Fix TAB-completion + .gdb_index slowness (generalize filename_seen_cache)
Tab completion when debugging a program binary that uses GDB index is
surprisingly much slower than when GDB uses psymtabs instead. Around
1.5x/3x slower. That's surprising, because the whole point of GDB
index is to speed things up...
For example, with:
set pagination off
set $count = 0
while $count < 400
complete b string_prin # matches gdb's string_printf
printf "count = %d\n", $count
set $count = $count + 1
end
$ time ./gdb --batch -q ./gdb-with-index -ex "source script.cmd"
real 0m11.042s
user 0m10.920s
sys 0m0.042s
$ time ./gdb --batch -q ./gdb-without-index -ex "source script.cmd"
real 0m4.635s
user 0m4.590s
sys 0m0.037s
Same but with:
- complete b string_prin
+ complete b zzzzzz
to exercise the no-matches worst case, master currently gets you
something like:
with index without index
real 0m11.971s 0m8.413s
user 0m11.912s 0m8.355s
sys 0m0.035s 0m0.035s
Running gdb under perf shows 80% spent inside
maybe_add_partial_symtab_filename, and 20% spent in the lbasename
inside that.
The problem that tab completion walks over all compunit symtabs, and
for each, walks the contained file symtabs. And there a huge number
of file symtabs (each included system header, etc.) that appear in
each compunit symtab's file symtab list. As in, when debugging GDB, I
have 367381 symtabs iterated, when of those only 5371 filenames are
unique...
This was a regression from the earlier (nice) split of symtabs in
compunit symtabs + file symtabs.
The fix here is to add a cache of unique filenames per objfile so that
the walk / uniquing is only done once. There's already a abstraction
for this in symtab.c; this patch moves that code out to a separate
file and C++ifies it bit.
This makes the worst-case scenario above consistently drop to ~2.5s
(1.5s for the "string_prin" hit case), making it over 3.3x times
faster than psymtabs in this use case (7x in the "string_prin" hit
case).

__tls_get_addr_opt GOT entries
My 2017-01-24 patch (commit
f0158f44) wrongly applied an optimization
of GOT entries for the __tls_get_addr_opt stub, to shared libraries.
When the TLS segment layout is known, as it is for the executable and
shared libraries loaded at initial program start, powerpc supports a
__tls_get_addr optimization. On the first call to __tls_get_addr for
a given __tls_index GOT entry, the DTPMOD word is set to zero and the
DTPREL word to the thread pointer offset to the thread variable. This
allows the __tls_get_addr_opt stub to return that value immediately
without making a call into glibc for any subsequent __tls_get_addr
calls using that __tls_index GOT entry.
That's all fine, but I thought I'd be clever and when the thread
variable is local, set up the GOT entry as if __tls_get_addr had
already been called. Which is good only for the executable, since ld
cannot know the TLS layout for shared libraries.
Of course, if this only applies to executables there isn't much point
to the optimization. Normally, GD and LD code in an executable will
be converted to IE or LE, losing the __tls_get_addr call. So the only
time it will trigger is with --no-tls-optimize. Thus, revert all
support.

AMD64_FSBASE_REGNUM, "fs_base");
tdesc_numbered_register (feature, tdesc_data_segments,
AMD64_GSBASE_REGNUM, "gs_base");
and that happens because amd64_linux_init_abi uses amd64_init_abi as
helper, but they don't coordinate on which fallback tdesc to use.
amd64_init_abi does:
if (! tdesc_has_registers (tdesc))
tdesc = tdesc_amd64;
and then adds the fs_base/gs_base registers of the "tdesc_amd64" tdesc
to the tdesc_arch_data.
After amd64_init_abi returns, amd64_linux_init_abi does:
if (! tdesc_has_registers (tdesc))
tdesc = tdesc_amd64_linux;
tdep->tdesc = tdesc;
and we end up tdesc_amd64_linux installed in tdep->tdesc.
The fix is to make sure that amd64_linux_init_abi and amd64_init_abi
agree on default tdesc, by adding a "default tdesc" parameter to
amd64_init_abi, instead of having amd64_init_abi hardcode a default.
With this, amd64_init_abi creates the fs_base/gs_base registers using
the tdesc_amd64_linux tdesc.
Tested on x86-64 GNU/Linux, -m64. I don't have an x32 setup handy.
Thanks to John Baldwin, Yao Qi and Simon Marchi for the investigation.

Fixing for PR gold/21491 - Errata workaround can produce broken images.
The problem is caused by the fact that gold is relocating the stubs
for an entire output section when it processes the relocations for a
particular input section that happened to be designated as the stub
table "owner". The Relocate_task for that input section may or may not
run before the Relocate_task for another input section that contains
the code that needs the erratum fix, but doesn't "own" the stub
table. If it runs before (or might even race with) that other task, it
ends up with a copy of the unrelocated original instruction.
In other words - when calling fix_errata() from
do_relocate_sections(), gold is going through the list of errata stubs
that are associated only with that object. This routine updates the
stored original instruction and replaces it in the output view with a
branch to the stub. Later, as gold is going through the object file's
input sections, it then checks for stub tables "owned" by each input
section, and writes out all the stubs from that stub table, regardless
of what object file each stub is associated with.
Fixed by relocating the erratum stub only after the corresponding
errata spot is fixed. That is to have fix_errata() call
Stub_table::relocate_erratum_stub() for each stub.

I am really not sure if what this patch does is good, but it is my best
guess. DW_OP_addr means that there's an constant address provided by
the DWARF bytecode that should be pushed on the stack. That address is
considered skipped by the "op_ptr += addr_size", but it is never read.
uoffset is indeed read just after, without having been assigned first.
So I think the intent is to read the address, it was just omitted.

Fix size check in dwarf2_evaluate_loc_desc_full
This Rust bug report:
https://github.com/rust-lang/rust/issues/41970
noted an error from gdb. What is happening here (for me, the original
report had a different error) is that a pieced DWARF expression is not
writing to every byte in the resulting value. GDB errors in this
case. However, it seems to me that it is always valid to write fewer
bytes; the issue comes from writing too many -- that is, the test is
reversed. The test was also checking the sub-object, but this also
seems incorrect, as it's expected for the expression to write the
entirety of the enclosing object. So, this patch reverses the test
and applies it to the outer type, not the subobject type.
Regtested on the buildbot.

MIPS/LD: Fix a segfault from ELF `e_flags' access with non-ELF output BFD
Fix a commit
861fb55ab50a ("Defer allocation of R_MIPS_REL32 GOT
slots"), <https://sourceware.org/ml/binutils/2008-08/msg00096.html>,
regression and a more recent:
FAIL: ld-unique/pr21529
new LD test case failure, observed with all the relevant MIPS targets
whenever the linker is invoked with one or more ELF inputs and the
output format set to `binary'.
The culprit is a segmentation fault caused in `mips_before_allocation'
by a null pointer dereference, where an attempt is made to access the
ELF file header's `e_flags' member, for the purpose of determining
whether to produce a PLT and copy relocations, without first checking
that the output BFD is ELF. The `e_flags' member is stored in BFD's
private data pointed to by `tdep', which in the case of the `binary' BFD
is null, causing the segmentation fault. With other non-ELF BFDs such
as SREC `tdep' is not null and consequently no crash may happen and in
that case random data will be interpreted as it was `e_flags'.
Disable the access to `e_flags' then and all the associated checks and
consequently never produce a PLT and copy relocations if output is not a
MIPS ELF BFD, matching `_bfd_mips_elf_merge_private_bfd_data' that does
not process `e_flags' in that case either and therefore does not let us
decide here anyway if all the input objects included in the link are
suitable for use with a PLT and copy relocations.

Fission support for multiple CUs per DWO file
In some cases a compiler may produce a single object file (& thus single
DWO file) representing multiple source files. The most common example of
this is in whole program optimization (such as LLVM's LTO). Fission may
still be a beneficial feature to use here - to avoid the need to
read/link the debug info with system libraries and the like.
This change adds basic support for multiple CUs in a single DWO file to
support LLVM's output in this situation.
There is still outstanding work to design and implement a solution for
cross-CU references (usually using DW_FORM_ref_addr) in this scenario.
For now LLVM works around this by duplicating DIEs rather than making
cross-CU references in DWO files. This degrades debugger
behavior/quality especially for file-local entities.

Fix Python unwinder frames regression
The gdb.python/py-unwind.exp test is crashing GDB / leaving core dumps
in the test dir, even though it all passes cleanly. The crash is not
visible in gdb.sum/gdb.log because it happens as side effect of the
"quit" command, while flushing the frame cache.
The problem is simply a typo in a 'for' loop's condition, introduced
by a recent change [
4fa847d78edd ("Remove MAX_REGISTER_SIZE from
py-unwind.c")], resulting in infinite loop / double-free.
The new test exposes the crash, like:

[ARM] Add support for Cortex-A55 and Cortex-A75.
This patch adds support for the ARM Cortex-A55 and
Cortex-A75 processors.
The ARM Cortex-A55 and Cortex-A75 procsessors implement the ARMv8-A
architecture, with support for the ARMv8.1-A and ARMv8.2-A extensions,
including support for the 16-bit floating point extensions.
The 16-bit floating-point extensions are optional, and we haven't defined
an option mapping straight to them thus far, so this patch first needs to
add one of those in include/opcode/arm.h, then we can simply add the CPU names
as usual in config/tc-arm.c .
Tested on arm-none-eabi.

[AArch64] Remove useless and incorrect assertion
The outer caller elf_link_output_extsym in elflink.c is a traverse function on
all external symbol, and it will only call *finish_dynamic_symbol if some
conditions is meet. It is executed conditionally.
If the condition to trigger that assertion is satisified, it then won't satify
the outer check in finish_dynamic_symbol, so *finish_dynamic_symbol won't be
called that the assertion is expected to be dead code.
If elf_link_output_extsym is a traverse function that unconditionally called

strings: remove section/file size check
This reverts most of
06803313754, 2005-07-05 Dmitry V. Levin change

seen recently with mmo tests, decoded section size can easily exceed
file size with formats that encode section data.

"strings" won't die on a malloc failure. I think it's better to
continue on looking at other sections after failing to dump a section

Support %Lx, %Lu, %Ld in _bfd_error_handler format
One way to print 64-bit bfd_vma or bfd_size_type values on 32-bit
hosts is to cast the value to long long and use the 'll' modifier in
printf format strings. However, that's awkward because we also
support the Microsoft C library printf that uses 'I64' as a modifier
instead, and having variants of translated strings would not endear us
to the translation project. So, rewrite the 'll' modifier in
_doprint for Microsoft. Even with that capability it's not so nice
for 32-bit code to need casts to long long, so this patch makes 'L' a
modifier for bfd_vma rather than an alias for 'll'.
I've then used the new 'L' modifier to fix selected format strings.

__MSVCRT__. Support "L" modifier for bfd_vma. Formatting.
