binutils: remove sparc64/mips64 workaround in objcopy build notes merge code
This patch removes a workaround recently installed in objcopy that
avoided removing duplicated notes in targets for which the number of
internal relocations may be bigger than the number of external
relocations. With the recent fixes in sparc64 and mips64, this
workaround is no longer necessary.
2017-05-19 Jose E. Marchesi <jose.marchesi@oracle.com>
* objcopy.c (merge_gnu_build_notes): Remove workaround that
prevented deleting relocations in duplicated notes in mips64 and
sparc.
commit 43cc5389bc4662b31cad02a9f13358bd367d0ab3

Use watchpoint's language when re-parsing expression
PR rust/21484 notes that watch -location does not work with Rust:
(gdb) watch -location a
syntax error in expression, near `) 0x00007fffffffe0f4'.
update_watchpoint tries to tell gdb that the new expression it creates
has C syntax:
/* The above expression is in C. */
b->language = language_c;
However, update_watchpoint doesn't actually use this language when
re-parsing the expression.
Originally I was going to fix this by saving and restoring the
language in update_watchpoint, but this regressed
gdb.dlang/watch-loc.exp, because the constructed expression actually
has D syntax (specifically the name is not parseable by C).
Next I looked at directly constructing an expression, and not relying
on the parser at all; but it seemed to me that upon a re-set, we'd
want to reparse the type, and there is no existing API to do this
correctly.
So, in the end I made a hook to let each language choose what
expression to use. I made all the languages other than Rust use the C
expression, because that is the status quo ante. However, this is
probably not truly correct. After this patch, at least, it is easy to
correct by someone who knows the language(s) in question.
Regtested by the buildbot.

MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count'
Revert parts of commit fee24f1c5bfe ("objdump improvements for mips
elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and
make the `->reloc_count' member of `struct bfd_section' hold the actual
number of internal relocations stored in its `->relocation' vector. To
do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count'
to the actual number of internal relocations retrieved and discard
`mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc'
and their corresponding target macros. Contrary to the description of
`mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes
generic relocation processing code happy and satisfies the "merge notes
section" binutils test case.
Add extra binutils test cases to expand the coverage of the generic
"merge notes section" test case, now passing with the n64 ABI, across
the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in
target configuration, and also to verify correctness of the relocations
produced. Conversely, do not provide any additional test cases for the
original issue addressed with the commit referred:
- objdump would display only 1/3 of the total number of relocations,
because it used the external relocation count, but each external
relocation is brought in as 3 internal relocations.
as n64 ABI relocation processing with `objdump -r' and `objdump -R' is
already widely covered across the GAS and LD test suites.

gdb: fix TYPE_CODE_ARRAY handling in sparc targets
gdb has a special type (TYPE_CODE_ARRAY) to support the gcc extension
(https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html).
TYPE_CODE_ARRAY is handled incorrectly for both (32- and 64-bit) modes
on Sparc machines.
Tested on sparc64-linux-gnu and sparc-solaris (32- and 64-bit mode).
6 tests ( from gdb/testsuite/gdb.base/gnu_vector.exp) failed on
sparc64-Linux and on sparc-Solaris in 32- and 64-bit mode. Now all
these tests passed. gdb/testsuite/gdb.base/gnu_vector.exp has 117
different cases for small (and not small) arrays and structures.
No regressions.

garbage collect debug sections when no alloc sections are kept
The pr20882 testcase fails on a number of targets that add attribute
or note sections to object files, and the default linker script says
those sections should be kept. This patch changes --gc-sections to
drop debug and special sections like .comment when no SEC_ALLOC
section in an object file is kept. The assumption is that debug
sections are describing code and data that will become part of the
final image in memory.
* elflink.c (_bfd_elf_gc_mark_extra_sections): Don't keep
debug and special sections when no non-note alloc sections in an

Fix test failure with Rust 1.18 and 1.19
With Rust 1.18 and 1.19, I saw some test suite failures. They were
all of the same form -- Box seems to be qualified in the output now,
like:
print box_some
$64 = core::option::Option<alloc::boxed::Box<u8>>::Some(0x7ffff6c21018 "\001\000")
... where the test was expecting Option<Box<u8>>.

Mark debug sections referenced by kept debug sections
If a debug section is referenced by a kept debug section, it should
also be kept.
Some targets, like mips, keep input files when there are some special
sections, like .gnu.attributes, even if input file is unused otherwise.
In this case, all debug sections are kept. The new test will fail on
such targets. We can either fix those targets or XFAIL the test.

Add alias command to cmd_list_element
When we add alias command, we call add_alias_cmd and pass the alias name
and command name. This implicitly requires the command and its prefix
commands are already added to cmdlist. This may not be true, for example,
add_com_alias ("tty", "set inferior-tty", class_alias, 0);
"inferior-tty" command is added to setlist, but setlist may not be added
to cmdlist (It depends on the order of related _initialize_XXX functions
called) so that we can't find "set inferior-tty" from cmdlist.
This patch fixes this problem by passing cmd_list_element of "inferior-tty"
to add_alias_cmd, so that cmd_list_element of "inferior-tty" doesn't have
to be reachable from cmdlist at that moment.

non_ir_ref_dynamic
dynamic_ref_after_ir_def is a little odd compared to other symbol
flags in that as the name suggests, it is set only for certain
references after a definition. It turns out that setting a flag for
any non-ir reference from a dynamic object can be used to solve the
problem for which this flag was invented, which I think is a cleaner.
This patch does that, and sets non_ir_ref only for regular object
references.
include/
* bfdlink.h (struct bfd_link_hash_entry): Update non_ir_ref
comment. Rename dynamic_ref_after_ir_def to non_ir_ref_dynamic.
ld/
* plugin.c (is_visible_from_outside): Use non_ir_ref_dynamic.
(plugin_notice): Set non_ir_ref for references from regular
objects, non_ir_ref_dynamic for references from dynamic objects.
bfd/
* elf64-ppc.c (add_symbol_adjust): Transfer non_ir_ref_dynamic.
* elflink.c (elf_link_add_object_symbols): Update to use
non_ir_ref_dynamic.
(elf_link_input_bfd): Test non_ir_ref_dynamic in addition to
non_ir_ref.
* linker.c (_bfd_generic_link_add_one_symbol): Likewise.

Merge remote-tracking branch 'gdb/master' into indexcxx
commit 88c1242dc0a1e1ab582a65ea8bd05eb5f244c59b
Author: Yao Qi <yao.qi@linaro.org>
Date: Wed May 24 17:23:52 2017 +0100
Move print_insn_XXX to an opcodes internal header
With the changes done in previous patches, print_insn_XXX functions
don't have to be external visible out of opcodes, because both gdb
and objdump select disassemblers through a single interface.
This patch moves these print_insn_XXX declarations from
include/dis-asm.h to opcodes/disassemble.h, which is a new header
added by this patch.

Use disassemble.c:disassembler select rs6000 disassembler
Nowadays, rs6000 disassembler is selected in different ways in
opcodes and gdb,
opcodes:
case bfd_arch_rs6000:
if (mach == bfd_mach_ppc_620)
disassemble = print_insn_big_powerpc;
else
disassemble = print_insn_rs6000;
break;
gdb:
if (arch == bfd_arch_rs6000)
set_gdbarch_print_insn (gdbarch, print_insn_rs6000);
else
set_gdbarch_print_insn (gdbarch, gdb_print_insn_powerpc);
I am not sure which one is the right one. However, such selection
should be done in one place instead of two.
gdb:
2017-05-24 Yao Qi <yao.qi@linaro.org>
* rs6000-tdep.c (gdb_print_insn_powerpc): Remove.
(rs6000_gdbarch_init): Don't call set_gdbarch_print_insn.

Use disassemble.c:disassembler select rl78 disassembler
This patch changes rl78 to let disassble.c:disassembler select
disassembler. rl78_get_disassembler doesn't handle the case
that abfd is NULL, so this patch also fix it.
gdb:
2017-05-24 Yao Qi <yao.qi@linaro.org>

is NULL, set cpu to E_FLAG_RL78_ANY_CPU.

Use disassemble.c:disassembler select h8300 disassembler
opcodes/disassble.c:disassembler select h8300 disassembler like this,
if (mach == bfd_mach_h8300h || mach == bfd_mach_h8300hn)
disassemble = print_insn_h8300h;
else if (mach == bfd_mach_h8300s
|| mach == bfd_mach_h8300sn
|| mach == bfd_mach_h8300sx
|| mach == bfd_mach_h8300sxn)
disassemble = print_insn_h8300s;
else
disassemble = print_insn_h8300;
which is the same as what gdb/h8300-tdpe.c does,
switch (info.bfd_arch_info->mach)
{
case bfd_mach_h8300:
...
set_gdbarch_print_insn (gdbarch, print_insn_h8300);
case bfd_mach_h8300h:
case bfd_mach_h8300hn:
...
set_gdbarch_print_insn (gdbarch, print_insn_h8300h);
case bfd_mach_h8300s:
case bfd_mach_h8300sn:
...
set_gdbarch_print_insn (gdbarch, print_insn_h8300s);
so we can leave disassble.c:disassembler doing the selection.
gdb:
2017-05-24 Yao Qi <yao.qi@linaro.org>
* h8300-tdep.c (h8300_gdbarch_init): Don't call
set_gdbarch_print_insn.

Delegate opcodes to select disassembler in GDB
This patch changes GDB to use disassembler selected by opcodes in
default, so that we don't have to duplicate the selection logic again
in GDB side. For example, gdb/score-tdep.c has
static int
score_print_insn (bfd_vma memaddr, struct disassemble_info *info)
{
if (info->endian == BFD_ENDIAN_BIG)
return print_insn_big_score (memaddr, info);
else
return print_insn_little_score (memaddr, info);
}
and opcodes/disassemble.c has the same logic,
case bfd_arch_score:
if (big)
disassemble = print_insn_big_score;
else
disassemble = print_insn_little_score;
This patch removes the logic in GDB and calls
opcodes/disassemble.c:disassembler in default to select disassembler.

Refactor disassembler selection
Nowadays, opcodes/disassemble.c:disassembler selects the proper
disassembler according to ABFD only. However, it actually
selects disassemblers according to arch, mach, endianess, and
abfd. This patch adds them to the parameters of disassembler,
so that its caller can still select disassemblers in case that
abfd is NULL (a typical case in GDB).
There isn't any functionality change.

* dis-asm.h (disassembler): Update declaration.

* disassemble.c (disassembler): Add arguments a, big and mach.
Use them.
sim/common:

commit d489d81d0934c4fda8c8aa68fbec1b1315cf8df0
Author: John Baldwin <jhb@FreeBSD.org>
Date: Tue Apr 18 10:49:44 2017 -0700
Cleanups to FreeBSD/mips native register operations.
Compare against the "raw" PC register number instead of the cooked
register number when determining if a register was handled by
PT_GETREGS. Previously the register fetch/store operations only tried
PT_GETREGS to fetch any individual register. The result was that
fetching or storing an individual register not covered by PT_GETREGS
(such as floating point registers) did not work.
While here, remove an early exit to simplify the code flow from the
PT_GETREGS / PT_SETREGS case, and add a getfpregs_supplies similar to
getregs_supplies to describe the registers supplied by PT_GETFPREGS
and PT_SETFPREGS.
gdb/ChangeLog:
* mips-fbsd-nat.c (getregs_supplies): Fix upper bound comparison.
(getpfpregs_supplies): New function.
(mips_fbsd_fetch_inferior_registers): Remove early exit and use
getfpregs_supplies.
(mips_fbsd_store_inferior_registers): Likewise.

gdb: Document vMustReplyEmpty remote packet
Add mention of the vMustReplyEmpty to the remote serial protocol
documentation. It is important that this packet be treated in the same
fashion as any other unknown 'v' packet, and I have tried to reflect
this in the description of the packet, it is not simply the case that we
_must_ return the empty string for this packet.
As the intention is that we should treat this packet as unknown then an
argument could be made that we should not document it, however, for
someone implementing a gdbserver from scratch, seeing an undocumented
packet arrive from gdb is confusing, and will probably cause them to
have to read the code in order to check how this packet should be
handled, which is not ideal.
gdb/doc/ChangeLog:
* gdb.texinfo (Packets): Document vMustReplyEmpty packet.

Print Rust unsized array types a bit more nicely
It's a bit difficult to create an unsized array type in Rust, but if
you do, right now ptype will show something like "[u8; ]". It really
should print "[u8]", though, which is what this patch implements.
This is part of PR 21466.
Built and regtested on x86-64 Fedora 25. I'm checking this in.

Rearrange gdb/configure.nat to make it simpler and less redundant
The previous commit introduced gdb/configure.nat, but it was just a
copy-and-past (with the necessary adjustments) from the files under
gdb/config/. We can do better than that.
Instead of using one big 'case' statement that matches the
${gdb_host_cpu} and then match each ${gdb_host}, it is possible to
remove a lof of redundancy by matching the most common ${gdb_host}'s
first, setting the common variables for each, and then proceed to
matching specific ${gdb_host}'s and ${gdb_host_cpu}'s. In other
words, reverse the order of the 'case's and take advantage of the fact
that a lot of parameters are the same for each host.
This commit was tested on x86_64 without regressions.

* configure.nat: Rearrange 'case' statements to match
host before cpu.
commit 21ea5acdd1bcfe89984b16b5bac730050c5cf05e
Author: Sergio Durigan Junior <sergiodj@redhat.com>
Date: Tue Apr 25 16:03:39 2017 -0400
Introduce "gdb/configure.nat" (and delete "gdb/config/*/*.mh" files)
Due to my ongoing work to make it possible for gdbserver to start the
inferior using the shell, I had to share the fork_inferior function
under the "nat/" directory. In order to do that, I created a new file
and put the function there; however, this meant that I now had to
update some of the *.mh files (under "gdb/config") and add the new
file as a dependency to be built natively. Bleh...
After talking a bit to Pedro about this, the idea came up to write a
new "gdb/configure.nat" file, a la "gdb/configure.tgt", which would
concentrate all of the native settings for each host/system. I
decided to tackle this issue.
The patch is simple. All of the previous Makefile variables that were
being declared inside the *.mh files are now inside "gdb/Makefile.in",
and "gdb/configure" is responsible for AC_SUBST'ing them. The
definitions of these variables were put inside "gdb/configure.nat", so
now they're shell variables. For excerpts of Makefile code, one must
create a file under "gdb/config/${gdb_cpu_host}" and reference it on
the "nat_extra_makefile_frag" variable.
It should now be easier to update the native dependencies of hosts in
this single file.
This has been tested on x86_64 without regressions.
gdb/ChangeLog:
2017-05-06 Sergio Durigan Junior <sergiodj@redhat.com>
* Makefile.in: Remove "@host_makefile_frag@". Add variables
NAT_FILE, NATDEPFILES, NAT_CDEPS, LOADLIBES, MH_CFLAGS, XM_CLIBS,
NAT_GENERATED_FILES, HAVE_NATIVE_GCORE_HOST. Add
"@nat_extra_makefile_frag@".
(Makefile): Remove dependency on "@frags@".

gdb: Disable -Werror for -Wmaybe-uninitialized
Newer GCCs are triggering false-positive -Wmaybe-uninitialized
warnings around code that uses gdb::optional:
https://sourceware.org/ml/gdb-patches/2017-05/msg00118.html
Using std::optional wouldn't help, it triggers the same warnings:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80635
Initializing the variables to quiet the warning would defeat the
purpose of gdb::optional. Making the optional ctor memset its storage
would be a pessimization. Wrapping gdb::optional's internals with
"#pragma GCC diagnostic push/ignored/pop" doesn't work, we'd have to
wrap uses of gdb::optional instead, which I think would get unwieldy
and ugly as we start using gdb::optional more and more.
The -Wmaybe-uninitialized warning is documented as producing false
positives (unlike -Wuninialized), so until we find a better
workaround, disable -Werror for this warning. You'll still see the
warning when building gdb, but it won't cause a build failure.
Tested by building with gcc 4.8.5, 5.3.1, and gcc trunk (20170428).

Fix get_core_register_section leak, introduce thread_section_name
This plugs a leak introduced in the previous change to
get_core_register_section, which removed an xfree call that is
actually necessary because the 'section_name' local is static.
From [1] it looks like the reason the variable was made static to
begin with, was just "laziness" to avoid having to think about freeing
it on every function return path:
https://sourceware.org/ml/gdb-patches/2005-03/msg00237.html
The easiest to fix that nowadays is to use a std::string.
I don't see a need to xstrdup the section name in the single-threaded
case though, and also there's more than one place that computes a
multi-threaded section name in the same way. So put the section name
computation in a wrapper class with state.

Fix PR21404 - assertion fail when calculating symbol size
Fix a host of problems related to adjustment of
symbol values and sizes when relaxing for avr.
1. Adjust symbol size first before adjusting symbol
value. Otherwise, a symbol whose value just got adjusted to the
relaxed address also ends up getting resized. See pr21404-1.s.
2. Reduce symbol sizes only if their span is below an
alignment boundary. Otherwise, the size gets decremented once when the
actual instruction is relaxed and padding bytes are added, and again
when the padding bytes are deleted (if padding ends up being unnecessary).
pr21404-2.s addresses that, and this bug is really the root cause of PR21404.
3. Adjust all symbol values before an alignment boundary.
Previous code did not adjust symbol values if they fell in the
would-be padded area, resulting in incorrect symbol values in some
cases (see pr21404-3.s).
4. Increase symbol sizes if alignment directives require so.
As pr21404-4.s shows
.global nonzero_sym
L1:
jmp L1
nonzero_sym:
nop
nop
.p2align 2
.size nonzero_sym, .-nonzero_sym
The two nops satisfy the 4 byte alignment at assembly time and
therefore the size of nonzero_sym is 4. Relaxation shortens
the 4 byte jmp to a 2 byte rjmp, and to satisfy 4 byte alignment
the code places 2 extra padding bytes after the nops, increasing
nonzero_sym's size by 2. This wasn't handled before.
If the assembly code does not have any align directives, then the
boundary is the section size, and symbol values and sizes == boundary
should also get adjusted. To handle that case, add a did_pad variable
and use that to determine whether it should use < boundary or <= boundary.
Also get rid of reloc_toaddr, which is now redundant. toaddr is now not
adjusted to handle the above case - the newly added
did_pad variable does the job.
pr21404-{5,6,7,8} are the same testcases written for local symbols, as
the code handles them slightly differently.

MIPS16/GAS: Relax 32-bit non-PIC PC-relative synthetic instructions
Implement the relaxation of MIPS16 PC-relative synthetic LA, DLA, LW and
LD instructions to an equivalent sequence of instructions produced where
the address operand requested is out of range, absolute or requires
linker relocation, for ABIs that use 32-bit addressing and non-PIC code.
The sequence generated uses the register specified for the destination
operand as a temporary and begins with LI to load the high 16-bit part
of the address, then continues with SLL by 16 bits to move that part
into place and finally completes with a suitable operation corresponding
to the synthetic instruction used, one of: 2-argument ADDIU, 2-argument
DADDIU, absolute LW, and absolute LD respectively, providing the low
16-bit part of the address. All instructions use the extended encoding.
As a special exception accept absolute addresses for relaxation even in
PIC code.
For example:
la $2, 0x12345678
produces code as:
li $2, 0x1234
sll $2, $2, 16
addiu $2, 0x5678
would.
Where linker relocation is required emit an R_MIPS16_HI16 relocation on
the initial LI instruction and an R_MIPS16_LO16 relocation on the final
operation.
For example (where `foo' is not local):
lw $3, foo
produces code as:
li $3, %hi(foo)
sll $3, $3, 16
lw $3, %lo(foo)($3)
would.
Emit assembly warnings as appropriate where this new relaxation triggers
in the `nomacro' mode or for an instruction manually placed in a branch
delay slot in the `noreorder' mode. Refrain from relaxation where an
explicit instruction size suffix has been used and in the `noautoextend'
mode.

Make sure malloc is linked into gdb.cp/oranking.cc.
On some platforms, e.g., arm-eabi-none, we need to make certain that
malloc is linked into the program because the test suite uses function
calls requiring malloc:
(gdb) p foo101("abc")
evaluation of this expression requires the program to have a function "malloc".

MIPS16/GAS: Fix absolute references with PC-relative synthetic instructions
Complement commit 88a7ef168927 ("MIPS16/GAS: Restore unsupported
relocation diagnostics") and also propagate constant expressions, either
already reduced from absolute symbol references or created from literals
in the first place, used as a PC-relative operand with the MIPS16 LA,
LW, DLA and LD synthetic instructions to relaxation, matching the way
forward absolute symbol references have been handled as from the commit
referred and letting relaxation produce any necessary relocations, if
possible, for the absolute value requested to be reproduced at the run
time.
Call `symbol_append' for any expression symbol created for the purpose
of MIPS16 relaxation as with constant expressions now propagated from
earlier on such symbols may make it through and have R_MIPS16_PC16_S1
relocations emitted against, and therefore need to appear in the symbol
table produced.

RISC-V: Change CALL macro to use ra as the temporary address register
e.g.
1: auipc ra, %pcrel_hi(symbol)
jalr ra, %pcrel_lo(1b)(ra)
The use of ra instead of t1 for address construction provides an
opportunity for a microarchitecture to elide the write of the
destination address, and instead read the target address as an
immediate spread across the fused auipc+jalr pair. The link
register ra in the jalr overwrites the target address temporary.

Change field separator in gdbarch.sh
The fields in the description of the gdbarch interface are separated
using colons. That becomes a problem if we want to use things like
std::vector in it. This patch changes the field separator to use
semicolons instead.
I think there's very little chance we'll ever want to use a semicolon in
one of the fields, but if you think another character would be more
appropriate, let me know.

Make environ.exp run on all platforms (and create info-program.exp)
This has been on my TODO list for a while. There's a really old bug
about this (PR testsuite/8595), and there was no reason for
environ.exp to be specific for hppa* targets. So this patch removes
this constraint, modernizes the testcase, and cleans up some things.
Most of the tests remained, and some were rewritten (especially the
one that checks if "show environment" works, which is something kind
of hard to do).
As a bonus, I'm adding a separated info-program.exp file containing
all the tests related to "info program" that were present on
environ.exp.
Tested locally, everything still passes.

Make various lm_info implementations inherit from a base class
The lm_info structure is used to store target specific information about
mapped libraries. It is currently defined as an opaque type in solist.h
and a pointer to it is included in solist, the target-agnostic object
representing a loaded shared library. Multiple targets define their own
implementation of lm_info.
In anticipation of using C++ stuff (e.g. vector) in the lm_info objects,
we first need to avoid different definitions of classes with the same
name (which violates the one definition rule). This patch does it by
having a base class (lm_info_base) from which all the specific lm_info
derive. Each implementation is renamed to something that makes sense
(e.g. lm_info_aix for AIX). The next logical step would probably be to
derive directly from so_list, it's not really obvious, so I'll keep that
for another day.
One special case is the Neutrino (nto) support. It uses SVR4-style
libraries, but overrides some methods. To do that, it needed to have
its own copy of SVR4's lm_info structure in nto-tdep.c, because it was
just not possible to put it in solib-svr4.h and include that file. Over
time, that copy got out of sync, which is still the case today. I can
only assume that the lm_addr function in nto-tdep.c is broken right now.
The first field of the old lm_info was a pointer (gdb_byte *), whereas
in the new lm_info it's an address in the inferior (CORE_ADDR). Trying
to use that field today probably results in a crash. With this
refactor, it's now possible to put lm_info_svr4 in solib-svr4.h and just
include it. I have adapted the code in nto-tdep.c to that it builds,
but it's probably not correct. Since I don't have the knowledge nor
setup to try this on Neutrino, somebody else would have to fix it. But
I am confident that I am not making things worse than they already are.

Standardize darwin's lm_info
Darwin's lm_info structure is used a little bit differently than the
other solib implementations. The other implementations first allocate
an so_list object, then instanciate their specific lm_info structure,
and assign it to so_list::lm_info.
The Darwin implementation allocates both at the same time
(darwin_so_list). This patch changes it to be like the others, so that
we'll be able to do some generalizations later.
gdb/ChangeLog:
* solib-darwin.c (struct darwin_so_list): Remove.
(darwin_current_sos): Allocate an so_list object instead of a
darwin_so_list, separately allocate an lm_info object.
(darwin_free_so): Free lm_info.

Fix overload resolution involving rvalue references and cv qualifiers.
The following patch fixes several outstanding overload resolution problems
with rvalue references and cv qualifiers in the test suite. The tests for
these problems typically passed with one compiler version and failed with
another. This behavior occurs because of the ordering of the overloaded
functions in the debug info. So the first best match "won out" over the
a subsequent better match.
One of the bugs addressed by this patch is the failure of rank_one_type to
account for type equality of two overloads based on CV qualifiers. This was
leading directly to problems evaluating rvalue reference overload quality,
but it is also highlighted in gdb.cp/oranking.exp, where two test KFAIL as
a result of this shortcoming.
I found the overload resolution code committed with the rvalue reference
patch (f9aeb8d49) needlessly over-complicated, and I have greatly simplified
it. This fixes some KFAILing tests in gdb.exp/rvalue-ref-overload.exp.
gdb/ChangeLog
* gdbtypes.c (LVALUE_REFERENCE_TO_RVALUE_BINDING_BADNESS)

Add missing incref when creating Inferior Python object
The test py-inferior.exp fails when using a debug build of Python 3.6. I don't
see it failing with my system's default Python, but it might be related to the
different memory allocation scheme used when doing a build with pydebug.
The issue is that we are missing a Py_INCREF in
inferior_to_inferior_object. The PyObject_New function initializes the
object with a refcount of 1. If we assume that this refcount
corresponds to the reference we are returning, then we are missing an
incref for the reference in the inferior data.
The counterpart for the incref that corresponds to the reference in the
inferior data is in py_free_inferior, in the form the gdbpy_ref instance.
Here's how I can get it to crash (with some debug output):
$ ./gdb -nx -ex "set debug python 1"
(gdb) add-inferior
Added inferior 2
(gdb) python infs = gdb.inferiors()
Creating Python Inferior object inf = 1
Creating Python Inferior object inf = 2
(gdb) remove-inferiors 2
py_free_inferior inf = 2
infpy_dealloc inf = <unknown>
(gdb) python infs = None
Fatal Python error: Objects/tupleobject.c:243 object at 0x7f9cf1a568d8 has negative ref count -1
Current thread 0x00007f9cf1b68780 (most recent call first):
File "<string>", line 1 in <module>
[1] 408 abort (core dumped) ./gdb -nx -ex "set debug python 1"
After having created the inferiors object, their refcount is 1 (which
comes from PyObject_New), but it should be two. The gdb inferior object
has a reference and the "infs" list has a reference.
When invoking remove-inferiors, py_free_inferior gets called. It does
the decref that corresponds to the reference that the gdb inferior
object kept. At this moment, the refcount drops to 0 and the object
gets deallocated, even though the "infs" list still has a reference.
When we set "infs" to None, Python tries to decref the already zero
refcount and the assert triggers.
With this patch, it looks better:
(gdb) add-inferior
Added inferior 2
(gdb) python infs = gdb.inferiors()
Creating Python Inferior object inf = 1
Creating Python Inferior object inf = 2
(gdb) remove-inferiors 2
py_free_inferior inf = 2
(gdb) python infs = None
infpy_dealloc inf = <unknown>
gdb/ChangeLog:
* python/py-inferior.c (inferior_to_inferior_object): Increment reference
count when creating the object.

MIPS/GAS: Fix `.option picX' handling with relaxation
Correct the handling of `.option pic0' and `.option pic2' GAS pseudo-ops
in relaxation and use the setting of `mips_pic' (which these directives
control) as at the time a relaxed frag has been created rather than the
final `mips_pic' setting at the end of the source file processed.
To do so record whether `mips_pic' is NO_PIC or not in the frag itself
and use this information throughout relaxation instead of `mips_pic' to
decide which of NO_PIC or SVR4_PIC to produce machine code for, fixing
code generation and removing a possible fatal failure reproducible with:
$ as -32 --relax-branch -o option-pic-relax-3.o option-pic-relax-3.s
option-pic-relax-3.s: Assembler messages:
option-pic-relax-3.s:7: Warning: relaxed out-of-range branch into a jump
option-pic-relax-3.s: Internal error in cvt_frag_to_fill at .../gas/write.c:490.
Please report this bug.
$
using the test source included, due to a buffer overrun in filling the
variable part of a frag.
Likewise use the `fx_tcbit2' flag of a BFD_RELOC_16_PCREL_S2 fixup to
handle the simple case of substituting an out of range unconditional
branch with an equivalent absolute jump in NO_PIC code.
Retain the current way of VXWORKS_PIC use, which commit 41a1578ed17c

`.option picX' with.

[gdbarch] New method "execute_dwarf_cfa_vendor_op" and migrate SPARC to it
Recently a feature called "return address signing" has been added to GCC to
prevent stack smash stack on AArch64. For details please refer:
https://gcc.gnu.org/ml/gcc-patches/2017-01/msg00376.html
GDB needs to be aware of this feature so it can restore the original return
address which is critical for unwinding.
On compiler side, whenever return address, i.e. LR register, is mangled or
restored by hardware instruction, compiler is expected to generate a
DW_CFA_AARCH64_negate_ra_state to toggle return address signing status.
DW_CFA_AARCH64_negate_ra_state is using the same CFI number and
therefore need to be multiplexed with DW_CFA_GNU_window_save which was designed
for SPARC.
A new gdbarch method "execute_dwarf_cfa_vendor_op" is introduced by this patch.
It's parameters has been restricted to those only needed by SPARC and AArch64
for multiplexing DW_CFA_GNU_window_save which is a CFI operation takes none
operand. Should any further DWARF CFI operation want to be multiplexed in the
future, the parameter list can be extended. Below is the current function
prototype.
typedef int (gdbarch_execute_dwarf_cfa_vendor_op_ftype)
(struct gdbarch *gdbarch, gdb_byte op, struct dwarf2_frame_state *fs);
DW_CFA_GNU_window_save support for SPARC is migrated to this new gdbarch
method by this patch.

MIPS/readelf: With `-A' also dump GOT in static binaries
A static, non-relocated global offset table will be embedded in static
binaries produced from objects containing any kind of GOT relocations,
generally PIC code. All symbols will have been resolved in static link
in such binaries making all GOT entries local and their values final as
there is no run-time load processing further performed.
Dump such GOT with `readelf -A' like already done with regular GOT, to
make it easier to examine static code that uses accesses via the GOT
pointer. There will be no dynamic segment or section in a static binary
to get the GOT pointer (DT_PLTGOT) from, so use section headers to find
a `.got' section instead.

gas: sparc: fix relaxation of CALL instruction into branches in a.out targets
This patch avoids CALL instructions to be optimized into branches if
the symbols referred to in the CALL instruction are not fully resolved
at the time the assembler writes its output.
Tested in sparc64-linux-gnu and sparc-sun-sunos4.1.3 targets.
No regressions.

memset, at compile time.

Don't memset non-POD types: struct btrace_insn
struct btrace_insn is not a POD [1] so we shouldn't be using memset to
initialize it [2].
Use list-initialization instead, wrapped in a "pt insn to btrace insn"
function, which looks like just begging to be added next to the
existing pt_reclassify_insn/pt_btrace_insn_flags functions.

So, VECs (given it's C roots) rely on memcpy/memcpy of VEC elements to
be well defined, in order to grow/reallocate its internal elements
array. This means that we can only put trivially copyable types in
VECs. E.g., if a type requires using a custom copy/move ctor to
relocate, then we can't put it in a VEC (so we use std::vector
instead). But, as shown above, we're violating that requirement.
btrace_insn is currently not trivially copyable, because it contains
an enum_flags field, and that is itself not trivially copyable. This
patch corrects that, by simply removing the user-provided copy
constructor and assignment operator. The compiler-generated versions
work just fine.
Note that std::vector relies on std::is_trivially_copyable too to know
whether it can reallocate its elements with memcpy/memmove instead of
having to call copy/move ctors and dtors, so if we have types in
std::vectors that weren't trivially copyable because of enum_flags,
this will make such vectors more efficient.

[GAS/ARM] Fix expansion of ldr pseudo instruction
The LDR rX, =cst pseudo-instruction suffers from two issues for loading
integer constants in Thumb mode:
- movs is used if the constant and register can be encoded using that
instruction which leads to unexpected behavior due to its flag-setting
behavior
- mov.w, movw and mvn are used for r13 (sp) and r15 (pc) but these
encoding are marked as UNPREDICTABLE
This patch fixes those issues and update testing accordingly.

Author: Tom Tromey <tom@tromey.com>
Date: Wed Apr 12 16:15:14 2017 -0600
Use ui_out_emit_tuple in tracepoint.c
This changes some code in tracepoint.c to use ui_out_emit_tuple. One
of these involved removing an otherwise unrelated cleanup (changing
type to std::string) and the other involved introducing a new block.

* tracepoint.c (tvariables_info_1)
(print_one_static_tracepoint_marker): Use ui_out_emit_tuple.
commit 46b9c12945629fffb61001a8f13a37c96675c0b7
Author: Tom Tromey <tom@tromey.com>
Date: Wed Apr 12 16:10:02 2017 -0600
More uses of ui_out_emit_tuple
This patch adds a few more uses of ui_out_emit_tuple. In these cases
a slightly more complicated change was needed. This also adds
annotate_arg_emitter, for use in stack.c, to avoid having to introduce
a new scope and reindent the code for a single call.
ChangeLog
2017-04-22 Tom Tromey <tom@tromey.com>
* stack.c (print_frame_arg): Use ui_out_emit_tuple,
annotate_arg_emitter.
* breakpoint.c (print_mention_watchpoint)
(print_mention_masked_watchpoint): Use ui_out_emit_tuple.
* annotate.h (struct annotate_arg_emitter): New.
commit 2e78302469502f4f8a98144b60c09d4d9b6438fd
Author: Tom Tromey <tom@tromey.com>
Date: Wed Apr 12 08:23:08 2017 -0600
Use ui_out_emit_tuple
This patch changes various places to use ui_out_emit_tuple,
eliminating a number of cleanups. This patch only tackles "easy"
cases, which are ones where the cleanups in question were
block-structured and did not involve any changes other than the
obvious replacement.

doc: Improve documentation about MI thread output
I noticed that the documentation on how the info about threads is output
in MI is duplicated and not up to date. The duplication is between the
"GDB/MI Thread Information" page and the -thread-info result
description.
I improved the "GDB/MI Thread Information" page a bit and referred to it
in the -thread-info doc. This way, the -thread-info doc is more precise
(it did not mention the "threads" and "current-thread-id" attributes)
and concise.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Information): Add missing
fields, re-word some things.
(GDB/MI Thread Commands): Describe fields found in the output of
-thread-info, remove description of fields in the
thread output tuple, replace with a cross-reference to "GDB/MI
Thread Information".

Remove dead code and "current" field from MI thread output doc
The MI documentation says that -thread-info output contains a "current"
field in the current thread tuple, with the value "*". Current GDB
master does not do this, and I couldn't find any GDB version that did.
I suspect that it was never the case.
The code that would correspond to this in print_thread_info_1 is
essentially dead code. The calls to uiout->text end up in
mi_out::do_text, which is empty.
This patch removes the documentation bit and the dead code. This
"current" field is not necessary, since -thread-info outputs a
"current-thread-id" field.
gdb/ChangeLog:
* thread.c (print_thread_info_1): Remove dead code.
gdb/doc/ChangeLog:
* gdb.texinfo (GDB/MI Thread Commands): Remove "current" field
from -thread-info output.

i386: Avoid dynamic symbol with GOT reference in PIE
GOT reference to global symbol in PIE will lead to dynamic symbol. It
becomes a problem when "time" or "times" is defined as a variable in
an executable, clashing with functions of the same name in libc. If
a symbol isn't undefined weak symbol, don't make it dynamic in PIE and
generate R_386_RELATIVE relocation.

Simplify regcache_restore
This patches removes the 2nd argument of regcache_restore, because it
is only called by regcache_cpy. In regcache_cpy, if regcache_restore
is called, dst is not readonly, but src is readonly. So this patch
adds an assert that src is readonly in regcache_restore.
regcache_cook_read read everything from a readonly regcache cache
(src)'s register_buffer, and register status is from ->register_status.

argument 3 with regcache. Get register status from

Skip PIE indirect5 and indirect6 tests on i386
On i386, since GOT reference is needed to access global symbols in PIE,
those symbols are made dynamic. Crash happens when there is a reference
to the same global symbol with a different symbol type in a shared
object. Since mixing different types of the same symbol doesn't work in
general, this patch skips those tests on i386 as well as compiles non-PIE
indirect5 and indirect6 tests with $NOPIE_LDFLAGS and $NOPIE_CFLAGS.

ELF/LD: Always consider STB_LOCAL symbols local
Do not require forced local (STB_LOCAL) symbols to have a definition in
a regular file to be considered to resolve local to the current module,
matching `elf_link_renumber_local_hash_table_dynsyms'. In the absence
of a regular definition any reference to a STB_LOCAL symbol will have to
be garbage collected along with the undefined symbol itself, or the link
will eventually fail. Either way the symbol concerned is not going to
be external.

Handle symbol defined in IR and referenced in DSO
We need to make an IR symbol visible if it is defined in an IR object
and referenced in a dynamic object. When --as-needed is used, since
linker removes the IR symbol reference of the dynamic object if the
dynamic object isn't needed in the first pass, the IR definition isn't
visible to the dynamic object even if the dynamic object becomes needed
in the second pass. Add dynamic_ref_after_ir_def to bfd_link_hash_entry
to track IR symbol which is defined in an IR object and later referenced
in a dynamic object. dynamic_ref_after_ir_def is preserved when restoring
the symbol table for unneeded dynamic object.

Fix removing inferiors from within "thread apply" commands
This patch fixes an internal error exposed by a test that does
something like:
define kill-and-remove
kill inferiors 2
remove-inferiors 2
end
# Start one inferior.
start
# Start another inferior.
add-inferior 2
inferior 2
start
# Kill and remove inferior 1 while inferior 2 is selected.
thread apply 1.1 kill-and-remove
The internal error looks like this:
Thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677)):
[Switching to inferior 1 [process 20677] (gdb/testsuite/outputs/gdb.threads/threadapply/threadapply)]
[Switching to thread 1.1 (Thread 0x7ffff7fc2700 (LWP 20677))]
#0 main () at src/gdb/testsuite/gdb.threads/threadapply.c:38
38 for (i = 0; i < NUM; i++)
src/gdb/inferior.c:66: internal-error: void set_current_inferior(inferior*): Assertion `inf != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/threadapply.exp: kill_and_remove_inferior: try kill-and-remove: thread apply 1.1 kill-and-remove (GDB internal error)
There are several problems around this area of the code. One is that
in do_restore_current_thread_cleanup, we do a look up of inferior by
ptid, which can find the wrong inferior if the previously selected
inferior exited and some other inferior was started with a reused pid
(rare, but still...).
The other problem is that the "remove-inferiors" command rejects
attempts to remove the current inferior, but when we get to
"remove-inferiors" in a "thread apply THR remove-inferiors 2" command,
the current inferior is the inferior of thread THR, not the previously
selected inferior, so if the previously selected inferior was inferior
2, that command still manages to wipe it, and then gdb restores the
old selected inferior, which is now a dangling pointer...
So the fix here is:
- Make make_cleanup_restore_current_thread store a pointer to the
previously selected inferior directly, and use it directly instead
of doing ptid look ups.
- Add a refcount to inferiors, very similar to thread_info's refcount,
that is incremented/decremented by
make_cleanup_restore_current_thread, and checked before deleting an
inferior. To avoid duplication, a new refcounted_object type is
added, that both thread_info and inferior inherit from.

Make inferior::detaching a bool, and introduce scoped_restore::release()
I left making inferior::detaching a bool to a separate patch, because
doing that makes a make_cleanup_restore_integer call in
infrun.c:prepare_for_detach no longer compile (passing a 'bool *' when
an 'int *' is expected). Since we want to get rid of cleanups anyway,
I looked at converting that to a scoped_restore. However,
prepare_for_detach wants to discard the cleanup on success, and
scoped_restore doesn't have an equivalent for that. So I added one --
I called it "release()" because it seems like a natural fit in the way
standard components call similarly-spirited methods, and, it's also
what the proposal for a generic scope guard calls it too, AFAICS:
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n4189.pdf
I've added some scoped_guard unit tests, while at it.

gdb_xml_parser: make data fields private and make more functions methods
This patch makes the data fields of gdb_xml_parser private, and makes
more functions be gdb_xml_parser methods. This is mostly for better
encapsulation.
Some free functions have their parsing-related guts converted to
methods, while the free functions remain, as they're used as expat
callbacks. Now their only job is to be small shims that restore back
the gdb_xml_parser type, defer work to the corresponding method, and
make sure C++ exceptions don't cross expat.
More C++-fycation of the XML parsers built on top of gdb_xml_parser
could follow, but this was my stopping point.

gdb::optional unit tests
I thought I'd add some unit tests to make sure gdb::optional behaved
correctly, and started writing some, but then thought/realized that
libstdc++ already has extensive testing for C++17 std::optional, which
gdb::optional is a subset of, and thought why bother writing something
from scratch. So I tried copying over a subset of libstdc++'s tests
(that ones that cover the subset supported by gdb::optional), and was
positively surprised that they mostly work OOTB. This did help shake
out a few bugs from what I was implementing in the previous patch to
gdb::optional. Still, it's a good chunk of code being copied over, so
if people dislike this copying/duplication, I can drop this patch.

More gdb::optional features
Currently we can't use gdb::optional<T> as function return type,
because gdb::optional's copy ctor is deleted. For example, with:
gdb::optional<int> function ()
{
gdb::optional<int> opt;
....
return opt;
we get:
src/gdb/foo.c: In function ‘gdb::optional<int> foo()’:
src/gdb/foo.c:75:10: error: use of deleted function ‘gdb::optional<T>::optional(const gdb::optional<T>&) [with T = int]’
return opt;
^
In file included from src/gdb/foo.c:68:0:
src/gdb/common/gdb_optional.h:53:3: note: declared here
optional (const optional &other) = delete;
^
I started by fixing that, and then ran into another missing feature,
also fixed by this patch.
The next feature I'm missing most from gdb::optional<T> compared to
std::optional<T> is construction/move/assignment from a T, instead of
having to default construct an gdb::optional and then use
optional::emplace(....).
For example:
gdb::optional<std::string> function ()
{
gdb::optional<std::string> opt;
std::string str;
...
opt.emplace (std::move (str));
return opt;
vs
gdb::optional<std::string> function ()
{
std::string str;
...
return str;
The copy/move ctor/assign methods weren't initialy implemented because
std::optional supports construction from a type U if U is convertible
to T too, and has rules to decide whether the ctors are
explicit/implicit based on that, and rules for whether the ctor should
be trivial or not, etc., which leads to a much more complicated
implementation.
If we stick to supporting copy/move construction/assignment of/to an
optional<T> from exactly only optional<T> and T, then all that
conversion-related complication disappears, and we still gain
convenience in most use cases.
The patch also makes emplace return a reference to the constructor
object, per C++17 std::optional, and adds a reset method, againt
because std::optional has one and it's trivial to support it. These
two changes are a requirement of the gdb::optional unit testing patch

commit 010151c9146eb2a299686e41c714e57c344be8e8
Author: Pedro Alves <palves@redhat.com>

C++-ify gdb/xml-support.c a bit to eliminate cleanups
Basically convert cleanups to destructors in gdb_xml_parser and
xinclude_parsing_data, and then allocate objects of those types on the
stack.
More C++-ification is possible / will follow, but this removes a few
make_cleanup calls already.
gdb/ChangeLog:
2017-04-18 Pedro Alves <palves@redhat.com>
* xml-support.c (gdb_xml_parser): Add ctor/dtor. Make is_xinclude
a bool.
(gdb_xml_end_element): Change type of first parameter.
(gdb_xml_cleanup): Rename to ...
(gdb_xml_parser::~gdb_xml_parser): ... this.
(gdb_xml_create_parser_and_cleanup): Delete with ...
(gdb_xml_parser::gdb_xml_parser): ... creation parts factored out
to this new ctor.
(gdb_xml_parse_quick): Create a local gdb_xml_parser instead of
using gdb_xml_create_parser_and_cleanup.
(xinclude_parsing_data): Add ctor/dtor.
(xml_xinclude_cleanup): Delete.
(xml_process_xincludes): Create a local xinclude_parsing_data
instead of heap-allocating one. Create a local gdb_xml_parser
instead of heap-allocating one with
gdb_xml_create_parser_and_cleanup.

Undo dynamic symbol state after regular object sym type mismatch
We already handle the case of an object file first defining a symbol
that a later shared library also defines where the symbol types are
incompatible. This patch handles the reverse, when a later object
file defines an incompatible symbol defined by an earlier shared
library.

incompatible type to that defined by an earlier shared lib.

Initialize gdb::optional empty payload to quiet false -Wmaybe-uninitialized warnings
Commit ecfb656c37b982 ("dwarf2read.c: Make dir_index and
file_name_index strong typedefs") added a use of gdb::optional that
triggers bogus -Wmaybe-uninitialized warnings:
GCC trunk is complaining like this:
../../binutils-gdb/gdb/dwarf2read.c: In function void read_formatted_entries(bfd*, const gdb_byte**, line_header*, const comp_unit_head*, void (*)(line_header*, const char*, dir_index, unsigned int, unsigned int)):
../../binutils-gdb/gdb/dwarf2read.c:17779:65: error: fe.file_entry::length may be used uninitialized in this function [-Werror=maybe-uninitialized]
callback (lh, fe.name, fe.d_index, fe.mod_time, fe.length);
^
../../binutils-gdb/gdb/dwarf2read.c:17779:65: error: *((void*)& fe +8) may be used uninitialized in this function [-Werror=maybe-uninitialized]
../../binutils-gdb/gdb/dwarf2read.c:17779:65: error: fe.file_entry::mod_time may be used uninitialized in this function [-Werror=maybe-uninitialized]
../../binutils-gdb/gdb/dwarf2read.c:17779:65: error: fe.file_entry::name may be used uninitialized in this function [-Werror=maybe-uninitialized]
While some older GCCs are complaining like this:
../../binutils-gdb/gdb/dwarf2read.c: In function void read_formatted_entries(bfd*, const gdb_byte**, line_header*, const comp_unit_head*, void (*)(line_header*, const char*, dir_index, unsigned int, unsigned int)):
../../binutils-gdb/gdb/dwarf2read.c:17779:65: error: uint may be used uninitialized in this function [-Werror=maybe-uninitialized]
callback (lh, fe.name, fe.d_index, fe.mod_time, fe.length);
Looking around the web, I see that boost's optional implementation
triggers this kind of issue often too. See:
http://www.boost.org/doc/libs/1_63_0/libs/optional/doc/html/boost_optional/tutorial/gotchas/false_positive_with__wmaybe_uninitialized.html
I noticed that replacing the gdb::optional uses with real C++17
std::optional uses against GCC 7/trunk makes the warnings go away.
Looking at the implementation, AFAICS, libstdc++ always initializes
its "empty" union payload member (_M_empty, which is defined as an
empty class, like ours). I.e., all payload types have this ctor:
struct _Optional_payload.....
{
constexpr _Optional_payload()
: _M_empty() {}
The constexpr makes a diference too. Without it, GCC7 still warns.
So I'm applying the same treatment to our gdb::optional.
gdb/ChangeLog:
2017-04-05 Pedro Alves <palves@redhat.com>
* common/gdb_optional.h (optional::optional): Make constexpr and
initialize m_dummy.

PR ld/21233: Avoid sweeping forced-undefined symbols in section GC
Complement commit 902e9fc76a0e ("PR ld/20828: Move symbol version
processing ahead of GC symbol sweep"), commit b531344c34b0 ("PR
ld/20828: Reorder the symbol sweep stage of section GC") and commit
81ff47b3a546 ("PR ld/20828: Fix linker script symbols wrongly forced
local with section GC"), and prevent symbols forcibly entered in the
output file with the use of the `--undefined=' or `--require-defined='
linker command line options or the EXTERN linker script command from
being swept in section garbage collection and consequently recorded in
the dynamic symbol table as local entries. This happens in certain
circumstances, where a symbol reference also exists in one of the static
input files, however only in a section which is garbage-collected and
does not make it to the output file, and the symbol is defined in a
dynamic object present in the link.
For example with the `i386-linux' target and the `pr21233.s' and
`pr21233-l.s' sources, and the `pr21233.ld' linker script included with
this change we get:
$ as -o pr21233-l.o pr21233-l.s
$ ld -shared -T pr21233.ld -o libpr21233.so pr21233-l.o
$ as -o pr21233.o pr21233.s
$ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so
$ readelf --dyn-syms pr21233
Symbol table '.dynsym' contains 2 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 00000000 0 OBJECT LOCAL DEFAULT UND bar
$
which makes the run-time `bar' dependency of the `pr21233' executable
different from its corresponding link-time dependency, i.e. the presence
of `libpr21233.so' and its `bar' symbol is required at the link time,
however at the run time a copy of `libpr21233.so' without `bar' will do.
Similarly with `--undefined=' and EXTERN which do not actually require
the reference to the symbol requested to be satisfied with a definition
at the link time, however once the definition has been pulled at the
link time, so it should at the dynamic load time.
Additionally with the `mips-linux' target we get:
$ ld --gc-sections -e foo --require-defined=bar -T pr21233.ld -o pr21233 pr21233.o libpr21233.so
ld: BFD (GNU Binutils) 2.28.51.20170324 assertion fail .../bfd/elfxx-mips.c:3861
$
as the target is not prepared to handle such a local dynamic symbol.
With this change in effect we get:
$ readelf --dyn-syms pr21233
Symbol table '.dynsym' contains 2 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 00000000 0 NOTYPE LOCAL DEFAULT UND
1: 00000000 0 OBJECT GLOBAL DEFAULT UND bar
$
instead, for both targets.

Remove support for using the bsd-uthread target on FreeBSD.
The bsd-uthread target supports an old thread library ("libc_r") that
was last included in FreeBSD release 6.4 released in 2008. However,
this library has not been used as the default library since FreeBSD
5.0 (2003) and 4.11 (2005). Thread support for modern FreeBSD binaries
is provided via "normal" LWP support in core files and the native
FreeBSD target.

dwarf2read.c: C++fy lnp_state_machine
While I was looking at the file, I noticed that this struct could be
nicely converted to a class. As I was progressing, I ended up moving
all state machine actual internal state manipulation to methods of
lnp_state_machine, essentially decoupling DWARF parsing from state
tracking. I also noticed that the lnp_reader_state doesn't really
serve any good use, so that's eliminated in the process.

Make sect_offset and cu_offset strong typedefs instead of structs
A while ago, back when GDB was a C program, the sect_offset and
cu_offset types were made structs in order to prevent incorrect mixing
of those offsets. Now that we require C++11, we can make them
integers again, while keeping the safety, by exploiting "enum class".
We can add a bit more safety, even, by defining operators that the
types _should_ support, helping making the suspicious uses stand out
more.
Getting at the underlying type is done with the new to_underlying
function added by the previous patch, which also helps better spot
where do we need to step out of the safety net. Mostly, that's around
parsing the DWARF, and when we print the offset for complaint/debug
purposes. But there are other occasional uses.
Since we have to define the sect_offset/cu_offset types in a header
anyway, I went ahead and generalized/library-fied the idea of "offset"
types, making it trivial to add more such types if we find a use. See
common/offset-type.h and the DEFINE_OFFSET_TYPE macro.
I needed a couple generaly-useful preprocessor bits (e.g., yet another
CONCAT implementation), so I started a new common/preprocessor.h file.
I included units tests covering the "offset" types API. These are
mostly compile-time tests, using SFINAE to check that expressions that
shouldn't compile (e.g., comparing unrelated offset types) really are
invalid and would fail to compile. This same idea appeared in my
pending enum-flags revamp from a few months ago (though this version
is a bit further modernized compared to what I had posted), and I plan
on reusing the "check valid expression" bits added here in that
series, so I went ahead and defined the CHECK_VALID_EXPR macro in its
own header -- common/valid-expr.h. I think that's nicer regardless.
I was borderline between calling the new types "offset" types, or
"index" types, BTW. I stuck with "offset" simply because that's what
we're already calling them, mostly.

dwarf2read.c: Make dir_index and file_name_index strong typedefs
This should help catch mistakes related to mixing the 1-based DWARF
indexes with 0-based std::vector indexes, since the new types do not
implicitly convert to anything.
The change in read_formatted_entries relates to the fact that doing
the seemingly simpler:
- uintp = &fe.dir_index;
+ uintp = (unsigned int *) &fe.dir_index;
would be undefined C/C++. So to address that, I made the function
extract the form before assigning to the file_entry. It felt natural
to use gdb::optional for "do I have this value", and this is what
motivated the previous patch that added the missing observer methods
to gdb::optional.

gdb::optional: Add observers
Currently, gdb::optional is really minimal and can only be used for

std::optional.

dwarf2read.c: Some C++fycation, use std::vector, std::unique_ptr
This starts off as replacing a couple custom open coded vector
implementations in the file with std::vector, and then the rest falls
off of that. I.e., use new/delete instead of XCNEW/xfree, add
ctors/dtors/initializers where appropriate. And then use
std::unique_ptr instead of cleanups. Some functions became methods,
and in a couple spots, some single-use callback functions that would
have to be tweaked anyway are converted to lambdas instead.

Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX
Mark an ALLOC section, which should be placed in special memory area,
with SHF_GNU_MBIND. Its sh_info field indicates the special memory
type. GNU_MBIND section names start with ".mbind" so that they are
placed as orphan sections by linker. All input GNU_MBIND sections
with the same sh_type, sh_flags and sh_info are placed in one output
GNU_MBIND section. In executable and shared object, create a
GNU_MBIND segment for each GNU_MBIND section and its segment type is
PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is
aligned at page boundary.
The assembler syntax:
.section .mbind.foo,"adx",%progbits
^ 0: Special memory type.
|
'd' for SHF_GNU_MBIND.
.section .mbind.foo,"adx",%progbits,0x1

gas: xtensa: make trampolines relaxation work with jumps in slots other than 0
add_jump_to_trampoline assumes that jump instruction is in slot 0,
when it's in other slot that results in fixup that references NULL symbol,
which results in segfault later in xtensa_make_cached_fixup.
Search for the non-NULL symbol in the tc_frag_data.slot_symbols and check
that there's exactly one such slot.
xtensa_relax_frag for RELAX_TRAMPOLINE reassigns fixup from the original
instruction with jump to generated jump in the trampoline frag, but does not
fix its fx_r_type or fx_size. That results in "undecodable fix" or
"fixup not contained within frag" error messages during relaxation.
Fix both these fields.

2017-03-22 Max Filippov <jcmvbkbc@gmail.com>
* config/tc-xtensa.c (xtensa_relax_frag): Change fx_size of the
reassigned fixup to size of jump instruction (3) and fx_r_type
to BFD_RELOC_XTENSA_SLOT0_OP, as there's only one slot.
(add_jump_to_trampoline): Search
origfrag->tc_frag_data.slot_symbols for the slot with non-NULL
symbol and use that slot instead of slot 0.

Remove lwp -> pid conversion in linux_nat_xfer_partial
The linux_nat_xfer_partial does a conversion of inferior_ptid: if it's
an LWP (ptid::lwp != 0), it builds a new ptid with the lwp as
the pid and assigns that temporarily to inferior_ptid. For example, if
inferior_ptid is:
{ .pid = 1234, .lwp = 1235 }
it will assign this to inferior_ptid for the duration of the call:
{ .pid = 1235, .lwp = 0 }
Instead of doing this, this patch teaches the inf-ptrace implementation
of xfer_partial to deal with ptids representing lwps by using
get_ptrace_pid.
Also, in linux_proc_xfer_spu and linux_proc_xfer_partial, we use ptid_get_lwp
instead of ptid_get_pid. While not strictly necessary, since the content of
/proc/<pid> and /proc/<lwp> should be the same, it's a bit safer, because:
- some files under /proc/<pid>/ may not work if the <pid> thread is
running, just like ptrace requires a stopped thread. The current
thread's lwp id is more likely to be in the necessary state (stopped).
- if the leader (<pid>) had exited and is thus now zombie, then several
files under "/proc/<pid>" won't work, while they will if you use
"/proc/<lwp>".
The testsuite found no regression on native amd64 linux.
gdb/ChangeLog:
* inf-ptrace.c (inf_ptrace_xfer_partial): Get pid from ptid
using get_ptrace_pid.
* linux-nat.c (linux_nat_xfer_partial): Don't set/restore
inferior_ptid.
(linux_proc_xfer_partial, linux_proc_xfer_spu): Use lwp of
inferior_ptid instead of pid.

Wrap locally used classes in anonymous namespace
Both aarch64-tdep.c and arm-tdep.c defines a class instruction_reader, which
violates ODR, but linker doesn't an emit error. I fix this issue by wrapping
them by anonymous namespace, but I think it is better to apply this for all
locally used classes.
If it is a good idea to put locally used class into anonymous namespace, we
should document this rule into GDB coding convention, or even GCC coding
convention. Note that anonymous namespace has been used in GCC but GCC
coding convention doesn't mention the it.

windows: Use ptid from regcache in register fetch/store
Use the ptid from the regcache so we don't depend on the current value
of the inferior_ptid global.
Also, change how the current thread is passed to sub-functions. The
windows_fetch_inferior_registers function sets current_thread then calls
do_windows_fetch_inferior_registers, which reads current_thread. This
very much looks like passing a parameter through a global variable. I
think it would be more straightforward to pass the thread as a
parameter.
gdb/ChangeLog:
* windows-nat.c (do_windows_fetch_inferior_registers): Add
windows_thread_info parameter and use it instead of
current_thread.
(windows_fetch_inferior_registers): Don't set current_thread,
pass the thread to do_windows_fetch_inferior_registers. Use
ptid from regcache instead of inferior_ptid.
(do_windows_store_inferior_registers): Add windows_thread_info
parameter and use it instead of current_thread.
(windows_store_inferior_registers): Don't set current_thread,
pass the thread to do_windows_store_inferior_registers. Use
ptid from regcache instead of inferior_ptid.

Add rvalue reference tests and docs
This patch adds tests for the initial rvalue reference support patchset. All
of the new tests are practically mirrored regular references tests and, except
for the demangler ones, are introduced in new files, which are set to be
compiled with -std=gnu++11. Tested are printing of rvalue reference types and
values, rvalue reference parameters in function overloading, demangling of
function names containing rvalue reference parameters, casts to rvalue
reference types, application of the sizeof operator to rvalue reference types
and values, and support for rvalue references within the gdb python module.

Add rvalue references to overloading resolution
This patch introduces changes to rank_one_type() dealing with ranking an rvalue
reference type when selecting a best viable function from a set of candidate
functions. The 4 new added rules for rvalue references are:
1) An rvalue argument cannot be bound to a non-const lvalue reference parameter
and an lvalue argument cannot be bound to an rvalue reference parameter.
[C++11 13.3.3.1.4p3]
2) If a conversion to one type of reference is an identity conversion, and a
conversion to the second type of reference is a non-identity conversion, choose
the first type. [C++11 13.3.3.2p3]
3) An rvalue should be first tried to bind to an rvalue reference, and then to
an lvalue reference. [C++11 13.3.3.2p3]
4) An lvalue reference to a function gets higher priority than an rvalue
reference to a function. [C++11 13.3.3.2p3]
This patch is not exactly correct. See c++/15372 for tracking overload
resolution bugs.

Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression
semantics), lvalue and rvalue references are equivalent. That means that in all
but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE
check and, for switch statements, add a case label for a rvalue reference type
next to a case label for an lvalue reference type. This patch does exactly
that.

Add definitions for rvalue reference types
This patch introduces preliminal definitions regarding C++11 rvalue references
to the gdb type system. In addition to an enum type_code entry, a field in
struct type and an accessor macro for that which are created similarly to the
lvalue references counterparts, we also introduce a TYPE_REFERENCE convenience
macro used to check for both kinds of references simultaneously as they are
equivalent in many contexts.

Add -file-list-shared-libraries MI command
This change adds the MI equivalent for the "info sharedlibrary"
command. The command was already partially documented but ignored as
it was not implemented. The new MI command works similarly to the CLI
command, taking an optional regular expression as an argument and
outputting the library information.
I included a test for the new command in mi-solib.exp.

Fix spurious FAILs with examine-backward.exp
The test case examine-backward.exp issues the command "x/-s" after the end
of the first string in TestStrings, but without making sure that this

some random characters from before that string, and then the test fails.
This patch assures that TestStrings is preceded by a string terminator.

readelf: Don't error on .debug files with NOBITS .dynamic section.
The fix for PR binutils/17512 added a check for the dynamic segment being
inside the actual ELF file. If not an error message would be produced:
readelf: Error: the dynamic segment offset + size exceeds the size of the file
Unfortunately for separate debuginfo files it is common for the dynamic
segment not being inside the file because the .dynamic section is NOBITS.
Since the check is done unconditionally in process_program_headers and
process_program_headers is always called (to setup dynamic_addr in case
it is needed). The error is produced on any operations done on any .debug
file (even if no program headers or the dynamic segment is used).
If there are section headers then a cross check is done to see if the
.dynamic section is NOBITS in which case dynamic_addr is set to zero
without a warning or error (which is then checked first before any
operation on the dynamic segement is done).
Move the check for the dynamic segment being inside the actual ELF file
after the cross check with the section headers to suppress the error for
.debug files.
binutils/ChangeLog:
* readelf.c (process_program_headers): Move dynamic_addr check
after .dynamic section cross check.

s390: Fix displaced-stepping certain relative branch insns
On s390x targets GDB can not handle displaced stepping correctly for some
relative branch instructions, such as cij (compare immediate and branch
relative). When setting a breakpoint on such an instruction and
single-stepping over it, the branch is never taken. This is because the
check in s390_displaced_step_fixup for relative branch instructions is
incomplete.
Instead of completing the list of relative branch instructions to check
against, this patch just treats relative branches and non-branching
instructions in the same way and adjusts the PC with the negated
displacement in both cases.

* s390-linux-tdep.c (is_rsi, is_rie): Remove functions.

DT_TEXTREL vs IFUNC
If you should somehow link non-pic objects into a PIE or shared
library, resulting in an object with DT_TEXTREL (text relocations)
set, and your executable or shared library also contains GNU indirect
functions, then you're in trouble. To apply dynamic relocations
ld.so will make the text segment writable. On most systems this will
make the text segment non-executable, which will then result in a
segfault when ld.so tries to run ifunc resolvers when applying
relocations against ifuncs.
This patch teaches PowerPC ld to detect the situation, and warn.

PR remote/21188: Fix remote serial timeout
As Gareth McMullin <gareth@blacksphere.co.nz> reports at
<https://sourceware.org/ml/gdb-patches/2017-02/msg00560.html>, the
timeout mechanism in ser-unix.c was broken by commit 048094acc
("target remote: Don't rely on immediate_quit (introduce quit
handlers)").
Instead of applying a local fix, and since we now finally always use
interrupt_select [1], let's get rid of hardwire_readchar entirely, and
use ser_base_readchar instead, which has similar timeout handling,
except for the bug.
Smoke tested with:
$ socat -d -d pty,raw,echo=0 pty,raw,echo=0
2017/03/14 14:08:13 socat[4994] N PTY is /dev/pts/14
2017/03/14 14:08:13 socat[4994] N PTY is /dev/pts/15
2017/03/14 14:08:13 socat[4994] N starting data transfer loop with FDs [3,3] and [5,5]
$ gdbserver /dev/pts/14 PROG
$ gdb PROG -ex "tar rem /dev/pts/15"

Big-endian targets: Don't ignore offset into DW_OP_stack_value
Recently I fixed a bug that caused a DW_OP_implicit_pointer with non-zero
offset into a DW_OP_implicit_value to be handled incorrectly on big-endian
targets. GDB ignored the offset and copied the wrong bytes:
https://sourceware.org/ml/gdb-patches/2017-01/msg00251.html
But there is still a similar issue when a DW_OP_implicit_pointer points
into a DW_OP_stack_value instead; and again, the offset is ignored. There
is an important difference, though: While implicit values are treated like
blocks of data and anchored at the lowest-addressed byte, stack values
traditionally contain integer numbers and are anchored at the *least
significant* byte. Also, stack values do not come in varying sizes, but
are cut down appropriately when used. Thus, on big-endian targets the
scenario looks like this (higher addresses shown right):
|<- - - - - Stack value - - - - - - ->|
| |
|<- original object ->|
|
| offset ->|####|
^^^^
de-referenced
implicit pointer
(Note how the original object's size influences the position of the
de-referenced implicit pointer within the stack value. This is not the
case for little-endian targets, where the original object starts at offset
zero within the stack value.)
This patch implements the logic indicated in the above diagram and adds an
appropriate test case. A new function dwarf2_fetch_die_type_sect_off is
added; it is used for retrieving the original object's type, so its size
can be determined. That type is passed to dwarf2_evaluate_loc_desc_full
via a new parameter.
gdb/ChangeLog:
* dwarf2loc.c (indirect_synthetic_pointer): Get data type of
pointed-to DIE and pass it to dwarf2_evaluate_loc_desc_full.

Fix arm process record for some instructions
I look at some fails in gdb.reverse/solib-precsave.exp in -mthumb,

instructions, and fix these bugs by re-organizing the code to match
the table in ARM ARM.

gas/arc: Limit special handling of t/nt flag to ARCv2
In a later commit I'll be adding a new version of the ".nt" flag for an
ARC700 extension (NPS400) which does not require this same special

In this commit I have restricted the special flag handling to only apply
if we are assembling for ARCv2. This is a restructuring commit, and
there should be no user visible changes after this commit.
gas/ChangeLog:
* config/tc-arc.c (assemble_insn): Only handle ".t" and ".nt"

inf-ptrace: Do not stop memory transfers after a single word
When inf_ptrace_xfer_partial performs a memory transfer via ptrace with
PT_READ_I, PT_WRITE_I (aka PTRACE_PEEKTEXT, PTRACE_POKETEXT), etc., then
it currently transfers at most one word. This behavior yields degraded
performance, particularly if the caller has significant preparation work
for each invocation. And indeed it has for writing, in
memory_xfer_partial in target.c, where all of the remaining data to be
transferred is copied to a temporary buffer each time, for breakpoint
shadow handling. Thus large writes have quadratic runtime and can take
hours.
Note: On GNU/Linux targets GDB usually does not use
inf_ptrace_xfer_partial for large memory transfers, but attempts a single
read/write from/to /proc/<pid>/mem instead. However, the kernel may
reject writes to /proc/<pid>/mem (such as kernels prior to 2.6.39), or
/proc may not be mounted. In both cases GDB falls back to the ptrace
mechanism.
This patch fixes the performance issue by attempting to fulfill the whole
transfer request in inf_ptrace_xfer_partial, using a loop around the
ptrace call.
gdb/ChangeLog:
PR gdb/21220
* inf-ptrace.c (inf_ptrace_xfer_partial): In "case
TARGET_OBJECT_MEMORY", extract the logic for ptrace peek/poke...
(inf_ptrace_peek_poke): ...here. New function. Now also loop

An optional parameter TEST has been added to get_hexadecimal_valueof in commit:

This patch adds a similar optional parameter to other related methods that

Thus tests that evaluate same expression multiple times can provide custom

linux-nat: Exploit /proc/<pid>/mem for writing
So far linux_proc_xfer_partial refused to handle write requests. This is
still based on the assumption that the Linux kernel does not support
writes to /proc/<pid>/mem. That used to be true, but has changed with
Linux 2.6.39 released in May 2011.
This patch lifts this restriction and now exploits /proc/<pid>/mem for
writing to inferior memory as well, if possible.

* linux-nat.c (linux_proc_xfer_partial): Handle write operations
as well.

Add asserts in target_fetch/store_registers
We are currently assuming that regcache->ptid is equal to inferior_ptid
when we call target_fetch/store_registers. These asserts just validate
that assumption. Also, since the following patches will change target
code to use regcache->ptid instead of inferior_ptid, asserting that they
are the same should ensure that our changes don't have any unintended
consequences.
gdb/ChangeLog:
* target.c (target_fetch_registers, target_store_registers): Add
assert.

Introduce regcache_get_ptid
This patch introduces the regcache_get_ptid function, which can be used
to retrieve the ptid a regcache is connected to. It is used in
subsequent patches.

* regcache.c (regcache_get_ptid): New function.

testsuite: Disable backslash_in_multi_line_command_test for old DejaGnus
I noticed that backslash_in_multi_line_command_test in
gdb.base/commands.exp failed on our RHEL6 servers. I traced it to the
old version of DejaGnu (1.4.4). I have found that instead of receiving
the expected:
"print \\\nargc\n"
gdb received:
"print argc\n"
thus breaking the test and its purpose. Versionof DejaGnu < 1.5 mess
up sending "\\\n", it somehow gets replaced with a space. I found that
the following commit in DejaGnu fixed the issue:
http://git.savannah.gnu.org/cgit/dejagnu.git/commit/lib/remote.exp?id=3f39294f5cd6802858838d3bcc0ccce847ae17f2
Even though the commit is almost 10 years old, the following release of
DejaGnu was only in 2013, which is why we still have systems with the
old code.
If the DejaGnu version is < 1.5, we just skip the test.
gdb/testsuite/ChangeLog:
* gdb.base/commands.exp (backslash_in_multi_line_command_test):
Skip for versions of DejaGnu < 1.5.

testsuite: Introduce dejagnu_version
The next patch will require checking the DejaGnu version. There is
already a test that does this,
gdb.threads/attach-many-short-lived-threads.exp. This patch introduces
a new procedure, dejagnu_version, and makes that test use it.
The version number is "right-padded" with zeroes, to make sure that we
always return a triplet (major, minor, patch).
The procedure does not consider the DejaGnu versions from git. For
example, if you used DejaGnu from its current master branch, the version
would be "1.6.1-git", meaning that 1.6.1 will be the next release. I
figured we'll cross that bridge when (and if) we get there.
gdb/testsuite/ChangeLog:
* lib/gdb.exp (dejagnu_version): New proc.
* gdb.threads/attach-many-short-lived-threads.exp (bad_dejagnu):
Use dejagnu_version.

Merge libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.
While integrating the d_printing recursion guard change into gdb I
noticed we forgot to initialize the demangle_component d_printing
field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}.
As is done in cplus_demangle_fill_{component,builtin_type,operator}.
It happened to work because in gcc all demangle_components were
allocated through d_make_empty. But gdb has its own allocation
mechanism (as might other users).
libiberty/ChangeLog:
* cp-demangle.c (cplus_demangle_fill_name): Initialize
demangle_component d_printing.
(cplus_demangle_fill_extended_operator): Likewise.
(cplus_demangle_fill_ctor): Likewise.
(cplus_demangle_fill_dtor): Likewise.

* cp-name-parser.y (make_empty): Initialize d_printing to zero.

c++/8218: Destructors w/arguments.
For a long time now, c++/8218 has noted that GDB is printing argument types
for destructors:
(gdb) ptype A
type = class A {
public:
~A(int);
}
This happens because cp_type_print_method_args doesn't ignore artificial
arguments. [It ignores the first `this' pointer because it simply skips
the first argument for any non-static function.]
This patch fixes this:
(gdb) ptype A
type = class A {
public:
~A();
}
I've adjusted gdb.cp/templates.exp to account for this and added a new
passing regexp.

ld: Track changes to default region LMA even for empty sections
Given a linker script fragment like this:
SECTIONS {
. = 0x1000;
.text : AT(0x100) { *(.text) }
.data : AT(0x200) { *(.data) }
.rodata : AT(0x300) { *(.rodata) }
}
and an input file containing sections, '.text', '.data.1', and
'.rodata', then we'd expect the linker to place '.text' and '.rodata' in
the obvious way, and the '.data.1' orphan section would be located after
the '.data' section (assuming similar section properties).
Further, I believe that the expectation would be that the LMA for the
orphan '.data.1' section would start from 0x200 (as there is no '.data'
content).
However, right now, the LMA for '.data.1' would be 0x101, following on
from the '.text' section, this is because the change in LMA for the
'.data' section is not noticed by the linker, if there's no content in
the '.data' section.
What can be even more confusing to a user (though the cause is obvious
once you understand what's going on) is that adding some content to
'.data' will cause the orphan '.data.1' to switch to an LMA based off of
0x200.
This commit changes the behaviour so that an empty section that is in
the default lma region, and sets its lma, will adjust the lma of the
default region, this change will then be reflected in following sections
within the default lma memory region.
There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features. For now I've set the test to ignore these targets.

ld: better handling of lma region for orphan sections
When picking an lma_region for an orphan section we currently create a
new lang_output_section_statement_type and then populate this with the
orphan section.
The problem is that the lang_output_section_statement_type has a prev
pointer that links back to the previous output section. For non-orphan
output sections, that are created in linker script order, the prev
pointer will point to the output section that appears previous in linker
script order, as you'd probably expect.
The problem is that orphan sections are placed after processing the
linker script, and so, in the case of an output section created for an
orphan input section, the prev pointer actually points to the last
output section created.
This causes some unexpected behaviour when the orphan section is not
placed after the last non-orphan section that was created.
For example, consider this linker script:
MEMORY {
TEXT : ORIGIN = 0x200, LENGTH = 0x10
RODATA : ORIGIN = 0x400, LENGTH = 0x10
}
SECTIONS {
.text : {*(.text) } AT>TEXT
.data : AT(0x300) { *(.data) }
.rodata : { *(.rodata) } AT>RODATA
}
If we are processing an orphan section '.data.1' and decide to place
this after '.data', then the output section created will have a prev
pointer that references the '.rodata' output section. The result of
this is that '.data.1' will actually be assigned to the RODATA lma
region, which is probably not the expected behaviour.
The reason why '.data.1' is placed into the lma region of the '.rodata'
section is that lma region propagation is done at the time we create the
output section, based on the previous output section pointer, which is
really just a last-output-section-created pointer at that point in time,
though the prev point is fixed up later to reflect the true order of the
output sections.
The solution I propose in this commit is to move the propagation of lma
regions into a separate pass of the linker, rather than performing this
as part of the enter/exit of output sections during linker script
parsing.
During this later phase we have all of the output sections to hand, and
the prev/next points have been fixed up by this point to reflect the
actual placement ordering.
There's a new test to cover this issue that passes on a range of
targets, however, some targets generate additional sections, or have
stricter memory region size requirements that make it harder to come
up with a generic pass pattern, that still tests the required
features. For now I've set the test to ignore these targets.

X86: Add pseudo prefixes to control encoding
Many x86 instructions have more than one encodings. Assembler picks
the default one, usually the shortest one. Although the ".s", ".d8"
and ".d32" suffixes can be used to swap register operands or specify
displacement size, they aren't very flexible. This patch adds pseudo
prefixes, {xxx}, to control instruction encoding. The available
pseudo prefixes are {disp8}, {disp32}, {load}, {store}, {vex2}, {vex3}
and {evex}. Pseudo prefixes are preferred over the ".s", ".d8" and
".d32" suffixes, which are deprecated.

Fix PR18360 - internal error when using "interrupt -a"
If you do "interrupt -a" just while some thread is stepping over a
breakpoint, gdb trips on an internal error.
The test added by this patch manages to trigger this consistently by
spawning a few threads that are constantly tripping on a conditional
breakpoint whose condition always evaluates to false. With current
gdb, you get:
~~~
interrupt -a
.../src/gdb/inline-frame.c:343: internal-error: void skip_inline_frames(ptid_t): Assertion `find_inline_frame_state (ptid) == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/interrupt-while-step-over.exp: displaced-stepping=on: iter=0: interrupt -a (GDB internal error)
[...]
.../src/gdb/inline-frame.c:343: internal-error: void skip_inline_frames(ptid_t): Assertion `find_inline_frame_state (ptid) == NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.threads/interrupt-while-step-over.exp: displaced-stepping=off: iter=0: wait for stops (GDB internal error)
~~~
The assertion triggers because we're processing a stop for a thread
that had already stopped before and thus had already its inline-frame
state filled in.
Calling handle_inferior_event_1 directly within a
"thread_stop_requested" observer is something that I've wanted to get
rid of before, for being fragile. Nowadays, infrun is aware of
threads with pending events, so we can use that instead, and let the
normal fetch_inferior_event -> handle_inferior_event code path handle
the forced stop.
The change to finish_step_over is necessary because sometimes a thread
that was told to PTRACE_SINGLESTEP reports back a SIGSTOP instead of a
SIGTRAP (i.e., we tell it to single-step, and then interrupt it quick
enough that on the kernel side the thread dequeues the SIGTOP before
ever having had a chance of executing the instruction to be stepped).
SIGSTOP gets translated to a GDB_SIGNAL_0. And then finish_step_over
would miss calling clear_step_over_info, and thus miss restarting the
other threads (which in this case of threads with pending events,
means setting their "resumed" flag, so their pending events can be
consumed).
And now that we always restart threads in finish_step_over, we no
longer need to do that in handle_signal_stop.
Tested on x86_64 Fedora 23, native and gdbserver.

Fix PR 21218: GDB dumps core when escaping newline in multi-line command
With commit 3b12939dfc2399 ("Replace the sync_execution global with a
new enum prompt_state tristate"), GDB started aborting if you try
splitting an input line with a continuation char (backslash) while in
a multi-line command:
(gdb) commands
Type commands for breakpoint(s) 1, one per line.
End with a line saying just "end".
>print \
(gdb) 1 # note "(gdb)" incorrectly printed here.
>end
readline: readline_callback_read_char() called with no handler!
$
That abort is actually a symptom of an old problem introduced when
gdb_readline_wrapper was rewritten to use asynchronous readline, back
in 2007. Note how the "(gdb)" prompt is printed above in the "(gdb)
1" line. Clearly it shouldn't be there, but it already was before the
commit mentioned above. Fixing that also fixes the readline abort
shown above.
The problem starts when command_line_input passes a NULL prompt to
gdb_readline_wrapper when it finds previous incomplete input due to a
backslash, trying to fetch more input without printing another ">"
secondary prompt. That itself should not be a problem, because
passing NULL to gdb_readline_wrapper has the same meaning as passing a
pointer to empty string, since gdb_readline_wrapper exposes the same
interface as 'readline(char *)'. However, gdb_readline_wrapper passes
the prompt argument directly to display_gdb_prompt, and for the
latter, a NULL prompt argument has a different meaning - it requests
printing the primary prompt.
Before commit 782a7b8ef9c096 (which rewrote gdb_readline_wrapper to
use asynchronous readline), GDB behaved like this:
(gdb) commands
[....]
>print \
1
>end
(gdb)
The above is what this commit restores GDB back to.
New test included.

Fix PR tui/21216: TUI line breaks regression
Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make
ui_file a class hierarchy") regressed the TUI's command window.
Newlines miss doing a "carriage return", resulting in output like:
~~~~~~~~~~~~~~~~~~
(gdb) helpList of classes of commands:
aliases -- Aliases of other commands
breakpoints -- Making program stop at certain points
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Before the commit mentioned above, the default ui_file->to_write
implementation had a hack that would defer into the ui_file->to_fputs
method. The TUI's ui_file did not implement the to_write method, so
all writes would end up going to the ncurses window via tui_file_fputs
-> tui_puts.
After the commit above, the hack is gone, but the TUI's ui_file still
does not implement the ui_file::write method. Since tui_file inherits
from stdio_file, writing to a tui_file ends up doing fwrite on the
FILE stream the TUI is "associated" with, via stdio_file::write,
instead of writing to the ncurses window.
The fix is to have tui_file override the "write" method.
New test included.

Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make

regs", that leads gdb to crash when issuing:
./gdb ./a.out -ex 'layout regs' -ex start
From the backtrace, it's caused by this 'delete' on tui_restore_gdbout():

714 delete gdb_stdout;
The problem is simply that the commit mentioned above made the ui_file
that gdb_stdout is temporarily set to be a stack-allocated
string_file, while before it used to be a heap-allocated ui_file. The
fix is simply to remove the now-incorrect delete.
New test included, which exercises enabling all TUI layouts, with and
without execution. (This particular crash only triggers with
execution.)

amd64-mpx: initialize BND register before performing inferior calls.
This patch initializes the BND registers before executing the inferior
call. BND registers can be in arbitrary values at the moment of the
inferior call. In case the function being called uses as part of the
parameters BND register, e.g. when passing a pointer as parameter, the
current value of the register will be used. This can cause boundary
violations that are not due to a real bug or even desired by the user.
In this sense the best to be done is set the BND registers to allow
access to the whole memory, i.e. initialized state, before pushing the
inferior call.

Don't decode powerpc insns with invalid fields
Certain insns have restrictions on fields. For example, the insn
mentioned in the PR, lqarx, must specify an even general purpose
register as its destination and that register cannot appear in
either of the base or index reg fields. This holds even when the RA0
field is 0 (meaning a zero rather than r0).

gas: Emit name, comp_dir and producer strings in .debug_str.
Putting the name, comp_dir and producer strings in the .debug_str section
makes it possible to share them across CUs. This saves a small amount of

it easier for tools like rpm debugedit to adjust the source paths when
generating separate debuginfo files.

GAS: Fix bogus "attempt to move .org backwards" relaxation errors
Fix a commit 6afe8e98a664 ("internal error for backwards .org"),
<https://www.sourceware.org/ml/binutils/2008-06/msg00212.html>,
GAS regression that caused legitimate code to fail assembly with an
"attempt to move .org backwards" error.
For example with the `mips-linux' target we get:
$ cat org.s
.set mips16
la $2, foo
.org 0x1000
.align 2
foo:
.half 0
$ as -o org.o org.s
org.s: Assembler messages:
org.s:3: Error: attempt to move .org backwards
$
where the location pointer is obviously not moved backwards with `.org'.
The cause is positive `stretch' in relaxation due to a PC-relative ADDIU
instruction (produced from the LA macro used) getting expanded from 2 to
4 bytes as `foo' is noticed to be out of range for the short encoding.
This in turn triggers logic in `relax_segment' which concludes in the
processing of an `rs_org' frag produced that the location pointer is
moved backwards while in fact only the amount to space forward to the
location requested has shrunk, resulting in a negative growth of the
frag.
Correct the bad logic then and instead verify that the fixed part of an
`rs_org' frag has not overrun the location requested, as per the comment
already included with the error message:
/* Growth may be negative, but variable part of frag
cannot have fewer than 0 chars. That is, we can't
.org backwards. */
which accurately describes the regression scenario. Move the comment
ahead the conditional noted, for clarity.
Add generic and MIPS test cases for the `.org' pseudo-op, including the
test case discussed though not integrated with the offending commit in
particular, adjusted to work across all targets.

GDB: Add support for the new set/show disassembler-options commands.
This commit adds support to GDB so that it can modify the disassembler-options
value that is passed to the disassembler, similar to objdump's -M option.
Currently, the only supported targets are ARM, PowerPC and S/390, but
adding support for a new target(s) is not difficult.

x86: fix handling of 64-bit operand size VPCMPESTR{I,M}
Just like REX.W affects operand size of the implicit rAX/rDX inputs to
PCMPESTR{I,M}, VEX.W does for VPCMPESTR{I,M}. Allow Q or L suffixes on
the instructions.
Similarly the disassembler needs to be adjusted to no longer require
VEX.W to be zero for the instructions to be valid, and to emit proper
suffixes.
Note, however, that this doesn't address the problem of there being no
way to control (at least) {,E}VEX.W for 32- or 16-bit code. Nor does it
address the problem of the many WIG instructions not getting properly
disassembled when VEX.W=1.

Nios2 dynobj handling fixes
A number of places in elf32-nios.c created dynamic sections but didn't
set the hash table dynobj. That meant we could have duplicate dynamic
sections connected to a number of bfds, so size_dynamic_sections
didn't properly discard or allocate contents.
Also, the entire set of dynamic sections was created in check_relocs
on seeing GOT relocs, when only .got related sections are needed,
probably done to hide segfaults later in finish_dynamic_sections.
The patch fixes these issues and makes the assembler emit errors when
nios2 lacks the necessary pc-relative relocs for subtraction
expressions, rather than silently generating bad code.
eg. ld-elf/merge. I've also tidied uses of elf32_nios2_hash_table and
elf_hash_table.

PowerPC addpcis fix
This came up because I was looking at ld/tmpdir/addpcis.o and noticed
the odd addends on REL16DX_HA. They ought to both be -4. The error
crept in due REL16DX_HA howto being pc-relative (as indeed it should
be), and code at gas/write.c:1001 after this comment
/* Make it pc-relative. If the back-end code has not
selected a pc-relative reloc, cancel the adjustment
we do later on all pc-relative relocs. */
*not* cancelling the pc-relative adjustment. So I've made a dummy
non-relative split reloc so that the generic code handles this, rather
than attempting to add hacks later in md_apply_fix which would not be
very robust. Having the new internal reloc also makes it easy to
support
addpcis rx,sym@ha
as an equivalent to
addpcis rx,(sym-0f)@ha
0:
The patch also fixes overflow checking, which must test whether the
addi will overflow too since @l relocs don't have any overflow check.
Lastly, since I was poking at md_apply_fix, I arranged to have the
generic gas/write.c code emit errors for subtraction expressions where
we lack reloc support.

Don't make dynamic .data.rel.ro SEC_READONLY
I'd made this dynamic section read-only so a flag test distinguished
it from .dynbss, but like any other .data.rel.ro section it really
should be marked read-write. (It is read-only after relocation, not
before.) When using the standard linker scripts this usually doesn't
matter since the output section is among other read-write sections and
not page aligned. However, it might matter in the extraordinary case
of the dynamic section being the only .data.rel.ro section with the
output section just happening to be page aligned and a multiple of a
page in size. In that case the output section would be read-only, and
live it its own read-only PT_LOAD segment, which is incorrect.
