
FAIL: gdb.linespec/explicit.exp: complete after -line: \
cmd complete "b -line argument " (timeout)
...
The failure is reproducible outside the testsuite like this:
...
$ gdb -q build/gdb/testsuite/outputs/gdb.linespec/explicit/explicit \
-ex "complete b -line argument"
Reading symbols from \
build/gdb/testsuite/outputs/gdb.linespec/explicit/explicit...
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_M_create
Aborted (core dumped)
...
The problem is here in complete_command:
...
completion_result result = complete (arg, &word, "e_char);
std::string arg_prefix (arg, word - arg);
if (result.number_matches != 0)
...
The problem is that the word variable is not initialized when
result.number_matches == 0, but the variable is still used in the arg_prefix
initialization.
Fix this by guarding the arg_prefix initialization with the
'result.number_matches != 0' test.

AArch64: Implement choice between Cortex-A53 erratum workarounds. (PR ld/24373)
The Cortex-A53 erratum currently has two ways it can resolve the erratum when
using the flag --fix-cortex-a53-843419:
1) If the address is within the range of an ADR instruction it rewrites the ADRP
into an ADR, and those doesn't need the use of a veneer.
2) If the address is not within range, it adds a branch to a veneer which will
execute the final bit of the erratum workaround and branch back to the call
site.
When we do this we always generate the veneers and we always align the size of
the text section to 4KB. This is because we only know which workaround we can
use after all linking has finished and all addresses are known. This means even
though the veneers are not used, we still generate the section and we still
change the size of the input section.
This is problematic for small memory devices as this would require the user to
take about a ~4KB hit in memory even though it's not even used.
Since there's no real way to restart the linking process from the final write
phase this patch solves the issue by allowing the user more control over which
erratum workaround gets used.
Concretely this changes the option --fix-cortex-a53-843419 to take optional
arguments --fix-cortex-a53-843419[=full|adr|adrp]
- full (default): Use both ADRP and ADR workaround. This is equivalent to not
specifying any options and is the default behavior before this
patch.
- adr: Only use the ADR workaround, this will not cause any increase in binary
size but linking will fail if the referenced address is out of range of
an ADR instruction.
- adrp: Use only the ADRP workaround, this will never rewrite your ADRP.
In the cases where the user knows how big their binaries are the `adr` option
would prevent the unneeded overhead.

Fix PR 24571 - Relaxation does not shorten jmp or call to target at pc-relative range boundary
The range check done to transform an absolute call/jump to a pc-relative one is
off-by-one, and that causes this shortening optimization to be missed if the
branch target is right at the range boundary.
In the non-shrinkable case, the range is what is mentioned in the ISA - -4094
bytes in the backward direction, and 4096 bytes in the positive direction.
In the shrinkable case, the forward jump range increases by two bytes (deleted
because of the shortening from call/jmp to rcall/rjmp), and therefore, the
range is -4094 in the reverse, and 4098 in the positive direction.
Fix the ranges for !shrinkable and shrinkable cases, and add a test caes to
ensure jumps to max forward and backward ranges get relaxed to rjmp.

Fix PR 24564 - link fails for some rcalls/rjmps with wraparound
The current code to compute relative distance in the wrap around case does not
handle the edge case of the target (after adjusting for implicit PC increment)
being exactly half of the wrap around distance. This patch fixes that and adds a
testcase.
The range for a forward relative jump call is 4096 bytes ((2 * 2047) + (2 bytes
for the implicit PC increment)). If the target of the jump is at a distance of
4098 bytes, it is out of range for a forward jump - however, a backward jump can
still reach that address if pmem-wrap-around is 8192.
Assume address 0 has rjmp to address 4098. With a wrap around of 8192 and
*without* adjusting for the implicit PC increment of 2 bytes, rjmp .-4096 will
jump to address 4096 (wrap around at 8192 and decreasing addresses from then
on). Adjusting 2 bytes for the implicit PC increment, the actual target is 4098.
avr_relative_distance_considering_wrap_around though, does the wrap around only
if the passed in distance is less than half of the wrap around distance. In this
case, it is exactly equal to half (original distance 4098, adjusted distance of
4096 and wraparound of 8192), and the bypassed wrap around causes the reloc
overflow error.
Fix by wrapping around even if adjusted distance is equal to half of wrap around
distance.

gdb/fortran: Use floatformats_ia64_quad for fortran 16-byte floats
PR gdb/18644 is caused by GDB using the wrong floating point format
for gfortran's 16-byte floating point type, including when the 16-byte
float is used as the component of a 32-byte complex type.
This commit addresses the issue in two places, first in i386-tdep.c,
there is already some code to force the use of floatformats_ia64_quad
for specific named types, this is extended to include the type names
that gfortran uses for its 16-byte floats.
Second, the builtin 16-byte float type (in f-lang.c) is changed so it
no longer uses gdbarch_long_double_format. On i386 this type is not
16-bytes, but is smaller, this is not what gfortran is expecting.
Instead we now use gdbarch_floatformat_for_type and ask for a
16-byte (128 bit) type using the common gfortran type name. This is
then spotted in i386-tdep.c (thanks to the first change above) and we
again get floatformats_ia64_quad returned.
This patch was tested on X86-64/GNU-Linux using '--target_board=unix'
and '--target_board=unix/-m32', and resolves all of the known failures
associated with PR gdb/18644. I've also added the test case from the
original bug report.

testsuite: Record all gdb input to gdb.in
When debugging testsuite failures, it can be awkward parsing gdb.log to
obtain all the commands run in order to manually re-run the test.
This patch adds the functionality to save all gdb commands to the file gdb.in
when the testsuite is run. The file is saved in the directory for the test and
if gdb is restarted then .1, .2, .3 etc is added to the filename.
Once a test has been run, the .in file can be used to re-run the test in the
following way:
gdb -x outputs/gdb.store/gdb.in outputs/gdb.store/store
The code works by intercepting send_gdb. I've added a TYPE to ensure that any
commands that would destroy the playback are kept from the log (for example the
Y from an answer to a y/n question).
Adds library function standard_output_file_with_gdb_instance to open a file
postfixed with count of the gdb instance. Ensure this count is reset when a new
.exp script is run.
I've re-run a random selection of .in files to check they do not error. Logs with
commands such as "attach <pid>" will not directly work when re-run.

testsuite: Disable some tests when logging
Fix up all failures encountered when running the testsuite with
GDB_DEBUG="infrun".
Some tests rely on enabling debugging for various components. With
debugging on, this will be lost to the debug file.
Disable separate tty for mi tests when debugging. This currently
does not work.
disasm.c should send errors to the stderr instead of the logfile.
Note that enabling debug for other components might still cause
additional errors above what has been fixed here.

testsuite: Add option to capture GDB debug
Add both board option and environment variable which enables gdb
debug via a comma separated list and sends it to the file gdb.debug,
located in the output directory for the current test. Document this.
Add support for the environment variable in the Makefile.
The testsuite can be run with gdb debug enabled in the following way:
make check GDB_DEBUG="infrun,target,remote"
A Test with multiple invocations of GDB will all append debug to the
same log file.
gdb/testsuite/ChangeLog:
* Makefile.in: Pass through GDB_DEBUG.

(gdb,debug): Add board setting.
* lib/gdb.exp (default_gdb_start): Start debugging.

Add debug redirect option
Currently, when logging is enabled, output will be sent to both a
logfile and standard terminal output. The redirect option sends output
only to the logfile. This includes all debug output.
Add the option to redirect debug output seperately to normal
output, using the cli command:
set logging debugredirect on
By setting this and enabling logging, all output and debug will
be sent to the logfile. The user will still see all output but
no debug output.
This causes a change in behaviour for anyone currently using
logging redirect, as now only output will be redirected. Users
will have to issue the additional command above to also redirect
debug.
Expand ui-redirect.exp cover the changes.
gdb/ChangeLog:
* cli/cli-interp.c (struct saved_output_files): Add saved entry.

Change file close behavior for tee_file
Instead of using two bools to decide if the files should close when tee_file
is closed, make file one stay open and file two close. This simplifies the
use cases for it.
Inline the make_logging_output into the calling functions (the logic here
looks ugly in order to simplify a later change).

MI: Add new command -complete
There is a CLI command 'complete' intended to use with emacs. Such a command
would also be useful for MI frontends, when separate CLI and MI channels cannot

This error happens as follows.
The function find_partial_die has a cu argument, but returns a pdi which may
or may not be from that cu:
...
/* Find a partial DIE at OFFSET, which may or may not be in CU,
except in the case of .debug_types DIEs which do not reference
outside their CU (they do however referencing other types via
DW_FORM_ref_sig8). */
static struct partial_die_info *
find_partial_die (sect_offset sect_off, int offset_in_dwz, struct dwarf2_cu *cu)
...
So the pdi returned by find_partial_die here in partial_die_parent_scope may
be from another cu:
...
partial_die_parent_scope (struct partial_die_info *pdi,
struct dwarf2_cu *cu)
{
const char *grandparent_scope;
struct partial_die_info *parent, *real_pdi;
/* We need to look at our parent DIE; if we have a DW_AT_specification,
then this means the parent of the specification DIE. */
real_pdi = pdi;
while (real_pdi->has_specification)
real_pdi = find_partial_die (real_pdi->spec_offset,
real_pdi->spec_is_dwz, cu);
parent = real_pdi->die_parent;
...
in which case both real_pdi and parent will be not from cu, but from another
one, say cu2.
Subsequently, cu's comp_unit_obstack is used to set parent->scope:
...
parent->scope = typename_concat (&cu->comp_unit_obstack,
grandparent_scope,
parent->name, 0, cu);
...
So, we use cu->comp_unit_obstack to assign a value to the scope field of
a pdi belonging to cu2, and when cu is deleted, the scope field points to a
freed value.
Fix this by making find_partial_die return the cu corresponding to the
returned pdi, and handling this at the call sites.
Tested on x86_64-linux.

Make stap-probe.c:stap_parse_register_operand's "regname" an std::string
This patch simplifies the code of
stap-probe.c:stap_parse_register_operand by making "regname" an
std::string. No functionality change.
I'm this code's maintainer, so I'm pushing this as it's a fairly
trivial patch.
gdb/ChangeLog:
2019-05-16 Sergio Durigan Junior <sergiodj@redhat.com>
* stap-probe.c (stap_parse_register_operand): Make "regname" an
"std::string", simplifying the algorithm.

Fix complaint string formatting on stap-probe.c
I think the string formatting for complaints was messed up by Tom's
patch to simplify the complaint mechanism. This small and trivial
patch fixes them.
Pushed as obvious.
gdb/ChangeLog:
2019-05-16 Sergio Durigan Junior <sergiodj@redhat.com>
* stap-probe.c (handle_stap_probe): Fix complaint formatting.

Slightly improve logic of some operations on stap-probe.c
This patch contains three very small improvement on the logic of some
operations we do on stap-probe.c. They don't change what the code
does.
Pushed as obvious.
gdb/ChangeLog:
2019-05-16 Sergio Durigan Junior <sergiodj@redhat.com>
* stap-probe.c (stap_parse_register_operand): Make "if (*p->arg ==
'-')" and "else if".
(stap_parse_single_operand): Join checks for
"gdbarch_stap_parse_special_token_p" and
"gdbarch_stap_parse_special_token" in the same "if" statement.
Invert check when verifying for operation on register
displacement.

Update some comments on stap-probe.c
Some functions's comments were not entirely correct on stap-probe.c,
so this patch updates them.
Pushed as obvious.

Bool-ify stap-probe.c and stap-related code on i386-tdep.c
This simple patch converts a bunch of "int"s to "bool" on stap-probe.c
and on the stap-related code present on i386-tdep.c.
Pushed as obvious (+ I'm the maintainer of this code).
gdb/ChangeLog:
2019-05-16 Sergio Durigan Junior <sergiodj@redhat.com>
* i386-tdep.c (i386_stap_parse_special_token_triplet): Change

Fix darwin-nat.c build
John Marshall pointed out that darwin-nat.c fails to build:
CXX darwin-nat.o
../../../binutils-gdb/gdb/darwin-nat.c:1709:8: error: must use 'class' tag to refer to type 'thread_info' in this scope
for (thread_info *it : all_threads ())
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/mach/thread_act.h:240:15: note:
class 'thread_info' is hidden by a non-type declaration of 'thread_info' here
kern_return_t thread_info
Mach has a thread_info() function declared in that header, which darwin-nat.c #includes.
This patch fixes the problem by reintroducing the struct keyword.
gdb/ChangeLog
2019-05-16 Tom Tromey <tromey@adacore.com>
* darwin-nat.c (thread_info_from_private_thread_info): Add struct

Don't crash if dwarf_decode_macro_bytes's 'body' is NULL
Hi,
Ref.: https://bugzilla.redhat.com/show_bug.cgi?id=1708192
https://bugzilla.redhat.com/show_bug.cgi?id=1708786
During the Fedora RPM build process, gdb-add-index is invoked to
extract the DWARF index from the binary, and GDB will segfault because
dwarf2read.c:parse_definition_macro's 'body' variable is NULL.
The underlying problem is that Fedora's rpm-build's "debugedit"
program will silently corrupt .debug_macro strings when a binary is
compiled with -g3. This is being taken care of by Mark Wielaard,
here:
https://bugzilla.redhat.com/show_bug.cgi?id=1708786
However, I still feel it's important to make GDB more resilient
against invalid DWARF input, so I'm proposing this rather simple patch
to catch the situation when "body == NULL" (i.e., it's probably been
corrupted) and issue a complaint. This is not a real fix to the
problem, of course, but at least GDB is able to finish without
segfaulting.
OK for master?

.file file number checking
This adds another test for file numbers given in .file directives,
checking that the value can be represented as an unsigned int and that
a memory allocation expression doesn't overflow. I removed a test
added recently since an earlier test (num < 1) already covers the
(num < 0) case.

GDB (s12z): Improve reliability of the stack unwinder.
Previously, the stack unwinder searched through consecutive bytes for values
which it thought might be the start of a stack mutating operation.
This was error prone, because such bytes could also be the operands of other
instructions. This change uses the opcodes api to interpret the code in each
frame.

Fix assertion failure in coerce_unspec_val_to_type
coerce_unspec_val_to_type does:
set_value_address (result, value_address (val));
However, this is only valid for lval_memory. This patch changes this
code to only set the address for lval_memory values.
This seems like an ordinary oversight in coerce_unspec_val_to_type,
and a test case would be difficult to write, so I'm submitting it
without a test case.
Tested on x86-64 Fedora 29; plus using an Ada program that exhibits
the bug (but which cannot be shared).

[gdb/testsuite] Fix base address selection entry encoding in dw2-skip-prologue.S
A base address selection entry in a location list consist of two (constant or
relocated) address offsets. The two offsets are the same size as an address
on the target machine.
The test-case gdb.dwarf2/dw2-skip-prologue.S encodes a base address selection
entry using .4byte, which is incorrect for 8-byte pointer size. [ Which
triggers an assert in dwz, see PR dwz/24172. ]

Fix GDB build when using --disable-gdbmi
Since commit
b4be1b064860 ("Fix MI output for multi-location breakpoints")
we get this error when building with --disable-gdbmi:
CXXLD gdb
/home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)'
This is due to breakpoint.c using a function defined in mi/mi-main.c, even
though mi/mi-main.c isn't included in the build.
To fix it, use the flags feature of ui_out. mi_ui_out has the new
fix_multi_location_breakpoint_output flag set for versions >= 3. Also,
move the global variable fix_multi_location_breakpoint_output to
breakpoint.c, so it can be read there even when we build without MI. I
renamed it to fix_multi_location_breakpoint_output_globally so it
doesn't clash with the new enumerator.

cc-with-tweaks: show dwz stderr and verify result
When running the gdb.base/index-cache.exp test case with the
cc-with-dwz-m board, I noticed that the final executable didn't actually
contain a .gnu_debugaltlink section with the name of the external dwz
file:
$ readelf --debug-dump=links testsuite/outputs/gdb.base/index-cache/index-cache
* empty *
Running dwz by hand, I realized it's because dwz complains that the
output .debug_info section is empty and fails:
$ gcc ~/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.c -g3 -O0 -o a && cp a b
$ dwz -m foo a b
dwz: foo: .debug_info section not present
$ echo $?
1
This is because index-cache.c is trivial (just an empty main) and dwz
doesn't find anything to factor out to the dwz file. [1]
I think that cc-with-tweaks should fail in this scenario: if the user
asks for an external dwz file to be generated (the -m flag), then it
should be an error if cc-with-tweaks doesn't manage to produce an
executable with the proper link to this external dwz file. Otherwise,
the test runs with a regular non-dwzified executable, which gives a
false sense of security about whether the feature under test works with
dwzified executables.
So this patch adds checks for that after invoking dwz. It also removes
the 2>&1 to allow the error message to be printed like so:
Running /home/smarchi/src/binutils-gdb/gdb/testsuite/gdb.base/index-cache.exp ...
gdb compile failed, dwz: /home/smarchi/build/binutils-gdb/gdb/testsuite/outputs/gdb.base/index-cache/index-cache.dwz: .debug_info section not present
- In the -m case (multi-file compression), we check if the expected output file
exists.
- In the -z case (single-file compression), we check if the file
contents has changed. This should catch cases where dwz doesn't modify the
file because it's not worth it.
It was chosen not to check for dwz's exit code, as it is not very
reliable up to dwz 0.12.
With this patch, fewer tests will pass than before with the
cc-with-dwz and cc-with-dwz-m boards, but those were false positives
anyway, as the test ran with regular executables.
[1] Note that dwz has been patched by Tom de Vries to work correctly in
this case, so we can use dwz master to run the test:

Two minor constifications
I noticed a couple of spots where a "char *" was used where a
"const char *" made more sense. This patch fixes both of them.
Tested by rebuilding.

[gas][testsuite] Don't specify arch in testsuite output
My testcase matched against a file format of elf64-littleaarch64 in the
objdump output. This was unnecessarily restrictive and causes testcase
failures on aarch64_be.
Here we remove that restriction.
Committed as obvious.
Testing done on aarch64_be-none-elf gas to see the failure goes away.

[gdb/testsuite] Fix gdb.arch/amd64-tailcall-self.S
The test-case gdb.arch/amd64-tailcall-self.exp fails here:

...
like:
...
(gdb) file build/gdb/testsuite/outputs/gdb.arch/amd64-tailcall-self/\

The problem is that in amd64-tailcall-self.S, CU-relative references are
assigned .debug_info section relative values. [ This is similar to the
problem fixed by "Fix gdb.arch/amd64-entry-value-paramref.S". ]
Fix this by assigning CU-relative references instead.

This also enables the sve extension, since sve is a requirement of sve2.
Extra optional sve2 features are the bitperm, sm4, aes, and sha3 extensions.
These are all given extra feature flags, "bitperm", "sve2-sm4",
"sve2-aes", and "sve2-sha3" respectively.
The sm4, aes, and sha3 extensions are explicitly marked as sve2
extensions to distinguish them from the corresponding NEON extensions.
Rather than continue extending the current feature flag numbers, I used
some bits that have been skipped.

* config/tc-aarch64.c: Add command line architecture feature flags

[gdb/testsuite] Fix gdb.arch/amd64-entry-value-paramref.S
The file gdb.arch/amd64-entry-value-paramref.S contains a DIE for function
bar:
...
DIE29: .uleb128 0x2 # (DIE (0x29) DW_TAG_subprogram)
.ascii "bar\0" # DW_AT_name
.byte 0x1 # DW_AT_decl_file (gdb.arch/amd64-entry-value-paramref.cc)
.byte 0x15 # DW_AT_decl_line
.long DIE45 # DW_AT_type
.byte 0x1 # DW_AT_inline
...
which refers to DIE45:
...
DIE45: .uleb128 0x4 # (DIE (0x45) DW_TAG_base_type)
.byte 0x4 # DW_AT_byte_size
.byte 0x5 # DW_AT_encoding
.ascii "int\0" # DW_AT_name
...
using a form DW_FORM_ref4:
...
.uleb128 0x2 # (abbrev code)
.uleb128 0x2e # (TAG: DW_TAG_subprogram)
.byte 0x1 # DW_children_yes
...
.uleb128 0x49 # (DW_AT_type)
.uleb128 0x13 # (DW_FORM_ref4)
...
However, the DW_FORM_ref4 is a CU-relative reference, while using a label for
the value will result in a section-relative value.
So, if linked in object files contain dwarf info and are placed in the
.debug_info section before the compilation units generated from
amd64-entry-value-paramref.S, then the referenced type is at 0x108:
...
<1><108>: Abbrev Number: 4 (DW_TAG_base_type)
<109> DW_AT_byte_size : 4
<10a> DW_AT_encoding : 5 (signed)
<10b> DW_AT_name : int
...
but the reference will point to a non-existing DIE at 0x1cf:
...
<1><f0>: Abbrev Number: 2 (DW_TAG_subprogram)
<f1> DW_AT_name : bar
<f5> DW_AT_decl_file : 1
<f6> DW_AT_decl_line : 21
<f7> DW_AT_type : <0x1cf>
<fb> DW_AT_inline : 1 (inlined)
...
which happens to cause a GDB internal error described in PR23270 - "GDB
internal error: dwarf2read.c:18656: internal-error: could not find partial
DIE 0x1b7 in cache".
Fix the invalid DWARF by making the reference value CU-relative:
...
- .long DIE45 # DW_AT_type
+ .long DIE45 - .Ldebug_info0 # DW_AT_type
...
Tested on x86_64-linux.

When debugging a mixed Ada/C program using this scenario:
- set print frame-arguements all
- an Ada function named pck.call_me calls a C function named break_me
- you put a breakpoint in break_me and the program reaches this
breakpoint.
Now display the backtrace:
(gdb) bt
#0 break_me () at [...]
#1 0x000000000040243e in pck.call_me (
s={P_ARRAY = 0x7fffffffe21c, P_BOUNDS = 0x41e6e8}) at [...]
whereas we should expect:
(gdb) bt
#0 break_me () at [...]
#1 0x000000000040243e in pck.call_me (s="test") at [...]
The problem is that GDB prints the S parameter in the pck.call_me Ada
function using the current language, so the C one, because the program
is stopped in a C function, whereas it should use the pck.call_me frame
one. This behavior is ok when user manually changes the language but it's
not the right one when language is auto.
This patch fixes this problem so now when using auto language, all Ada
frame arguments are printed using Ada like syntax when the frame is part
of Ada code, even if the program is stopped in a frame using a different
language.
If the user explicitly sets a language (using "set language ...") then
no change here, all the Ada frame arguments are printed using this
language.

Fix style bug when paging
Philippe pointed out a styling bug that would occur in some conditions
when paging:
https://sourceware.org/ml/gdb-patches/2019-04/msg00101.html
I was finally able to reproduce this, and this patch fixes the bug.
The problem occurred when text overflowed the line, causing a
pagination prompt, but when no wrap column had been set. In this
case, the current style was reset to show the prompt, but then not
reset back to the previously applied style before emitting the rest of
the line.
The fix is to record the applied style in this case, and re-apply it
afterward -- but only if the pager prompt was emitted, something that
the existing style.exp pointed out on the first, more naive, version
of the patch.
Tested on x86-64 Fedora 29.

Correctly handle non-C-style arrays in c_get_string
A user here noticed that the Python Value.string method did not work
for Ada arrays. I tracked this down to an oddity in value_as_address
-- namely, it calls coerce_array, but that function will not force
array coercion when the language has c_style_arrays=false, as Ada
does.
This patch fixes the problem by changing c_get_string so that arrays
take the "in GDB's memory" branch. The actual patch is somewhat more
complicated than you might think, because the caller can request more
array elements than the type allows. This is normal when the type is
using the C struct hack.
Tested on x86-64 Fedora 29.

Change ptype/o to print bit offset
Consider this short C example:
struct inner
{
unsigned x;
unsigned y : 3;
unsigned z : 3;
};
struct outer
{
unsigned char o : 3;
struct inner i __attribute__ ((packed));
};
When I use "ptype/o" on this, I get:
(gdb) ptype/o struct outer
/* offset | size */ type = struct outer {
/* 0: 5 | 1 */ unsigned char o : 3;
/* XXX 5-bit hole */
/* 1 | 8 */ struct inner {
/* 1 | 4 */ unsigned int x;
/* 5:29 | 4 */ unsigned int y : 3;
/* 5:26 | 4 */ unsigned int z : 3;
/* XXX 2-bit padding */
/* XXX 3-byte padding */
/* total size (bytes): 8 */
} i;
/* total size (bytes): 9 */
}
In the location of "o" ("0: 5"), the "5" means "there are 5 bits left
relative to the size of the underlying type.
I find this very difficult to follow. On irc, Sergio said that this
choice came because it is what pahole does. However, I think it's not
very useful, and maybe is just an artifact of the way that
DW_AT_bit_offset was defined in DWARF 3.
This patch changes ptype/o to print the offset of a bitfield in a more
natural way, that is, using the bit number according to the platform's
bit numbering.
With this patch, the output is now:
(gdb) ptype/o struct outer
/* offset | size */ type = struct outer {
/* 0: 0 | 1 */ unsigned char o : 3;
/* XXX 5-bit hole */
/* 1 | 8 */ struct inner {
/* 1 | 4 */ unsigned int x;
/* 5: 0 | 4 */ unsigned int y : 3;
/* 5: 3 | 4 */ unsigned int z : 3;
/* XXX 2-bit padding */
/* XXX 3-byte padding */
/* total size (bytes): 8 */
} i;
/* total size (bytes): 9 */
}
This is better, IMO, because now the "offset" of a bitfield is
consistent with the offset of an ordinary member, referring to its
offset from the start of the structure.

Fix ptype/o comment formatting
I noticed that ptype/o will print:
/* 3: 3 | 1 */ signed char a4 : 2;
/* XXX 3-bit hole */
That is, "*/" at the end of the "hole" message does not line up with
the other comment ends. I thought it would be a bit nicer if this did
line up, so I fixed it. Then, to my surprise, I found that I could
not make ptype-offsets.exp fail.
I still am not sure why it doesn't fail, but changing the tests to use
string_to_regexp and changing the quoting helped. This in turn showed
that some of the existing test cases were wrong, so I've also updated
them here.

gas/elf dwarf2 tests
Make them work for tile, by using ".quad 0" as the simulated
instruction and doubling size of aligns. The larger aligns tripped
over riscv alignment handling, fixed by adding -mno-relax there.
Also disable link-relax for avr, pru and xtensa, allowing these
targets to pass these tests. With link-time relaxation enabled,
these targets emit alignment relocations rather than aligning at
assembly time. This means the assembler doesn't see a change in PC
when it is expected over an alignment frag and thus view numbers are
calculated incorrectly.

xfail locview tests on mep that use complex relocs for view numbers
Expressions that compute view numbers that aren't simplified early
enough to a constant end up being selected for representation as
complex relocations, enabled on mep-* targets.
It would be possible to recognize such expressions, that can resolve
to constants, but this problem was hit before, in preexisting tests,
so xfail the new hits similarly.
The new hits were caused by yesterday's patch to dwarf2dbg.c: views in
the beginning of subsections are now computed later, based on the

[gdb/testsuite] Fix ls_host return in index-cache.exp
When adding a debug print here in index-cache.exp:
...
proc_with_prefix test_cache_disabled { cache_dir } {
lassign [ls_host $cache_dir] ret files_before
+ puts "before: '$files_before'"
+ exit
...
we have:
...
files_before: ''
...
When further adding:
...
proc_with_prefix test_cache_disabled { cache_dir } {
+ exec touch $cache_dir/foo.1 $cache_dir/foo.2 $cache_dir/foo.3
...
we have:
...
files_before: 'foo.1'
...
while we're expecting file_before to contain foo.[123].
Fix this by making the return statement in ls_host return a list rather than a
string (in accordance with the ls_host documentation), after which we have:
...
files_before: 'foo.1 foo.2 foo.3'
...
Tested on x86_64-linux.

[gdb/testsuite] Fix .debug_aranges in watch-loc.c
When running gdb.dlang/watch-loc.exp with target board cc-with-debug-names, we
run into:
...
FAIL: gdb.dlang/watch-loc.exp: disassemble _Dmain (GDB internal error)
...
in more detail:
...
(gdb) disassemble _Dmain
gdb/dwarf2read.c:5293: internal-error: \
compunit_symtab* dw2_find_pc_sect_compunit_symtab(objfile*, \
bound_minimal_symbol, CORE_ADDR, obj_section*, int): \
Assertion `result != NULL' failed.
...
The problem is that the .debug_aranges section in watch-loc.c contains a
debug_info_offset which is set to 0:
...
asm (
" .pushsection .debug_aranges,\"\",%progbits\n"
" .4byte .Laranges_end - .Laranges_start\n"
".Laranges_start:\n"
" .2byte 0x2\n"
" .4byte 0\n"
...
while the compilation unit at offset 0 in the .debug_section in the executable
is in fact not the compilation unit generated from watch-loc-dw.S.
[ Note: this is a non-trivial test-case. The file watch-loc-dw.S contains a
.debug_info section, but not an .debug_aranges section or any actual code.
The file watch-loc.c contains code and a .debug_aranges section, but no other
debug section. So, the intent for the .debug_aranges section in watch-loc.c
is to refer to a compilation unit in the .debug_info section in
watch-loc-dw.S. ]
This happens when linked in object files contain dwarf info and are placed in
the .debug_info section before the compilation units generated from
watch-loc.c and watch-loc-dw.S.
Fix this by defining the debug_info_offset field using a label .Lcu1_begin
that defines the start of an empty .debug_section compilation unit:
...
asm (
+ " .pushsection .debug_info,\"\",%progbits\n"
+ ".Lcu1_begin:"
+ " .popsection\n"
" .pushsection .debug_aranges,\"\",%progbits\n"
" .4byte .Laranges_end - .Laranges_start \n"
".Laranges_start:\n"
" .2byte 0x2\n"
- " .4byte 0\n"
+ " .4byte .Lcu1_begin\n"
...
which during linking merges with the start of the .debug_info section of
watch-loc-dw.S.
Tested on x86_64-linux with native, cc-with-gdb-index and cc-with-debug-names.

[gdb/testsuite] Fix handling of DW_FORM_ref_addr in dwarf assembler
When running gdb.dwarf2/multidictionary.exp with target board cc-with-dwz and
current dwz, we run into a dwz abort:
...
gdb compile failed, gdb/contrib/cc-with-tweaks.sh: line 188: 11484 Aborted \
(core dumped) $DWZ "$output_file" > /dev/null 2>&1
UNTESTED: gdb.dwarf2/multidictionary.exp: multidictionary.exp
...
The dwz abort (PR dwz/24169) is caused by an invalid DW_FORM_ref_addr in the
multidictionary binary.
The multidictionary binary is build from multidictionary.S which is generated
using the dwarf assembler, and multidictionary.S contains dwarf for 3
compilation units.
In multidictionary0.o (generated from multidictionary.S), we find a concrete
formal parameter DIE:
...
<2><dc>: Abbrev Number: 4 (DW_TAG_formal_parameter)
<dd> DW_AT_abstract_origin: <0xa6>
...
referring to an abstract formal parameter DIE at 0xa6:
...
<2><a6>: Abbrev Number: 8 (DW_TAG_formal_parameter)
<a7> DW_AT_name : msg
<ab> DW_AT_type : <0x92>
...
but in the multidictionary binary the concrete formal parameter DIE is still
referring to 0xa6:
...
<2><1a3>: Abbrev Number: 4 (DW_TAG_formal_parameter)
<1a4> DW_AT_abstract_origin: <0xa6>
...
while the abstract formal parameter DIE has moved to 0x16d:
...
<2><16d>: Abbrev Number: 8 (DW_TAG_formal_parameter)
<16e> DW_AT_name : msg
<172> DW_AT_type : <0x159>
...
The concrete formal parameter DIE is specified in multidictionary.S like this:
...
.Llabel21:
.uleb128 4
.4byte .Llabel17 - .Lcu1_begin
...
The problem is that the .Lcu1_begin label is assumed to mark the start of the
.debug_info section in the executable, but in fact it marks the start of the
first compilation unit from multidictionary.S in the executable. Usually
these two entities are the same, but they are not when linked in object files
contain dwarf info and are placed in the .debug_info section before the
compilation units generated from multidictionary.S.
Fix this in the dwarf assembler by generating instead the label itself:
...
.Llabel21:
.uleb128 4
.4byte .Llabel17
...
resulting in a relocation in the object file:
...
Offset Info Type Sym. Value Sym. Name + Addend
0000000000dd 00040000000a R_X86_64_32 0000000000000000 .debug_info + a6
...
and resulting in the correct offset in the executable:
...
<2><1a3>: Abbrev Number: 4 (DW_TAG_formal_parameter)
<1a4> DW_AT_abstract_origin: <0x16d>
...
Tested on x86_64-linux with native and cc-with-dwz.

[LVu] base subseg head view on prev subseg's tail
Location views at borders between subsegments/subsections in the same
segment/section are computed as if each new subsegment/subsection
started with a forced view reset to zero, but the line number program
does not introduce resets that are not explicitly requested, so if a
subsegment ends at the same address another starts, the line number
program will have a continuity of views at the border address, whereas
the initial view number label in the latter subsegment will be
miscomputed as zero.
This patch delays the assignment of view expressions at subsegment
heads to the time of chaining the frags of subsegments into a single
segment, so that they are set based on the view at the end of the
previous subsegment in the same segment.
The line number program created for the test program had an
unnecessary DW_LNS_advance_pc at the end. This patch also arranges
for us not to emit it.

Fix incorrect use of 'is' operator for comparison in python/lib/gdb/command/prompt.py
The 'is' operator is not meant to be used for comparisons. It currently working
is an implementation detail of CPython. CPython 3.8 has added a SyntaxWarning
for this.

Don't derive partial_symbol from general_symbol_info
This patch partly reverts commit 8a6d42345 ("Change representation of
psymbol to flush out accessors"); specifically, it changes
partial_symbol to no longer derive from general_symbol_info.
The basic problem here is that the bcache compares objects bitwise,
and this change made it less likely that the relevant fields in the
psymbol would be fully initialized. This could be seen by running a
test under valgrind on the Fedora-i686 buildbot.
I considered a simpler patch, namely just zeroing the psymbol's
"value" field in add_psymbol_to_bcache. However, it wasn't clear to
me that this memset could not then be optimized away by the compiler.
Regression tested by the buildbot. I think this should go in 8.3 as
well.

m32c padding with nops
m32c_md_end attempted to pad out a code section with nops, but this
was just plain wrong in many ways:
- The padding didn't happen at all if the last section emitted wasn't
a code section.
- The padding went to the wrong place if subsections were used, and
the last subseg used wasn't the highest numbered subseg.
- Padding wasn't added to all code sections.
- If the last section was empty, it was padded to 4 bytes.
- The padding didn't go to a 4-byte alignment boundary, instead it
effectively made the last instruction 4 bytes in size.
- The padding didn't take into account that code sections may have
contents other than machine instructions.
So, rip it out and handle nop padding properly, also fixing .align
.balign/.p2align in the middle of code.

PR24511, nm should not mark symbols in .init_array as "t"
This patch restricts the section names matched in coff_section_type,
a function that translates section names to symbol type, and arranges
to translate section flags to symbol type before looking at names.
The latter change resulted in various test failures due to improper
section flags being used in tests, and by the plugin support, so fix
that too.
The new test fails on many ELF targets that lack .init/fini_array
in their scripts. I've just xfailed those. pru-elf oddly defines
__init_array_begin rather than __init_array_start. I've left that
target as a FAIL, and pj-elf too which reports an error for undefined
weak symbols.

Fix cast of character to enum type in Ada
An internal bug report points out that, when a global character enum
type is used, casting fails, like:
(gdb) print global_char_enum'('F')
$1 = 70
The bug here turns out to be that enumerators are qualified, so for
example the mangled name might be "pck__QU48", rather than "QU48".
This patch fixes the problem by only examining the suffix of the
enumerator. This is ok because the type is already known, and because
the mangling scheme ensures that there won't be clashes.

This changeset defines _WIN32_WINNT to at least 0x0501, the level
of Windows XP, unless defined to a higher level, in a single
place. It then removes all the overrides of _WIN32_WINNT in
individual files as no longer needed. Doing this also solves
compilation of windows-nat.c with mingw.org's MinGW, as that

Fix lookup of separate debug file on MS-Windows.
If you put the separate debug file in a global debug directory, GDB on
MS-Windows would fail to find it. This happens because we obtain the
directory to look up the debug file by concatenating the debug
directory name with the leading directories of the executable, and the
latter includes the drive letter on MS-Windows. So we get an invalid
file name like
d:/usr/lib/debug/d:/usr/bin/foo.debug
This commit fixes that by removing the colon of the drive letter,
thus producing
d:/usr/lib/debug/d/usr/bin/foo.debug

gdb/rust: Handle printing structures containing strings
When printing a rust structure that contains a string GDB can
currently fail to read the fields that define the string. This is
because GDB mistakenly treats a value that is the parent structure as
though it is the structure that defines the string, and then fails to
find the fields needed to extract a string.
The solution is to create a new value to represent the string field of
the parent value.

The dwarf4-gdb-index.exp board file includes cc-with-tweaks.exp, which uses
cc-with-tweaks.sh, which calls gdb-add-index.sh.
The gdb-add-index.sh script uses a gdb executable, defaulting to gdb:
...
GDB=${GDB:=gdb}
...
The cc-with-tweaks.sh script tries to ensure that the build gdb executable is
used by gdb-add-index.sh:
...
if [ -z "$GDB" ]
then
if [ -f ./gdb ]
then
GDB="./gdb -data-directory data-directory"
elif [ -f ../gdb ]
then
GDB="../gdb -data-directory ../data-directory"
elif [ -f ../../gdb ]
then
GDB="../../gdb -data-directory ../../data-directory"
else
echo "$myname: unable to find usable gdb" >&2
exit 1
fi
fi
...
So, if the current directory is build/gdb/testsuite, then a gdb executable
build/gdb/testsuite/../gdb will be used.
However, in the case of fullpath-expand.exp the test cd's into the sources:
...
set saved_pwd [pwd]
cd $srcdir
set err [gdb_compile "${subdir}/${srcfile} ${subdir}/${srcfile2}" $binfile \
executable {debug}]
cd $saved_pwd
...
and cc-with-tweaks.sh generates the "unable to find usable gdb" error.
The same error occurs if we use --target_board=cc-with-dwz instead (only in
this case we actually don't need gdb, we just need the GDB variable to be set
in cc-with-tweaks.sh, which arguably is a bug in cc-with-tweaks.sh).
Fix both errors in cc-with-tweaks.exp by generating a gdb script gdb.sh using
$GDB, $GDBFLAGS and $INTERNAL_GDBFLAGS and passing this script to
cc-with-tweaks.sh by setting env(GDB).

gdb/windows-nat.c: Get rid of main_thread_id global
This global is meant to point to the "main" thread of execution of
the program we are debugging. It is set when attaching to a process
or when receiving a CREATE_PROCESS_DEBUG_EVENT event. The theory at
the time was that this was also going to be the thread receiving
the EXIT_PROCESS_DEBUG_EVENT event.
Unfortunately, we have discovered since then that this is actually
not guaranteed. What this means in practice is that there is moderate
risk that main_thread_id refers to a thread which no longer exists.
This global is used in 3 situations:
- OUTPUT_DEBUG_STRING_EVENT
- LOAD_DLL_DEBUG_EVENT
- UNLOAD_DLL_DEBUG_EVENT
It's not clear why we would need to use the main_thread_id in those cases
instead of using the thread ID provided by the kernel events itself.
So this patch implements this approach, which then allows us to delete
the main_thread_id global.
gdb/testsuite:
* windows-nat.c (main_thread_id): Delete.
(handle_output_debug_string): Replace main_thread_id by
current_event.dwThreadId.
(fake_create_process): Likewise.
(get_windows_debug_event) <CREATE_PROCESS_DEBUG_EVENT>:
Do not set main_thread_id.
<LOAD_DLL_DEBUG_EVENT>: Replace main_thread_id by

(Windows) fix thr != nullptr assert failure in delete_thread_1
We have observed that GDB would randomly trip the following
assertion failure when debugging on Windows. When allowing
the program to run until the inferior exits, we occasionally see:
(gdb) cont
Continuing.
[Thread 48192.0xd100 exited with code 1]
[Thread 48192.0x10ad8 exited with code 1]
[Thread 48192.0x36e28 exited with code 0]
[Thread 48192.0x52be4 exited with code 0]

../../src/gdb/thread.c:453: internal-error: void delete_thread_1(thread_inf
o*, bool): Assertion `thr != nullptr' failed.
Running the same scenario with some additional traces enabled...
(gdb) set verbose
(gdb) set debugevents
... allows us to understand what the issue is. To understand, we need
to first look at the events received when starting the program, and
in particular which threads got created how. First, we get a
CREATE_PROCESS_DEBUG_EVENT for tid=0x442a8:
gdb: kernel event for pid=317536 tid=0x442a8 code=CREATE_PROCESS_DEBUG_EVENT)
Shortly after, we get some CREATE_THREAD_DEBUG_EVENT events,
one of them being for tid=0x4010c:
gdb: kernel event for pid=317536 tid=0x4010c code=CREATE_THREAD_DEBUG_EVENT)
Fast forward a bit of debugging, and we do a "cont" as above,
at which point the programs reaches the end, and the system reports
"exit" events. The first interesting one is the following:
gdb: kernel event for pid=317536 tid=0x442a8 code=EXIT_THREAD_DEBUG_EVENT)
This is reporting a thread-exit event for a thread whose tid
is the TID of what we call the "main thread". That's the thread
that was created when we received the CREATE_PROCESS_DEBUG_EVENT
notification, and whose TID is actually stored in a global variable
named main_thread_id. This is not something we expected, as
the assumption we made was that the main thread would exit last,
and we would be notified of it via an EXIT_PROCESS_DEBUG_EVENT.
But apparently, this is not always true, at least on Windows Server
2012 and 2016 where this issue has been observed happening randomly.
The consequence of the above notification is that we call
windows_delete_thread for that thread, which removes it from
our list of known threads.
And a little bit later, then we then get the EXIT_PROCESS_DEBUG_EVENT,
and we can see that the associated tid is not the main_thread_id,
but rather the tid of one of the threads that was created during
the lifetime of the program, in this case tid=0x4010c:
gdb: kernel event for pid=317536 tid=0x4010c code=EXIT_PROCESS_DEBUG_EVENT)
And the debug trace printed right after shows why we're crashing:
[Deleting Thread 317536.0x442a8]
We are trying to delete the thread whose tid=0x442a8, which is
the main_thread_id! As we have already deleted that thread before,
the search for it returns a nullptr, which then trips the assertion
check in delete_thread_1.
This commit fixes this issue. It ignores the open question of
what to do with the main_thread_id global, particularly after
that thread has been removed from our list of threads. This will
be dealt with as a separate patch, to allow cherry-picking
this patch into a release branch.
For now, we fix the code so as to avoid this crash.
gdb/ChangeLog:
* windows-nat.c (get_windows_debug_event) <EXIT_PROCESS_DEBUG_EVENT>:
Use current_event.dwThreadId instead of main_thread_id.

Fix "catch exception" with dynamic linking
When an Ada program is dynamically linked against libgnat, and when
one of the standard exceptions is used, the exception object may be
referenced by the main executable using a copy relocation.
In this situation, a "catch exception" for those exceptions will not
manage to stop. This happens because, under the hood, "catch
exception" creates an expression object that examines the object
addresses -- but in this case, the address will be incorrect.
This patch fixes the problem by arranging for these filter expressions
to examine all the relevant minimal symbols. This way, the object
from libgnat will be found as well.

Fix crash in dwarf2read.c with template parameters
PR c++/24470 concerns a crash in dwarf2read.c that occurs with a
particular test case.
The issue turns out to be that process_structure_scope will pass NULL
to symbol_symtab. This happens because new_symbol decided not to
create a symbol for the particular DIE.
This patch fixes the problem by finding another reasonably-appropriate
symtab to use instead; issuing a complaint if one cannot be found for
some reason.
As mentioned in the bug, I think there are other bugs here. For
example, when using "ptype" on the "l" object in the test case, I
think I would expect to see the template parameter. I didn't research
this too closely, since it seemed more important to fix the crash.
Tested on x86-64 Fedora 29.
I'd like to check this in to the 8.3 branch as well.

gdb/fortran: Print 'void' type in lower case
For a program compiled with gfortran the base type names are written
as lower cases in the DWARF, and so GDB will display them as lower
case. Additionally, in most places where GDB supplies its own type
names (for example all of the types defined in f-lang.c in
`build_fortran_types`), the type names are all lower case.
An exception to this is where GDB prints the void type for Fortran.
In this case GDB uses upper case.
I'm not aware of any reason why this type should merit special
attention, and it looks our of place when printing types, so this
commit changes from 'VOID' to 'void' to match all the other types.

* f-lang.c (build_fortran_types): Change name of void type to
lower case.

gdb/fortran: better types for components of complex numbers
Currently when using $_creal and $_cimag to access the components of a
complex number the types of these components will have C type names
'float', 'double', etc. This is because the components of a complex
number are not given type names in DWARF, so GDB has to pick some
suitable names, and currently we always use the C names.
This commit changes the type names used based on the language, so for
Fortran we will now use the Fortran float types, and so will get the
Fortran float type names 'real', 'real*8', etc.

gdb/fortran: Introduce fortran-operator.def file
Future commits will add more Fortran specific expression operators.
In preparation for these new operators, this commit adds a new
fortran-operator.def file similar to how GDB already has
ada-operator.def.
I've moved UNOP_KIND the Fortran specific operator I introduced in
commit 4d00f5d8f6c4 into this file, and renamed it to make it clearer
that the operator is Fortran specific. I've then updated the Fortran
exp_descriptor table (exp_descriptor_f) to use entirely Fortran
specific functions that now handle UNOP_FORTRAN_KIND (the new name for
UNOP_KIND).
There should be no visible changes for standard users after this
commit, though for developers, the output when 'set debug expression
1' is now better, before:

gdb: Introduce 'print max-depth' feature
Introduce a new print setting max-depth which can be set with 'set
print max-depth DEPTH'. The default value of DEPTH is 20, but this
can also be set to unlimited.
When GDB is printing a value containing nested structures GDB will
stop descending at depth DEPTH. Here is a small example:
typedef struct s1 { int a; } s1;
typedef struct s2 { s1 b; } s2;
typedef struct s3 { s2 c; } s3;
typedef struct s4 { s3 d; } s4;
s4 var = { { { { 3 } } } };
The following table shows how various depth settings affect printing
of 'var':
| Depth Setting | Result of 'p var' |
|---------------+--------------------------------|
| Unlimited | $1 = {d = {c = {b = {a = 3}}}} |
| 4 | $1 = {d = {c = {b = {a = 3}}}} |
| 3 | $1 = {d = {c = {b = {...}}}} |
| 2 | $1 = {d = {c = {...}}} |
| 1 | $1 = {d = {...}} |
| 0 | $1 = {...} |
Only structures, unions, and arrays are replaced in this way, scalars
and strings are not replaced.
The replacement is counted from the level at which you print, not from
the top level of the structure. So, consider the above example and
this GDB session:
(gdb) set print max-depth 2
(gdb) p var
$1 = {d = {c = {...}}}
(gdb) p var.d
$2 = {c = {b = {...}}}
(gdb) p var.d.c
$3 = {b = {a = 3}}
Setting the max-depth to 2 doesn't prevent the user from exploring
deeper into 'var' by asking for specific sub-fields to be printed.
The motivation behind this feature is to try and give the user more
control over how much is printed when examining large, complex data
structures.
The default max-depth of 20 means that there is a change in GDB's
default behaviour. Someone printing a data structure with 20 levels
of nesting will now see '{...}' instead of their data, they would need
to adjust the max depth, or call print again naming a specific field
in order to dig deeper into their data structure. If this is
considered a problem then we could increase the default, or even make
the default unlimited.
This commit relies on the previous commit, which added a new field to
the language structure, this new field was a string that contained the
pattern that should be used when a structure/union/array is replaced
in the output, this allows languages to use a syntax that is more
appropriate, mostly this will be selecting the correct types of
bracket '(...)' or '{...}', both of which are currently in use.
This commit should have no impact on MI output, expressions are
printed through the MI using -var-create and then -var-list-children.
As each use of -var-list-children only ever displays a single level of
an expression then the max-depth setting will have no impact.
This commit also adds the max-depth mechanism to the scripting
language pretty printers following basically the same rules as for the
built in value printing.
One quirk is that when printing a value using the display hint 'map',
if the keys of the map are structs then GDB will hide the keys one
depth level after it hides the values, this ensures that GDB produces
output like this:
$1 = map_object = {[{key1}] = {...}, [{key2}] = {...}}
Instead of this less helpful output:
$1 = map_object = {[{...}] = {...}, [{...}] = {...}}
This is covered by the new tests in gdb.python/py-nested-maps.exp.

gdb: Introduce new language field la_is_string_type_p
This commit is preparation work for the next commit, and by itself
makes no user visible change to GDB. I've split this work into a
separate commit in order to make code review easier.
This commit adds a new field 'la_is_string_type_p' to the language
struct, this predicate will return true if a type is a string type for
the given language.
Some languages already have a "is this a string" predicate that I was
able to reuse, while for other languages I've had to add a new
predicate. In this case I took inspiration from the value printing
code for that language - what different conditions would result in
printing something as a string.
A default "is this a string" method has also been added that looks for
TYPE_CODE_STRING, this is the fallback I've used for a couple of
languages.
In this commit I add the new field and initialise it for each
language, however at this stage the new field is never used.

gdb/ada: Update some predicate functions to return bool
A later commit would like to make use of a pointer to the function
ada_is_string_type, however, this will require the function to return
a bool (so the signature matches).
As the ada_is_string_type is a predicate function, and its return
value is only ever used as either true or false, then this commit
updates the function to return a bool.
As a consequence ada_is_character_type needs to change too.
There should be no user visible changes after this commit.

[gdb/testsuite] Fix regexp in skip_opencl_tests
When running gdb-caching-proc.exp, if skip_opencl_tests fails like this:
...
(gdb) run
Starting program: \
build/gdb/testsuite/outputs/gdb.base/gdb-caching-proc/opencltest13530.x
CHK_ERR (clGetPlatformIDs (1, &platform, NULL), -1001)

...
then this regexp in skip_opencl_tests fails to match:
...
-re ".*$inferior_exited_re code.*${gdb_prompt} $" {
...
so instead we hit the default clause after a 30 seconds timeout. With the
iteration count set at 10, we end up taking 6 minutes to run this test-case.
Fix this by adding the missing "with" in the regexp, bring back the runtime to
half a minute.

Have 'thread|frame apply' style their output.
'thread|frame apply CMD' launches CMD so that CMD output goes to a string_file.
This patch ensures that string_file for such CMD output contains
style escape sequences that 'thread|frame apply' will later on
output on the real terminal, so as to have CMD output properly styled.
The idea is to have the class ui_file having overridable methods
to indicate that the output to this ui_file should be done using
'terminal' behaviour such as styling.
Then these methods are overriden in string_file so that a specially
constructed string_file will get output with style escape sequences.
After this patch, the output of CMD by thread|frame apply CMD is styled
similarly as when CMD is launched directly.
Note that string_file (term_out true) could also support wrapping,
but this is not done (yet?).
Tested on debian/amd64.

Implement show | set may-call-functions [on|off]
Inferior function calls are powerful but might lead to undesired
results such as crashes when calling nested functions (frequently
used in particular in Ada).
This implements a GDB setting to disable calling inferior functions.
Note: the idea is that if/when the 'slash command' patch is pushed,
that this setting can be changed e.g. by using the shortcut /c.
This is version 2 of the patch. It handles all the received comments,
mostly replace 'can-call' by 'may-call', and avoid using
'inferior function call' in factor of 'calling function in the program'.

c++/24367: Infinite recursion of typedef substitution
This bug finds another usage where we end up segfaulting while
normalizing user input. inspect_type and replace_type recurse,
attempting to substitute the "real" symbol name for the typedef name.
However, since the both these names are the same, they keep calling
each other until the stack overflows.
A simple reproducer for it is given by
typedef struct foo foo;
int qux (foo *f) { return 0; }
(gdb) b qux(foo*)
Segmentation fault
inspect_type already contains some special handling to prevent a
similar situation from occurring with namespaces. I wonder, however,
whether we need be so pedantic about the exact nature of the substitution.
This patch implements this rather more aggressive assumption that these
substitutions should be avoided whenever the replacement symbol's name is
exactly the same as the one we're trying to substitute. [In the above
example, we're trying to substitute the tyepdef named "foo" with the symbol
named "foo" (a struct).]

Fix memory leak in exception code
PR gdb/24475 concerns a memory leak coming from gdb's exception
handling code.
The leak occurs because throw_exception_sjlj does not arrange to
destroy the exception object it is passed. However, because
gdb_exception has a destructor, it's undefined to longjmp in this
situation.
This patch fixes the problem by avoiding the need to run any
destructors in gdb_rl_callback_handler, by making the gdb_exception
"static".

This changes this code to run any destructors in inner scopes, and to

Implement dump of mappings with ELF headers by gcore
This patch has a long story, but it all started back in 2015, with
commit df8411da087dc05481926f4c4a82deabc5bc3859 ("Implement support
for checking /proc/PID/coredump_filter"). The purpose of that commit
was to bring GDB's corefile generation closer to what the Linux kernel
does. However, back then, I did not implement the full support for
the dumping of memory mappings containing ELF headers (like mappings
of DSOs or executables). These mappings were being dumped most of
time, though, because the default value of /proc/PID/coredump_filter
is 0x33, which would cause anonymous private mappings (DSOs/executable
code mappings have this type) to be dumped. Well, until something
happened on binutils...
A while ago, I noticed something strange was happening with one of our
local testcases on Fedora GDB: it was failing due to some strange
build-id problem. On Fedora GDB, we (unfortunately) carry a bunch of
"local" patches, and some of these patches actually extend upstream's
build-id support in order to generate more useful information for the
user of a Fedora system (for example, when the user loads a corefile
into GDB, we detect whether the executable that generated that
corefile is present, and if it's not we issue a warning suggesting
that it should be installed, while also providing the build-id of the
executable). A while ago, Fedora GDB stopped printing those warnings.
I wanted to investigate this right away, and spent some time trying to
determine what was going on, but other things happened and I got
sidetracked. Meanwhile, the bug started to be noticed by some of our
users, and its priority started changing. Then, someone on IRC also
mentioned the problem, and when I tried helping him, I noticed he
wasn't running Fedora. Hm... So maybe the bug was *also* present
upstream.
After "some" time investigating, and with a lot of help from Keith and
others, I was finally able to determine that yes, the bug is also
present upstream, and that even though it started with a change in ld,
it is indeed a GDB issue.
So, as I said, the problem started with binutils, more specifically
after the following commit was pushed:
commit f6aec96dce1ddbd8961a3aa8a2925db2021719bb
Author: H.J. Lu <hjl.tools@gmail.com>

ld: Add --enable-separate-code
This commit makes ld use "-z separate-code" by default on x86-64
machines. What this means is that code pages and data pages are now
separated in the binary, which is confusing GDB when it tries to decide
what to dump.
BTW, Fedora 28 binutils doesn't have this code, which means that
Fedora 28 GDB doesn't have the problem. From Fedora 29 on, binutils
was rebased and incorporated the commit above, which started causing
Fedora GDB to fail.
Anyway, the first thing I tried was to pass "-z max-page-size" and
specify a bigger page size (I saw a patch that did this and was
proposed to Linux, so I thought it might help). Obviously, this
didn't work, because the real "problem" is that ld will always use
separate pages for code and data. So I decided to look into how GDB
dumped the pages, and that's where I found the real issue.
What happens is that, because of "-z separate-code", the first two pages
of the ELF binary are (from /proc/PID/smaps):

Notice how we have "Anonymous" data mapped into the page. This will be
important.
So, the way GDB decides which pages it should dump has been revamped
by my patch in 2015, and now it takes the contents of
/proc/PID/coredump_filter into account. The default value for Linux
is 0x33, which means:
Dump anonymous private, anonymous shared, ELF headers and HugeTLB
private pages.
Or:
filter_flags filterflags = (COREFILTER_ANON_PRIVATE
| COREFILTER_ANON_SHARED
| COREFILTER_ELF_HEADERS
| COREFILTER_HUGETLB_PRIVATE);
Now, it is important to keep in mind that GDB doesn't always have *all*
of the necessary information to exactly determine the type of a page, so
the whole algorithm is based on heuristics (you can take a look at
linux-tdep.c:dump_mapping_p and
linux-tdep.c:linux_find_memory_regions_full for more info).
Before the patch to make ld use "-z separate-code", the (single) page
containing data and code was being flagged as an anonymous (due to the
non-zero "Anonymous:" field) private (due to the "r-xp" permission),
which means that it was being dumped into the corefile. That's why it
was working fine.
Now, as you can imagine, when "-z separate-code" is used, the *data*
page (which is where the ELF notes are, including the build-id one) now
doesn't have any "Anonymous:" mapping, so the heuristic is flagging it
as file-backed private, which is *not* dumped by default.
The next question I had to answer was: how come a corefile generated by
the Linux kernel was correct? Well, the answer is that GDB, unlike
Linux, doesn't actually implement the COREFILTER_ELF_HEADERS support.
On Linux, even though the data page is also treated as a file-backed
private mapping, it is also checked to see if there are any ELF headers
in the page, and then, because we *do* have ELF headers there, it is
dumped.
So, after more time trying to think of ways to fix this, I was able to
implement an algorithm that reads the first few bytes of the memory
mapping being processed, and checks to see if the ELF magic code is
present. This is basically what Linux does as well, except that, if
it finds the ELF magic code, it just dumps one page to the corefile,
whereas GDB will dump the whole mapping. But I don't think that's a
big issue, to be honest.
It's also important to explain that we *only* perform the ELF magic
code check if:
- The algorithm has decided *not* to dump the mapping so far, and;
- The mapping is private, and;
- The mapping's offset is zero, and;
- The user has requested us to dump mappings with ELF headers.
IOW, we're not going to blindly check every mapping.
As for the testcase, I struggled even more trying to write it. Since
our build-id support on upstream GDB is not very extensive, it's not
really possible to determine whether a corefile contains build-id
information or not just by using GDB. So, after thinking a lot about
the problem, I decided to rely on an external tool, eu-unstrip, in
order to verify whether the dump was successful. I verified the test
here on my machine, and everything seems to work as expected (i.e., it
fails without the patch, and works with the patch applied). We are
working hard to upstream our "local" Fedora GDB patches, and we intend
to submit our build-id extension patches "soon", so hopefully we'll be
able to use GDB itself to perform this verification.
I built and regtested this on the BuildBot, and no problems were
found.

Detect invalid length field in debug frame FDE header.
GDB was failing to catch cases where a corrupt ELF or core file
contained an invalid length value in a Dwarf debug frame FDE header.
It was checking for buffer overflow but not cases where the length was
negative or caused pointer wrap-around.
In addition to the additional validity check, this patch cleans up the
multiple signed/unsigned conversions on the length field so that an
unsigned representation is used consistently throughout.
This patch fixes CVE-2017-9778 and PR gdb/21600.

[BFD, AArch64] Improve bti/pac plts.
This patch aims to improve the definitions of BTI and PAC based PLTs.
The following changes are made:
* PLT0 does not need PAC instructions since the PLTGOT[2] (and PLTGOT[1])
are readonly so they cannot be corrupted at runtime. Thus both PAC plt0
and BTI+PAC plt0 are removed and we can use basic plt0 and BTI plt0
instead, respectively.
* We can remove the extra padding nops when we add the new bti instructions.
BTI plt0 and BTI TLSDESC plt are updated.
* For better performance PLTn could be padded to 24bytes. Both BTI pltn and

Speed up locview resolution with relaxable frags
Targets such as xtensa incur a much higher overhead to resolve
location view numbers than e.g. x86, because the expressions used to
compute view numbers cannot be resolved soon enough.
Each view number is computed by incrementing the previous view, if
they are both at the same address, or by resetting it to zero
otherwise. If PV is the previous view number, PL is its location, and
NL is the location of the next view, its number is computed by
evaluating NV = !(NL > PL) * (PV + 1).
set_or_check_view uses resolve_expression to decide whether portions
of this expression can be simplified to constants. The (NL > PL)
subexpression is one that can often be resolved to a constant,
breaking chains of view number computations at instructions of nonzero
length, but not after alignment that might be unnecessary.
Alas, when nearly every frag ends with a relaxable instruction,
frag_offset_fixed_p will correctly fail to determine a known offset
between two unresolved addresses in neighboring frags, so the
unresolved symbolic operation will be constructed and used in the
computation of most view numbers. This results in very deep
expressions.
As view numbers get referenced in location view lists, each operand in
the list goes through symbol_clone_if_forward_ref, which recurses on
every subexpression. If each view number were to be referenced, this
would exhibit O(n^2) behavior, where n is the depth of the view number
expressions, i.e., the length of view number sequences without an
early resolution that cuts the expression short.
This patch enables address compares used by view numbering to be
resolved even when exact offsets are not known, using new logic to
determine when the location either remained the same or changed for
sure, even with the possibility of relaxation. This enables most view
number expressions to be resolved with a small, reasonable depth.

Use better test for usable compiler in ld testsuite.
The ld testsuite includes numerous tests that depend on being able to
compile and link programs with the C compiler. Some of these tests
use [which $CC] to check for the presence of the compiler before
proceeding with the test, but run_ld_link_exec_tests and run_cc_link_tests
give ERRORs if compilation fails. Also, even if $CC is defined and present,
it may not be usable due to missing libraries, etc.
This patch adds a new procedure check_compiler_available that attempts
to build an empty program and caches the result. Uses of [which $CC]
are replaced with calls to this procedure, and run_ld_link_exec_tests
and run_cc_link_tests now also guard attempts to use $CC.

Use "pulongest" on aarch64-tdep.c:aarch64_gdbarch_init
While trying to build GDB on i686, I found the following error:
In file included from ../../gdb/common/common-defs.h:105,
from ../../gdb/defs.h:28,
from ../../gdb/aarch64-tdep.c:21:
../../gdb/aarch64-tdep.c: In function 'gdbarch* aarch64_gdbarch_init(gdbarch_info, gdbarch_list*)':
../../gdb/aarch64-tdep.c:3176:43: error: format '%ld' expects argument of type 'long int', but argument 4 has type 'uint64_t' {aka 'long long unsigned int'} [-Werror=format=]

3176 | internal_error (__FILE__, __LINE__, _("VQ out of bounds: %ld (max %d)"),

| |
| long int
| %lld
This happens because aarch64-tdep.c:aarch64_gdbarch_init prints a
"uint64_t" variable using "%ld". This patch fixes the build by using
"pulongest" instead. As explained in a similar fix (commit
495143533ad95369811391c6e3c6dadd69d7dd67), this should be safe because
if aarch64-tdep.c is included in the build, then ULONGEST must be a
64-bit type.

2019-04-24 Sergio Durigan Junior <sergiodj@redhat.com>
* aarch64-tdep.c (aarch64_gdbarch_init): Use "pulongest" to print
"vq".

Fix passing of struct with bitfields on x86-64
Commit 4aa866af ("Fix AMD64 return value ABI in expression
evaluation") introduced a regression when calling a function with a
structure that contains bitfields.
Because the caller of amd64_has_unaligned_fields handles bitfields
already, it seemed to me that the simplest fix was to ignore bitfields
here.

resolve_symbol_value vs. .loc view resolution
In most cases we don't want expression symbols, such as that created
for an expression like "symbol + (1f - .)", resolved down to a
constant. Instead we'd like to leave the expression as "symbol +
constant" once the "1f - ." part has been resolved, and let the
backend decide whether "symbol" can be reduced further.
However, that doesn't work when trying to resolve .loc view symbols
early. We get expression symbols left as an O_symbol expression
pointing at an absolute symbol, and marked as sy_flags.sy_resolved.
That wouldn't really be a problem, but when one of those expression
symbols is used in further .loc view expressions, its value is taken
as zero.
This patch fixes the symbol value mistake, and stops creation of
O_symbol expression symbols pointing to absolute symbols. Either of
these fixes would cure the .loc view usage.
PR 24444
* symbols.c (resolve_symbol_value): When handling symbols
marked as sy_flags.resolved, return correct value for the
case of expression symbols left as an O_symbol expression.
Merge O_symbol code handling undefined and common symbols with
code handling special cases of expression symbols. Use
seg_left to test for undefined and common symbols. Don't
leave an O_symbol expression when X_add_symbol resolves to
the absolute_section. Init final_val later.

gdb/m32c: Use default gdbarch methods where possible
Make use of the default gdbarch methods for gdbarch_dummy_id,

gdb/nds32: Use type_align instead of nds32_type_align
The general type_align method should be a suitable alternative to
nds32_type_align, so switch to use that.
The only change this will introduce is related to static fields in a
struct or union, the existing code doesn't take account of static
fields when computing the alignment for structs of unions, though this
is probably a bug - which would probably be exposed by the test case
gdb.cp/many-args.exp, though I don't have any way to test this target
right now.

gdb/arm: Use type_align instead of arm_type_align
Replaces use of arm_type_align with common type_align function.
Doing this fixes a bug in arm_type_align where static fields are
considered as part of the alignment calculation of a struct, which
results in arguments passed on the stack being misaligned, this bug
was causing a failure in gdb.cp/many-args.exp.
Part of the old arm_type_align is retained and used as the gdbarch
type align callback in order to correctly align vectors.

[gdb/testsuite] Fix gdb.btrace/reconnect.exp with native-gdbserver
When running gdb.btrace/reconnect.exp with native-gdbserver, we run into:

due to the fact that we're trying to match:

[gdb/contrib] Remove superfluous .alt file after dwz invocation in cc-with-tweaks.sh
The -m option of cc-with-tweaks.sh sets want_multi to true, invoking dwz like
this:
...
elif [ "$want_multi" = true ]; then
cp $output_file ${output_file}.alt
$DWZ -m ${output_file}.dwz "$output_file" ${output_file}.alt \
> /dev/null 2>&1
fi
...
The problem that is being solved here, is that we want to test dwz in
multifile mode, which requires more than one input file, while we only have
(at the scope of cc-with-tweaks.sh) one executable. We handle this by copying
the executable and offering this as a second input (and using a copy has the
additional benefit that it maximally enables dwz transformation).
However, after the dwz invocation, the copy is no longer used, and the
presence of the file actually causes a test regression:
...
FAIL: gdb.base/jit-so.exp: test jit-reader-load filename completion
...
Fix this by removing the superflous copy after dwz invocation.
Tested on x86_64-linux.

Ubuntu/Debian defaults PIE to enabled. This causes the trace tests

solib-svr4: Pass down svr4_info as much as possible
While reviewing
https://sourceware.org/ml/gdb-patches/2019-04/msg00141.html
I noticed that we relied heavily on global state through the
get_svr4_info function, which uses current_program_space. I thought we
could improve this (make things more explicit and easier to follow) by
- Making get_svr4_info accept a program_space parameter, making it
return the SVR4 info for that program space.
- Passing down the svr4_info object from callers as much as possible.
This means looking up the svr4_info for the appropriate program space at
the entry points of the solib-svr4.c file and passing it down. For now,
these entry points (most of them are "methods" of svr4_so_ops) rely on
current_program_space, but we can later try to change the target_so_ops
interface to pass down the program space.
gdb/ChangeLog:
* solib-svr4.c (get_svr4_info): Add pspace parameter.
(svr4_keep_data_in_core): Pass current_program_space to get_svr4_info.

(svr4_fetch_objfile_link_map): Pass objfile->pspace to

(svr4_in_dynsym_resolve_code): Pass current_program_space to
get_svr4_info.
(probes_table_htab_remove_objfile_probes): Pass objfile->pspace
to get_svr4_info.
(probes_table_remove_objfile_probes): Likewise.
(register_solib_event_probe): Add info parameter.
(solist_update_incremental): Pass info parameter down to
svr4_read_so_list.
(disable_probes_interface): Add info parameter.
(svr4_handle_solib_event): Pass current_program_space to

pass it down to svr4_create_probe_breakpoints.

Fix "nosharedlibrary + continue + shared lib event" crash
On systems that use the probes-based solib interface, GDB misbehaves
if you run the "nosharelibrary" command, continue execution, and then
the program hits the shared library event breakpoint. On my system it
aborts like this:
(gdb) nosharedlibrary
(gdb) c
Continuing.
pure virtual method called
terminate called without an active exception
Aborted (core dumped)
Though it's really undefined behavior territory, caused by deferencing
a dangling solib event probe pointer.
I've observed this by running "nosharedlibrary" when stopped at the
entry point, but it should happen at any other point, if the program
does a dlopen/dlclose after.
The fix is to discard an objfile's probes from the svr4 probes table
when an objfile is about to be released.
New test included, works with both native and gdbserver testing.
Valgrind log:
(gdb) starti
(gdb) nosharedlibrary
(gdb) c
Continuing.

lookup.address = address;
That line isn't necessary because hashing/comparison only looks at the

Fix GDB crash when registers cannot be modified.
This crash was detected when using GDB with the valgrind gdbserver.
To reproduce:
valgrind sleep 10000
In another window:
gdb
target remote | vgdb
p printf("make sleep print something\n")
=>
terminate called after throwing an instance of 'gdb_exception_error'
Aborted
The problem is that the valgrind gdbserver does not allow to change
registers when the inferior is blocked in a system call.
GDB then raises an exception. The exception causes the destructor
of
typedef std::unique_ptr<infcall_suspend_state, infcall_suspend_state_deleter>
infcall_suspend_state_up;
to be called. This destructor itself tries to restore the value of
the registers, and fails similarly. We must catch the exception in
the destructor to avoid crashing GDB.
If the destructor encounters a problem, no warning is produced if
there is an uncaught exception, as in this case, the user will already
be informed of a problem via this exception.
With this change, no crash anymore, and all the valgrind 3.15 tests
pass succesfully.

Print non-Ada unions without crashing
ada-lang.c is a bit too eager trying to decode unions in the Ada style
-- looking for discriminants and such. This causes crashes when
printing a non-Ada union in Ada mode, something that can easily happen
when printing a value from history or certain registers on AArch64.
This patch fixes the bug by changing ada-lang.c to only apply special
Ada treatment to types coming from an Ada CU. This in turn required a
couple of surprising changes.
First, some of the Ada code was already using HAVE_GNAT_AUX_INFO to
decide whether a type had already been fixed -- such types had
INIT_CPLUS_SPECIFIC called on them. This patch changes these spots to
use the "none" identifier instead.
This then required changing value_rtti_type to avoid changing the
language-specific object attached to an Ada type, which seems like a
good change regardless.
Tested on x86-64 Fedora 29.

[gdb] Handle vfork in thread with follow-fork-mode child
When debugging any of the testcases added by this commit, which do a
vfork in a thread with "set follow-fork-mode child" + "set
detach-on-fork on", we run into this assertion:
...
src/gdb/nat/x86-linux-dregs.c:146: internal-error: \
void x86_linux_update_debug_registers(lwp_info*): \
Assertion `lwp_is_stopped (lwp)' failed.
...
The assert is caused by the following: the vfork-child exit or exec
event is handled by handle_vfork_child_exec_or_exit, which calls
target_detach to detach from the vfork parent. During target_detach
we call linux_nat_target::detach, which:
#1 - stops all the threads
#2 - waits for all the threads to be stopped
#3 - detaches all the threads
However, during the second step we run into this code in
stop_wait_callback:
...
/* If this is a vfork parent, bail out, it is not going to report
any SIGSTOP until the vfork is done with. */
if (inf->vfork_child != NULL)
return 0;
...
and we don't wait for the threads to be stopped, which results in this
assert in x86_linux_update_debug_registers triggering during the third
step:
...
gdb_assert (lwp_is_stopped (lwp));
...
The fix is to reset the vfork parent's vfork_child field before
calling target_detach in handle_vfork_child_exec_or_exit. There's
already similar code for the other paths handled by
handle_vfork_child_exec_or_exit, so this commit refactors the code a
bit so that all paths share the same code.
The new tests cover both a vfork child exiting, and a vfork child
execing, since both cases would trigger the assertion.
The new testcases also exercise following the vfork children with "set
detach-on-fork off", since it doesn't seem to be tested anywhere.
Tested on x86_64-linux, using native and native-gdbserver.

Avoid crash in dwarf2_init_complex_target_type
After commit 35add35 ("gdb: Fix failure in gdb.base/complex-parts.exp
for x86-32"), dwarf2_init_complex_target_type can crash if "tt" is
nullptr. This patch avoids the problem by checking for this case.

gdbserver: Move remote_debug to a single place
A comment in debug.h (written in 2014) states: "We declare debug format
variables here, and debug_threads but no other debug content variables
(e.g., not remote_debug) because while this file is not currently used by
IPA it may be some day, and IPA may have its own set of debug content
variables".
This has resulted in remote_debug being declared in many .c/.h files
throughout gdbserver.
It would be much simplier to define it one place. The most logical place to
define it is in debug.h, surrounded by #define guards. If IPA is changed,
then at that point the variable can be moved elsewhere.

gdb/riscv: Allow breakpoints to be created at invalid addresses
Some testsuite cases (gdb.cp/nsalias.exp for example) construct dwarf2
debug info for fake functions to test that this debug info is handled
correctly.
We currently get an error trying to read from an invalid address while
creating breakpoints for these fake functions.
Other targets allow creating breakpoints on invalid addresses, and
only error when GDB actually tries to insert the breakpoints.
In order to make RISC-V behave in the same way as other targets, this
commit makes the failure to read memory during breakpoint creation
non-fatal, we then expect to see a failure when GDB tries to insert
the breakpoint, just like other targets.
Tested with a riscv64-linux native testsuite run.
gdb/ChangeLog:
* riscv-tdep.c (riscv_breakpoint_kind_from_pc): Hanndle case where
code read might fail, assume 4-byte breakpoint in that case.

Fix AMD64 return value ABI in expression evaluation
The AMD64 System V ABI specifies that when a function has a return type
classified as MEMORY, the caller provides space for the value and passes
the address to this space as the first argument to the function (before
even the "this" pointer). The classification of MEMORY is applied to
struct that are sufficiently large, or ones with unaligned fields.
The expression evaluator uses call_function_by_hand to call functions,
and the hand-built frame has to push arguments in a way that matches the
ABI of the called function. call_function_by_hand supports ABI-based
struct returns, based on the value of gdbarch_return_value, however on
AMD64 the implementation of the classifier incorrectly assumed that all
non-POD types (implemented as "all types with a base class") should be
classified as MEMORY and use the struct return.
This ABI mismatch resulted in issues when calling a function that returns
a class of size <16 bytes which has a base class, including issues such
as the "this" pointer being incorrect (as it was passed as the second
argument rather than the first).
This is now fixed by checking for field alignment rather than POD-ness,
and a testsuite is added to test expression evaluation for AMD64.
gdb/ChangeLog:
* amd64-tdep.c (amd64_classify_aggregate): Use cp_pass_by_reference
rather than a hand-rolled POD check when checking for forced MEMORY
classification.

[binutils, ARM, 16/16] Add support to VLDR and VSTR of system registers
GNU as' Arm backend assumes each mnemonic has a single entry in the instruction table but VLDR (system register) and VSTR (system register) are different instructions than VLDR and VSTR. It is thus necessary to add some form of demultiplexing in the parser. It starts by creating a new operand type OP_VLDR which indicate that the operand is either the existing OP_RVSD operand or a system register. The function parse_operands () then tries these two cases in order, calling the new parse_sys_vldr_vstr for the second case.
Since the encoding function is specified in the instruction table entry, it also need to have some sort of demultiplexing. This is done in do_vldr_vstr which either calls the existing do_neon_ldr_str () or calls the new do_t_vldr_vstr_sysreg ().
A new internal relocation is needed as well since the offset has a shorter range than in other Thumb coprocessor instructions. Disassembly also requires special care since VSTR (system register) reuse the STC encoding with the coprocessor number 15. Armv8.1-M Mainline ARM manual states that coprocessor 8, 14 and 15 are reserved for floating-point and MVE instructions a feature bit check is added if the coprocessor number is one of this value and we are trying to match a coprocessor instruction (eg. STC) to forbid the match.

[binutils, ARM, 15/16] Add support for VSCCLRM
Like for CLRM, this patch aims to share as much logic with the similar looking VLDM/VSTM. This is achieved by adding 2 new enumerator values in enum reg_list_els for the single-precision and double-precision variants of VSCCLRM and extending parse_vfp_reg_list () to deal with these types.
These behave like the existing REGLIST_VFP_S and REGLIST_VFP_D types with extra logic to expect VPR as the last element in the register list.
The function is algo augmented with a new partial_match parameter to indicate if any register other than VPR had already been parsed in the register list so as to not try parsing the second variant if that's the case and return the right error message.
The rest of the patch is the usual encoding function, new disassembler table entries and format specifier and parsing, encoding and disassembling tests.
It is worth mentioning that the new entry in the disassembler table was added in the coprocessor-related table despite VSCCLRM always being available even in FPU-less configurations. The main reason for this is that VSCCLRM also match VLDMIA entry and must thus be tried first but coprocessor entries are tried before T32 entries. It also makes sense because it is in the same encoding space as coprocessor and VFP instructions and is thus the natural place for someone to look for this instruction.
Note: Both variants of VSCCLRM support D16-D31 registers but Armv8.1-M Mainline overall does not. I have thus decided not to implement support for these registers in order to keep the code simpler. It can always be added later if needed.

[opcodes, ARM, 14/16] Add mode availability to coprocessor table entries
The coprocessor_opcodes table is used both to share commonalities in coprocessor-related instructions and to avoid duplication between Arm and Thumb mode. However, some instructions do have differences between Arm and Thumb. For instance, vldmia allows PC as base register in Arm mode but not in Thumb mode.
In that very case the distinction becomes necessary because the encoding with PC as base register is used in Thumb mode to denote a VSCCLRM. It is thus necessary to distinguish what is Arm or Thumb only from what is shared. This patch adds an extra field to the coprocessor_opcodes table entries to indicate what mode is a given instruction available in. The print_insn_coprocessor then uses that field to determine if an entry that matched the mark and value checked should be allowed to match or not given the current mode.
ChangeLog entry is as follows:

[binutils, ARM, 13/16] Add support for CLRM
Given the similarity between LDM/STM and CLRM register lists, most of the changes in this patch aim at sharing code between those two sets of instruction. Sharing is achieved both in parsing and encoding of those instructions.
In terms of parsing, parse_reg_list () is extended to take a type that describe what type of instruction is being parsed. The reg_list_els used for parse_vfp_reg_list () is reused for the type and that function is added an assert for the new REGLIST_CLRM and REGLIST_RN enumerators.
parse_reg_list () is then taught to accept APSR and reject SP and PC when parsing for a CLRM instruction. At last, caller of parse_reg_list () is updated accordingly and logic is added for the new OP_CLRMLST operand.
Encoding-wise, encode_thumb2_ldmstm () is reused to encode the variable bits of CLRM and is thus renamed encode_thumb2_multi (). A new do_io parameter is added to distinguish between LDM/STM and CLRM which guard all the LDM/STM specific code of the function.
Finally objdump is told how to disassemble CLRM, again reusing the logic to print the LDM/STM register list (format specifier 'm'). Tests are also added in the form of negative tests to check parsing and encoding/disassembling tests.

[GAS, ARM, 2/16] Add CLI extension support for Armv8.1-M Mainline
This patch implements the dsp, fp and fp.dp extensions for Armv8.1-M Mainline.
This patch also removes the fp-armv8 check from the half-precision move
instructions 'do_neon_movhf', as checking that the FP16 instructions extension
feature bit is enabled 'ARM_EXT2_FP16_INST' is enough.

[binutils, ARM, 1/16] Add support for Armv8.1-M Mainline CLI
The patch is straightforward, it does the following:
- support the new Tag_CPU_arch build attribute value, ie.:
+ declare the new value
+ update all the asserts forcing logic to be reviewed for new
architectures
+ create a corresponding bfd_mach_arm_8_1M_MAIN enumerator in bfd and
add mapping from Tag_CPU_arch to it
+ teach readelf about new Tag_CPU_arch value
- declare armv8.1-m.main as a supported architecture value
- define Armv8.1-M Mainline in terms of feature bits available
- tell objdump mapping from bfd_mach_arm_8_1M_MAIN enumerator to feature
bits available
- update architecture-specific logic in gas and bfd guarded by the
asserts mentioned above.
- tests for all the above

sim: Use host not target byte order for merging and splitting values
When using writes to memory through a struct to merge and extract
multi-word value, it is the endianness of the host, not the target
that affects which order the component words need to be written into
the structure.
Of the 5 functions adjusted here 4 of them are unused. The 5th,
JOINSIDF will soon be used by the or1k target.
For or1k, simulated on x86-64, this change fixes this function so that
the correct bytes are now returned.

Automatic makefile dependencies for generated ld/e*.c
This patch modifies genscripts.sh to emit dependency info along with
the generated emulation e*.c files. This is done by a new source_sh
function that records its arg to a file (.deps/e*.Tc), using the
function whenever a shell script is sourced. Entries in the file are

included by the Makefile.

gdb: Fix failure in gdb.base/complex-parts.exp for x86-32
The x86-32 ABI specifies 96-bit long double, this was causing a
failure on the test gdb.base/complex-parts.exp.
The problem is that GDB tries to find a builtin floating point type of
the correct size in order to reuse the name of that type as the name
for the components of the complex type being built.
Previously GDB was only aware of floating point types sized 32, 64, or
128 bits. This patch teaches GDB how to handle 96 bit floating point
type.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_init_complex_target_type): Handle complex
target types of size 96-bits, add some additional comments, and
check that the builtin type we found was the correct size.

gdb: Remove LANG_MAGIC
The language_defn structure has an la_magic field, this used to be
used as a basic check that the language_defn structure had the
expected layout - at least the end of the structure was where we
expected it to be.
This feature only really makes sense if we imagine GDB dynamically
loading language support from dynamic libraries, where a version
mismatch might cause problems.
However, in current GDB language support is statically built into GDB,
and since this commit:

Date: Thu Jul 20 18:28:01 2017 +0100
Make language_def O(1)
the existing (if pointless) check of the la_magic field was removed.
There now appears to be no use of the la_magic field, and I propose
that we delete it.
There should be no user visible changes after this commit.

This commit resolves a large number of failures in the test script
gdb.base/infcall-nested-structs.exp which were caused by GDB (for
RISC-V) incorrectly handling empty C++ structures when preparing
arguments for a dummy call, or collecting a return value.
The issue is further complicated in that there was a bug in GCC, such
that in some cases GCC would generate incorrect code when passing a
small structure that contained empty sub-structures. This was fixed
in GCC trunk on 5-March-2019, so in order to see the best results with
this patch you'll need a recent version of GCC.
Anything that used to work should continue to work after this patch,
regardless of GCC version being used.
The fix in this commit is that GDB now pays more attention to the
offset of fields within a structure when preparing arguments as in C++
an empty structure has a non-zero size, this is an example:
struct s1 { struct s2 { } empty; int f; };
We previously assumed that 'f' was at offset 0 inside type 's1',
however this is not the case in C++ as 's2' has size 1, and with
alignment 'f' is likely at some even bigger offset inside 's1'.
gdb/ChangeLog:
* riscv-tdep.c (riscv_call_arg_complex_float): Fix offset of first
component to 0.
(riscv_struct_info::riscv_struct_info): Initialise m_offsets
member.
(riscv_struct_info::analyse): New implementation using new
analyse_inner member function.
(riscv_struct_info::field_offset): New member function.
(riscv_struct_info::m_offsets): New member variable.
(riscv_struct_info::analyse_inner): New private member function,
takes the old implementation of riscv_struct_info::analyse but
extended to track field offsets.
(riscv_call_arg_struct): Update the struct folding special cases
to handle cases where empty C++ structs, which are non-zero
length, are found.
(riscv_arg_location): Initialise the length of each location, a
non-zero length now indicates the location is in use.
(riscv_push_dummy_call): Allow for the first location having a
non-zero offset when setting up arguments.
(riscv_return_value): Likewise, but for return values.

Make "msg" const in internal_vproblem
I noticed that the "msg" variable in internal_vproblem could be
"const". This seems like an improvement because it can wind up in
rodata.

ld: Add --no-print-map-discarded option
Add a new option to disable the listing of discarded sections
in map file output. The use case stems from a large application
built with -ffunction-sections --gc-sections where the list of
discarded sections blows up the map file output. The default
behaviour remains to print discarded sections, but the new option
allows us to disable it.

[gdb/testsuite] Add cc-with-dwz.exp and cc-with-dwz-m.exp
We can use CC_WITH_TWEAKS_FLAGS when cd-ing into the gdb build subdir and
invoking make check:
...
$ cd $objdir/gdb
$ make check \
RUNTESTFLAGS='--target_board=cc-with-tweaks' \
CC_WITH_TWEAKS_FLAGS='-z'
...
But when cd-ing into the top-level build dir and invoking make check-gdb
instead:
...
$ cd $objdir
$ make check-gdb \
RUNTESTFLAGS='--target_board=cc-with-tweaks' \
CC_WITH_TWEAKS_FLAGS='-z'
...
using CC_WITH_TWEAKS_FLAGS has no effect, because CC_WITH_TWEAKS_FLAGS is not
passed down from the top level Makefile.
Add cc-with-dwz.exp and cc-with-dwz-m.exp, that don't require
CC_WITH_TWEAKS_FLAGS to be set in the make invocation, allowing us to run these
test configurations from the toplevel build dir:
...
$ cd $objdir
$ make check-gdb \
RUNTESTFLAGS='--target_board=cc-with-dwz'
...

AArch64: When DF_BIND_NOW don't use TLSDESC GOT value.
When using DF_BIND_NOW on AArch64 we don't reserve the GOT slot for a TLSDESC,
but we still emitted DT_TLSDESC_GOT and DT_TLSDESC_PLT. This caused random
memory corruption as the "special" value of (bfd_vma)-1 would be set for
dt_tlsdesc_got.
Since we don't have a value of dt_tlsdesc_got I also don't emit DT_TLSDESC_PLT
now becuase it would point to an incomplete PLT. To be able to write the PLT
entry DT_TLSDESC_GOT is needed and since we don't have one we can't write the
PLT entry either.
It is my understanding that GLIBC doesn't need these two entries when not lazy
loading. Conversely AArch32 does not reserve neither the GOT not the PLT slot
when doing DF_BIND_NOW.
AArch32 does not need these checks because these values are initialized to 0
and so the if (...) checks don't pass, but on AArch64 these are initialized
to (bfd_vma)-1 and thus we need some extra checks.

[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in
Armv8.5-A Memory Tagging Extension. This is part of the changes
that have been introduced recently in the 00bet10 release
All of these instructions have an updated register operand (Xt -> <Xt|SP>)
- STG <Xt|SP>, [<Xn|SP>, #<simm>]
- STG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STG <Xt|SP>, [<Xn|SP>], #<simm>
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]
- STZG <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZG <Xt|SP>, [<Xn|SP>], #<simm>
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]
- ST2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- ST2G <Xt|SP>, [<Xn|SP>], #<simm>
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]
- STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]!
- STZ2G <Xt|SP>, [<Xn|SP>], #<simm>
In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has
the same field as FLD_Rt but follows other semantics of Rn_SP.

Fix amd64->i386 linux syscall restart problem
This commit fixes some failures in gdb.base/interrupt.exp
when debugging a 32-bit i386 linux inferior from an amd64 host.
When running the following test...
make check RUNTESTFLAGS="--target_board unix/-m32 interrupt.exp"
... without this commit, I see the following output:
FAIL: gdb.base/interrupt.exp: continue (the program exited)
FAIL: gdb.base/interrupt.exp: echo data
FAIL: gdb.base/interrupt.exp: Send Control-C, second time
FAIL: gdb.base/interrupt.exp: signal SIGINT (the program is no longer running)
ERROR: Undefined command "".
ERROR: GDB process no longer exists
=== gdb Summary ===
When the test is run with this commit in place, we see 12 passes
instead. This is the desired behavior.
Analysis:
On Linux, when a syscall is interrupted by a signal, the syscall
may return -ERESTARTSYS when a signal occurs. Doing so indicates that
the syscall is restartable. Then, depending on settings associated
with the signal handler, and after the signal handler is called, the
kernel can then either return -EINTR or can cause the syscall to be
restarted. In this discussion, we are concerned with the latter
case.
On i386, the kernel returns this status via the EAX register.
When debugging a 32-bit (i386) process from a 64-bit (amd64)
GDB, the debugger fetches 64-bit registers even though the
process being debugged is 32-bit. Since we're debugging a 32-bit
target, only 32 bits are being saved in the register cache.
Now, ideally, GDB would save all 64-bits in the regcache and
then would be able to restore those same values when it comes
time to continue the target. I've looked into doing this, but
it's not easy and I don't see many benefits to doing so. One
benefit, however, would be that EAX would appear as a negative
value for doing syscall restarts.
At the moment, GDB is setting the high 32 bits of RAX (and other
registers too) to 0. So, when GDB restores EAX just prior to
a syscall restart, the high 32 bits of RAX are zeroed, thus making
it look like a positive value. For this particular purpose, we
need to sign extend EAX so that RAX will appear as a negative
value when EAX is set to -ERESTARTSYS. This in turn will cause
the signal handling code in the kernel to recognize -ERESTARTSYS
which will in turn cause the syscall to be restarted.
This commit is based on work by Jan Kratochvil from 2009:
https://sourceware.org/ml/gdb-patches/2009-11/msg00592.html
Jan's patch had the sign extension code in amd64-nat.c. Several
other native targets make use of this code, so it seemed better
to move the sign extension code to a linux specific file. I
also added similar code to gdbserver.
Another approach is to fix the problem in the kernel. Hui Zhu
tried to get a fix into the kernel back in 2014, but it was not
accepted. Discussion regarding this approach may be found here:
https://lore.kernel.org/patchwork/patch/457841/
Even if a fix were to be put into the kernel, we'd still need
some kind of fix in GDB in order to support older kernels.
Finally, I'll note that Fedora has been carrying a similar patch for
at least nine years. Other distributions, including RHEL and CentOS
have picked up this change and have been using it too.

Disable R_X86_64_PLT32 generation as branch marker on Solaris/x86
The fix H.J. implemented for PR gas/22791 in the thread starting at
[PATCH] x86-64: Treat PC32 relocation with branch as PLT32
https://sourceware.org/ml/binutils/2018-02/msg00065.html
is causing problems on Solaris/x86. The native linker is strongly
preferred there, and there's no intention of implementing the linker
optimization he plans there. Besides, the kernel runtime linker,
otherwise has no need to deal with that reloc at all, and instead of
adding (possibly even more) workarounds with no benefit, it seems
appropriate to disable the R_X86_64_PLT32 generation as branch marker on
Solaris/x86 in the first place.
The patch itself is trivial, the only complication is adapting the
testsuite. Since I've found no way to have conditional sections in the
.d files, I've instead used the solution already found elsewhere of
having separate .d files for the affected tests in an i386/solaris
subdirectory and skipping the original ones.
Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu without
regressions.

Use find_thread_in_random in select_event_lwp
I noticed that find_thread_in_random duplicates the code in

former.
There are two other spots in gdb that do this, but to unify all of

Another possible improvement is that find_thread_in_random could be

Use -qualified flag when setting temporary breakpoint in start command
When using the "start" command, GDB puts a temporary breakpoint on the
"main" symbol (we literally invoke the tbreak command). However, since
it does wild matching by default, it also puts a breakpoint on any C++
method or "main" function in a namespace. For example, when debugging
GDB, it creates a total of 24 locations:
(gdb) start
Temporary breakpoint 1 at 0x198c1e9: main. (24 locations)
as there are a bunch of methods called main in the selftests, such as
selftests::string_view::capacity_1::main()
If such method was called in the constructor of a global object, or a
function marked with the attribute "constructor", then we would stop at
the wrong place. Also, this causes a few extra symtabs (those that
contain the "wrong" mains) to be expanded for nothing.
The dummiest, most straightforward solution is to add -qualified when
invoking tbreak. With this patch, "start" creates a single-location
breakpoint, as expected.
I copied the start.exp test to start-cpp.exp and made it use a C++ test
file, which contains two main functions. The new test verifies that the
output of "start" is the output we get when we set a single-location
breakpoint.

Support buffer objects as handles in Inferior.thread_from_thread_handle()
InferiorThread.handle() returns a python bytes object. We'd like to
be able to pass the output of this function, a thread handle, to
Inferior.thread_from_thread_handle(). Up to now,
thread_from_thread_handle() expects to receive a gdb.Value input.
This commit adds support to also allow a python buffer object to be
passed as the handle.
infpy_thread_from_thread_handle() calls find_thread_by_handle() which
has the obvious functionality. It used to pass the thread handle via
a struct value pointer. I've revised this interface to instead pass a

Some gdb_exception{,error,quit} tweaks
- Explicitly include <string> for std::string.
- Use std::make_shared to construct gdb_exception::message instead of
operator new, avoiding one heap allocation (2 instead of 3). Add
'const char *fmt, va_list ap' parameters to
gdb_exception{,error,quit}'s ctors, and do the std::make_shared in
the gdb_exception ctor.
- gdb_exception_error's constructor does not need to have an 'enum
return_reason' parameter, since it is always RETURN_ERROR, by
definition.
- Similarly, gdb_exception_quit's contructor does not need to have
'enum return_reason'/'enum errors' parameters.
- In the gdb_exception_{quit,_error} ctors that take a gdb_exception
as argument, assert that they're being passed a gdb_exception object
of the right 'reason'.

Replace throw_exception with throw in some cases
This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

Make exceptions use std::string and be self-managing
This changes the exception's "message" member to be a shared_ptr
wrapping a std::string. This allows removing the stack of exception
messages, because now exceptions will self-destruct when needed. This
also adds a noexcept copy constructor and operator= to gdb_exception,
plus a "what" method.

Simplify exception handling
Now that cleanups have been removed, TRY/CATCH can't be SJLJ-based any
more. This patch simplifies the exception handling code, by removing
the non-working variants.
Note that the "pure" C++ exception handling code is removed as well; I
think the route forward must be to change exceptions to be
self-destructing, so that try_scope_depth can simply be removed.
Some longjmp-based code remains, as it is needed to throw an exception
through readline.

Make "all" depend on "info"
I've broken "make info" a couple of times now, because I sometimes
forget to run "make info" after modifying a Texinfo file.
I don't know why gdb's "make all" doesn't build the info pages. I
suspect this was some Cygnus-local oddity back in the day.
This patch changes doc/Makefile.in so that the info pages are built by
"make all". As a point of reference, Automake has essentially always
worked this way. According to the Automake manual (I didn't
double-check) this is required by the GNU coding standards.
The first time I sent this patch, I mentioned that I wanted to look
into some existing bugs in bugzilla about missing "makeinfo".
However, today I tried and I discovered that BFD requires makeinfo,
and builds its info file as part of "all". So, I think this change
doesn't worsen the situation for users in any way, and can simply go
in.

Revert the header-sorting patch
Andreas Schwab and John Baldwin pointed out some bugs in the header
sorting patch; and I noticed that the output was not correct when
limited to a subset of files (a bug in my script).
So, I'm reverting the patch. I may try again after fixing the issues
pointed out.

Use linux_get_auxv to get AT_PHDR in the PPC stub
This patch fixes a build error due to a call to ppc_get_auxv that was
left over after linux_get_hwcap and linux_get_hwcap2 were introduced
in:
974c89e0882ddb03e294eca76a9e3d3bef90eacf gdbserver: Add
linux_get_hwcap
Because the missing call fetched AT_PHDR and not AT_HWCAP,
linux_get_auxv is now visible.
This use also required ppc_get_auxv to return a status variable
indicating that the AT_PHDR entry was not found separately from the
actual value of of the auxv entry. Therefore, the new linux_get_auxv
function is changed to return a status variable and write the entry
value to a pointer passed as an argument.
Note that linux_get_hwcap and linux_get_hwcap2 still use the return
value as both an indicator of that the entry wasn't found and as the
actual value of the entry.
gdb/gdbserver/ChangeLog:
2019-04-05 Pedro Franco de Carvalho <pedromfc@linux.ibm.com>
* linux-low.c (linux_get_auxv): Remove static. Return auxv entry
value in argument pointer, return 1 if the entry is found and 0
otherwise. Move comment.
(linux_get_hwcap, linux_get_hwcap2): Use modified linux_get_auxv.
* linux-low.h (linux_get_auxv): Declare.
* linux-ppc-low.c (is_elfv2_inferior): Use linux_get_auxv.

Remove paren_depth global
This removes the "paren_depth" global. In most cases, it is made into
a static global in a given parser. I consider this a slight
improvement, because it makes it clear that the variable isn't used
for communication between different modules of gdb. The one exception
is the Rust parser, which already incorporates all local state into a
transient object; in this case the parser depth is now a member.

PowerPC bc extended branch mnemonics and "y" hints
This patch fixes a problem with disassembly of branch instructions
for processors complying with PowerPC ISA versions prior to version
2.0, ie. those that use "y" bit branch taken hints. Many of the
extended bcctr and bclr mnemonics that should have disassembled with a
"-" suffix, ie. not taken, did not display the "-" due to the ordering
in powerpc_opcodes. I believe it's been that way from the original
85dcf36d72b commit of ppc-opc.c.
I've also added a BH field (optional) to a few opcodes. This gives
better disassembly in raw mode, showing the branch taken hint in the
mnemonic as is done for bc. It would be reasonable to add a BH
field to all bcctr, bclr, and bctar extended mnemonics but that runs
into a small difficulty: Currently we print all or none of the
optional operands. That means for example that "bgectr cr2" would
display as "bgectr cr2,0" if a BH field is added to bgectr.
* ppc-opc.c (XLBH_MASK): Subtract off BH field from BB_MASK.
(powerpc_opcodes): Reorder bcctr and bclr extended mnemonics
to favour printing of "-" branch hint when using the "y" bit.
Allow BH field on bc{ctr,lr,tar}{,l}{-,+}.

gas: use literals/const16 for xtensa loop relaxation
Loop opcode relaxation that uses addi/addmi doesn't work well with other
relaxations that may cause code movement. Instead of encoding fixed loop
end offset in the relaxed sequence use l32r or a pair of const16 to load
loop end address. This way the address of the loop end gets a relocation
record and it gets updated appropriately.

RISC-V: Don't check ABI flags if no code section.
This fixes a glib build failure reported in PR 24389. Using ld -b binary
creates an object file with no elf header flags set which has the wrong ABI
info for riscv64-linux. But the file also has no code sections, so I added
code borrowed from the arm port that only checks the ELF header ABI flags if
there is a code section.

gdb/fortran: Handle internal function calls
If an convenience function is defined in python (or guile), then
currently this will not work in Fortran, instead the user is given
this message:
(gdb) set language fortran
(gdb) p $myfunc (3)
Cannot perform substring on this type
Compare this to C:
(gdb) set language c
(gdb) p $myfunc (3)
$1 = 1
After this patch we see the same behaviour in both C and Fortran.
I've extended the test to check that all languages can call the
convenience functions - only Fortran was broken.
When calling convenience functions in Fortran we don't need to perform
the same value preparation (passing by pointer) that we would for
calling a native function - passing the real value is fine.

gdb: Add $_cimag and $_creal internal functions
Add two new internal functions $_cimag and $_creal that extract the
imaginary and real parts of a complex value.
These internal functions can take a complex value of any type 'float
complex', 'double complex', or 'long double complex' and return a
suitable floating point value 'float', 'double', or 'long double'.
So we can now do this:
(gdb) p z1
$1 = 1.5 + 4.5 * I
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) p $_creal (z1)
$4 = 1.5
The components of a complex value are not strictly named types in
DWARF, as the complex type is itself the base type. However, once we
are able to extract the components it makes sense to be able to ask
what the type of these components is and get a sensible answer back,
rather than the error we would currently get. Currently GDB says:
(gdb) ptype z1
type = complex double
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) ptype $
type = <invalid type code 9>
With the changes in dwarf2read.c, GDB now says:
(gdb) ptype z1
type = complex double
(gdb) p $_cimag (z1)
$4 = 4.5
(gdb) ptype $
type = double
Which seems to make more sense.
