DWARF-5: .debug_names index consumer
Hi,
it is not regression-free against no-index but it is regression-free against
.gdb_index. That is because .gdb_index is not regression-free against
no-index.
Some testcases needed to be updated as they were missing .debug_aranges.
While that does not matter for no-index (as GDB builds the mapping internally
during dwarf2_build_psymtabs_hard) and neither for .gdb_index (as GDB uses that
internally built mapping which it stores into .gdb_index) it does matter for
.debug_names as that simply assumes existing .debug_aranges from GCC.
I tried some performance checking but the index handling speed is negligible
compared to the CU expansion associated with it. .debug_names looked even as
a bit faster to me than .gdb_index which rather surprised me but I did not
investigate it more.

DWARF-5: .debug_names index producer
Hi,
there are two FIXME lines I do not have a real answer for.
Also I am not sure if the -dwarf-4 option for former .gdb_index should be named
that way. And contrib/gdb-add-index.sh (incl. cc-with-tweaks.sh) has no
commandline option for that -dwarf-4 GDB option.

cc-with-tweaks.sh: Use gdb-add-index.sh
Hi,
currently contrib/cc-with-tweaks.sh is calling for its -i option objcopy itself
instead of using contrib/gdb-add-index.sh which does the same.
With DWARF-5 .debug_names the commands are more complicated (as now also
.debug_str needs to be modified) and so I have decided to rather reuse
contrib/gdb-add-index.sh instead of duplicating its code
in contrib/cc-with-tweaks.sh.
The problem is when no index is produced whether contrib/cc-with-tweaks.sh
should fail or not. As originally contrib/cc-with-tweaks.sh was more quiet
(=successful) than contrib/gdb-add-index.sh and so after this patch the
testsuite runs with an index would "regress". I have tried to keep the
behavior unchanged. Some cases still error with:
Ada is not currently supported by the index
But some cases (such as some trivial gdb.dwarf2/ testcases with no DWARF data
to index) produce no index while the testcases still PASS now instead of:
-PASS: gdb.arch/i386-bp_permanent.exp: stack pointer value matches
+gdb compile failed, gdb-add-index.sh: No index was created for /quadgdb/testsuite.unix.-m64/outputs/gdb.arch/i386-bp_permanent/i386-bp_permanent
+gdb-add-index.sh: [Was there no debuginfo? Was there already an index?]
+UNTESTED: gdb.arch/i386-bp_permanent.exp: failed to compile

gdb/command.h: Include common/scoped_restore.h
command.h depends on scoped_restore:
extern scoped_restore_tmpl<int> prevent_dont_repeat (void);
But doesn't include the corresponding header
("common/scoped_restore.h"). We haven't noticed a problem because
utils.h includes scoped_restore.h, and defs.h includes utils.h.
However, a patch that makes "symtab.h" include "completer.h", exposed
the issue:
https://sourceware.org/ml/gdb-patches/2017-06/msg00023.html.
Without this fix that would break building all .o files like this:
In file included from src/gdb/completer.h:21:0,

because defs.h includes gdbarch.h before it includes utils.h.

Fix PR 21337: segfault when re-reading symbols.
Fix issue exposed by commit 3e29f34.
The basic issue is that section data referenced through an objfile
pointer can also be referenced via the program-space data pointer,
although via a separate mapping mechanism, which is set up by
update_section_map. Thus once section data attached to an objfile
pointer is released, the section map associated with the program-space
data pointer must be marked dirty to ensure that update_section_map is
called to prevent stale data being referenced. For the matter at hand
this marking is being done via a call to objfiles_changed.
Before commit 3e29f34 objfiles_changed could be called after all of
the objfile pointers were processed in reread_symbols since section
data references via the program-space data pointer would not occur in
the calls of read_symbols performed by reread_symbols.
With commit 3e29f34 MIPS target specific calls to find_pc_section were
added to the code for DWARF information processing, which is called
via read_symbols. Thus in reread_symbols the call to objfiles_changed
needs to be called before calling read_symbols, otherwise stale
section data can be referenced.
Thanks to Luis Machado for providing text for the main comment
associated with the change.

MIPS: Add Imagination interAptiv MR2 MIPS32r3 processor support
Add support for the Imagination interAptiv MR2 MIPS32r3 processor with
the MIPS16e2 ASE as per documentation, including in particular:
1. Support for implementation-specific interAptiv MR2 COPYW and UCOPYW
MIPS16e2 instructions[1], for assembly and disassembly,
2. Support for implementation-specific interAptiv MR2 SAVE and RESTORE
regular MIPS instructions[2], for assembly and disassembly,
3. ELF binary file annotation for the interAptiv MR2 MIPS architecture
extension.
4. Support for interAptiv MR2 architecture selection for assembly, in
the form of the `-march=interaptiv-mr2' command-line option and its
corresponding `arch=interaptiv-mr2' setting for the `.set' and
`.module' pseudo-ops.
5. Support for interAptiv MR2 architecture selection for disassembly,
in the form of the `mips:interaptiv-mr2' target architecture, for
use e.g. with the `-m' command-line option for `objdump'.

objfile_per_bfd_storage non-POD
A following patch will want to add a std::vector to
objfile_per_bfd_storage. That makes it non-trivially
constructible/destructible. Since objfile_per_bfd_storage objects are
allocated on an obstack, we need to call their ctors/dtors manually.
This is what this patch does. And then since we can now rely on
ctors/dtors being run, make objfile_per_bfd_storage::storage_obstack
be an auto_obstack.

Eliminate make_cleanup_obstack_free, introduce auto_obstack
This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.
These changes in the parsers may not be obvious:
- obstack_init (&name_obstack);
- make_cleanup_obstack_free (&name_obstack);
+ name_obstack.clear ();
Here, the 'name_obstack' variable is a global. The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts. I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.
The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases. I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

Fix PR 13402
Fix incorrect adjustment of diff relocs when relaxing, and thus the
resulting source line to address mismatch.
Fix two issues when adjusting diff relocs to account for
deleted bytes.
1. Don't adjust the difference if the end address is the shrinked
insn's address i.e. use < instead of <=. The relaxation code deletes
count bytes from or after shrinked_insn_address, so the difference
between start_address and end_address should remain unchanged in this
case.
2. Adjust the reloc addend if the difference is to be adjusted and
symval + reloc addend is past the shrinked insn address. This is
because for a typical sym1 - sym2 diff reloc, sym1 is .text +
irel->r_addend, and the addend should be reduced to account for the
shrinked insn.
For example, assume the reloc value is .text + 0x8 with .text = 0, the
diff value in the object file = 0x4, and shrinked_insn_address = 0x4
with count = 0x2. Then the existing code writes 0x2 into the object
file to account for the deleted bytes, as shrinked_insn_address lies
between 0x8 and 0x8 - 0x4 = 0x4, but leaves the addend as is. The next
time the reloc is looked at, the code sees if a shrinked_insn_address
lies between 0x8 and 0x8 - 0x2 = 0x6, instead of 0x6 and 0x4. If there
happens to be one, then the diff value in the object file ends up
getting reduced again.

/Users/simark/src/binutils-gdb/gdb/darwin-nat.c:383: internal-error: void darwin_check_new_threads(struct inferior *): Assertion `tp' failed.
with the corresponding partial backtrace (sorry, taken with lldb,
because well, gdb is broken :)):

The issue was introduced by commit
"Share fork_inferior et al with gdbserver"
because it changed the place where the dummy thread (pid, 0, 0) is added,
relative to the call to the init_trace_fun callback. In this callback, darwin
checks for new threads in the program (there should be exactly one) in order to
update this dummy thread with the right tid. Previously, things happened in
this order:
- fork_inferior calls fork()
- fork_inferior adds dummy thread
- fork_inferior calls init_trace_fun callback, which updates the dummy
thread info
Following the commit mentioned above, the new thread is added in the
darwin-nat code, after having called fork_inferior (in
darwin_create_inferior). So gdb tries to do things in this order:
- fork_inferior calls fork()
- fork_inferior calls init_trace_fun callback, which tries to update
the dummy thread info
- darwin_create_inferior adds the dummy thread
The error happens while trying to update the dummy thread that has not
been added yet.
I don't think this dummy thread is necessary for darwin. Previously, it
was fork_inferior that was adding this thread, for all targets, so
darwin had to deal with it. Now that it's done by targets themselves,
we can just skip that on darwin. darwin_check_new_threads called
indirectly by init_trace_fun/darwin_ptrace_him will simply notice the
new thread and add it with the right information.
My level of testing was: try to start a process and try to attach to a
process, and it seems to work somewhat like it did before. I tried to
run the testsuite, but it leaves a huge amount of zombie processes that
launchd doesn't seem to reap, leading to exhaustion of system resources
(number of processes).
gdb/ChangeLog:
* darwin-nat.c (darwin_check_new_threads): Don't handle dummy
thread.
(darwin_init_thread_list): Don't update dummy thread.
(darwin_create_inferior, darwin_attach): Don't add a dummy thread.

MIPS/LD/testsuite: mips-elf-flags: Add MIPS ABI Flags handling
Complement commit 351cdf24d223 ("[MIPS] Implement O32 FPXX, FP64 and
FP64A ABI extensions") and add optional MIPS ABI Flags handling to
`good_combination' in the `mips-elf-flags.exp' test script. This lets
callers of this procedure request to examine MIPS ABI Flags in addition
to the `e_flags' member of the ELF file header so as to verify that
flags are merged correctly by LD. The presence of further arguments
triggers this verification, in which case `readelf' is called with the
`-A' option additionally specified and the ISA member, the ISA Extension
member and the ASEs member will be examined as per the arguments.
Unlike with `readelf -h' output consider a failure to retrieve the
member requested a test case failure rather than an unresolved result.
This is because unlike with the `e_flags' member of the ELF file header
which is always there in any valid ELF file the MIPS ABI Flags structure
is optional in LD output and the absence of this structure when expected
is surely a bug in LD.
ld/
* testsuite/ld-mips-elf/mips-elf-flags.exp (good_combination):
Add an `args' final argument and examination code for `readelf
-A' output. Update procedure description accordingly.

MIPS/LD/testsuite: mips-elf-flags: Use `remote_exec' to call `readelf'
For ELF file header flag verification done in `good_combination' in the
`mips-elf-flags.exp' test script the version of `readelf' built along
with the rest of binutils has to be used rather than any such executable
already present on the build system, so that flags recognized by the
tool match those supported by LD being tested. Use `remote_exec' as
elsewhere in the LD test framework and also with GAS and LD used here,
getting and arranging for extra reporting of `readelf' calls included in
test logs on this occasion as well.

For the purpose of link-time object compatibility handling verification

test script only examines the `e_flags' member of the ELF file header
and ignores data from any ELF program or section headers present. Use
`readelf -h' rather than `readelf --headers' then to obtain data for
examination, avoiding unnecessary processing to extract this extraneous
information.

Available documentation[1][2] clearly indicates the LSI CW4010 processor
is only backwards compatible with the MIPS R4000 processor as far as the
latter's 32-bit instructions are concerned and consequently can only be
considered a MIPS II ISA implementation (with vendor extensions).
This fixes an LD testsuite failure:
FAIL: MIPS incompatible objects: "-march=r4010 -32" "-march=r4650 -32"
triggered for the `mips-sgi-irix5' and `mips-sgi-irix6' targets.

LD: Fix .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX
Correct .startof.SECNAME/.sizeof.SECNAME tests for MIPS/IRIX targets,
complementing commit dc74becf498f ("ld: Add tests for -Ur") and commit
da614360f520 ("ld: Add tests for .startof.SECNAME/.sizeof.SECNAME") with
subsequent updates, and in reference to commit cbd0eecf261c ("Always
define referenced __start_SECNAME/__stop_SECNAME") and commit
7dba9362c172 ("Rewrite __start and __stop symbol handling").
These targets set the STT_OBJECT type for non-function symbol
references, according to `elf_frob_symbol' code in gas/config/obj-elf.c:
/* The Irix 5 and 6 assemblers set the type of any common symbol and
any undefined non-function symbol to STT_OBJECT. We try to be
compatible, since newer Irix 5 and 6 linkers care. However, we
only set undefined symbols to be STT_OBJECT if we are on Irix,
because that is the only time gcc will generate the necessary
.global directives to mark functions. */
if (S_IS_COMMON (symp))
symbol_get_bfdsym (symp)->flags |= BSF_OBJECT;
if (strstr (TARGET_OS, "irix") != NULL
&& ! S_IS_DEFINED (symp)
&& (symbol_get_bfdsym (symp)->flags & BSF_FUNCTION) == 0)
symbol_get_bfdsym (symp)->flags |= BSF_OBJECT;
and consequently entries in the symbol table listing from `readelf'
produced with these tests do not match the NOTYPE pattern expected,
causing test suite failures:

FAIL: ld-elf/sizeofc
FAIL: ld-elf/startofa
FAIL: ld-elf/startofc
specifically with the `mips-sgi-irix5' and `mips-sgi-irix6' targets.
Given that it does not matter for the feature covered by these tests
whether the type of the symbols produced is STT_NOTYPE or STT_OBJECT
adjust the problematic cases to accept either type, removing the
failures observed.

netorder16 (uint16_t input)

Remove this function, which, AFAIK, has never been used. Note that GCC
doesn't warn about this, because the function is marked as inline.
According to gcc's man page, it should ideed not warn:
-Wunused-function
Warn whenever a static function is declared but not defined or a non-inline static function is unused. This warning is enabled by -Wall.
So it's probably not a GCC bug that it doesn't find this unused function, but a
different definition of "unused".

vec: Silence -Wunused-function warnings on clang
clang has a too aggressive (or broken, depends on how you want to see
it) -Wunused-function warning, which is triggered by the functions
defined by DEF_VEC_* but not used in the current source file. Normally,
it won't warn about unused static inline functions defined in header
files, because it's expected that a source file won't use all functions
defined in a header file it includes. However, if the DEF_VEC_* macro
is used in a source file, it considers those functions as defined in the
source file, which leads it to think that we should remove those
functions. It is therefore missing a check to see whether those
functions are resulting from macro expansion. A bug already exists for
that:
https://bugs.llvm.org//show_bug.cgi?id=22712
It's quite easy to silence this warning in a localized way, that is in
the DEF_VEC_* macros.

Don't attach linker created section to --just-syms bfd
All sections on a --just-syms bfd are discarded from the output, so
attaching linker created sections to such a bfd results in errors.

It's quite easy to get rid of it by using &foo[len] instead of foo + len.
I think this warning is relevant to keep enabled, because it can be an
easy mistake to do.
This warning is already discussed here in GCC bugzilla:

Putting the semicolon on its own line is not a big sacrifice to get rid of this
warning. I think it's also useful to keep this, because it can catch errors
like this:
while (something);

although gcc would warn about it in a different way (misleading indentation).

[ARM] Add linker support for ARMv8-R
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in the linker.
=== Patch description ===
This patch is composed of 3 changes:
1) The main change is the addition of the logic for merging a file whose
Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are
merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into
ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to
merge merge with ARMv8-R. Note that merging only occurs if the two
profiles are identical or one is S (Application or Realtime) and the
other is R.
2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop
are updated according to capabilities of ARMv8-R and their BFD_ASSERT
updated to reflect that the logic is valid for ARMv8-R.
3) 2 build attribute merging tests are added to test the first change.

[ARM] Add support for ARMv8-R in assembler and readelf
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to add support for ARMv8-R in GAS:
instructions, build attributes and readelf.
=== Patch description ===
Although some differences exist for system registers, from GAS point of
view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state
and a subset of its extensions. This patch therefore introduce a new
feature bit to distinguish the availability of the pan, ras and rdma
extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd
extensions to be used by ARMv8-R.
Most of the changes are then in the testsuite to (i) rename source files
and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename
files with expected output for ARMv8-A build attributes and (iii) add
new files with expected output for ARMv8-R build attributes.

[ARM] Remove ARMv6S-M special casing
=== Context ===
This patch is part of a patch series to add support for ARMv8-R
architecture. Its purpose is to remove special casing for ARMv6S-M
autodetection.
=== Motivation ===
Currently, SWI and SVC mnemonics are enabled for ARMv4T and successor
architectures with extra checks in the handler function (do_t_swi) to
give an error message when ARMv6-M is targeted and some more special
casing in aeabi_set_public_attributes. This was made to exclude these
mnemonics for ARMv6-M unless the OS extension is in use.
However this logic is superfluous: there is already code to check
whether an instruction is available based on the feature bit it is part
of and whether the targeted architecture has that feature bit. This
patch aims at removing that unneeded complexity.
=== Patch description ===
The OS extension is already limited to the ARMv6-M architecture so all
this patch does is redefined availability of the ARM_EXT_OS feature bit
to not be present for ARM_ARCH_V6M. ARM_ARCH_V6SM does not need any
change either because it already includes ARM_EXT_OS.
The patch also make sure that the error message that was given by
do_t_swi when SWI/SVC is unavailable is still the same by detecting the
situation in md_assemble.

[GOLD] PowerPC64 tocsave
This adds support to gold for the tocsave relocs already supported by
ld.bfd. R_PPC64_TOCSAVE relocs are part of a scheme to move r2 saves
to the prologue of a function rather than in each plt call stub. We
don't want a compiler to always emit the r2 save, as this would be
wasted if the calls turned out to be local. See the tocsave*.s in
ld/testsuite/ld-powerpc/.
* powerpc.cc (Target_powerpc::tocsave_loc_): New var.
(Target_powerpc::mark_pltcall, add_tocsave, tocsave_loc): New functions.
(Target_powerpc::Branch_info::tocsave_): New var.

(Target_powerpc::Branch_info::make_stub): Pass tocsave_ to
add_plt_call_entry.
(Stub_table::Plt_stub_ent): Make public. Add r2save_.
(Stub_table::add_plt_call_entry): Add bool tocsave_ param. Set
r2save_.
(Stub_table::find_plt_call_entry): Return Plt_stub_ent*. Adjust
use throughout.
(Stub_table::do_write): Conditionally output r2 save in plt stubs.
(Target_powerpc::Scan::local): Handle R_PPC64_TOCSAVE.
(Target_powerpc::Scan::global): Likewise.
(Target_powerpc::Relocate::relocate): Skip r2 save in plt call stub
with tocsave reloc. Replace header tocsave nop with r2 save.

x86-64: Move the error_alignment label forward
Move the error_alignment label forward to avoid clang warning on
if (!bfd_set_section_alignment (ebfd, sec, 2))
goto error_alignment;
htab = elf_x86_64_hash_table (info);
error_alignment:
info->callbacks->einfo (_("%F%A: failed to align section\n"), sec);
"%F" causes a fatal linker error and
immediate exit.
sec = htab->elf.sgotplt;
Also fix alignment on program property note section.
* elf64-x86-64.c (elf_x86_64_link_setup_gnu_properties): Move
