Making a bfd_final_link failure noisy requires testsuite changes.
|
|
Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

the test expects a second, but useless, $d mapping symbol for
the partially merged section, and specifically disallows one
for the completely merged section. The new merging algorithm
makes it so that also the partially merged sections are conceptually
SEC_EXCLUDED, except the first merge section (e.g. as if the very
first object file already contains all strings). So that second mapping
symbol is now missing. It never was needed anyway.
So, adjust the test.

Many tests reflect a setting of ELF_MAXPAGESIZE to 64 KiB.
With ELF_MAXPAGESIZE changed to 4 KiB, layout is sometimes
different and symbols end up in other places. Avoid churn
and regexpification of old test patterns by passing the
max-page-size setting active at the time.

The warning about discarded sections in elf_link_input_bfd doesn't
belong there since the code is dealing with symbols. Multiple symbols
in a discarded section will result in multiple identical warnings
about the section. Move the warning to a new function in ldlang.c.
The patch also tidies the warning quoting of section and file names,
consistently using `%pA' and `%pB'. I'm no stickler for one style of
section and file name quoting, but they ought to be consistent within
a warning, eg. see the first one fixed in ldlang.c, and when a warning
is emitted for multiple targets they all ought to use exactly the same
format string to reduce translation work. elf64-ppc.c loses the
build_one_stub errors since we won't get there before hitting the
fatal errors in size_one_stub.

The discard of symbols should be performed whether the warning for
the discard is enabled or not.
Without this patch, ld would segfault in bfd_section_removed_from_list,
called in the if-statement right after this block, as the argument
isec->output_section can be NULL.

';' does not always indicate the start of a comment, and commit
8cb6e17571f3fb66ccd4fa19f881602542cd06fc incorrectly replaced 3
instances of ';' with '@' in expected diagnostics, leading to tests
failures.
This patch restores the original ';' as needed in these testcases.

Looking at the ARM disassembler output, every comment seems to start
with a ';' character, so I assumed this was the correct character to
start an assembler comment.
I then spotted a couple of places where there was no ';', but instead,
just a '@' character. I thought that this was a case of a missing
';', and proposed a patch to add the missing ';' characters.
Turns out I was wrong, '@' is actually the ARM assembler comment
character, while ';' is the statement separator. Thus this:
nop ;@ comment
is two statements, the first is the 'nop' instruction, while the
second contains no instructions, just the '@ comment' comment text.
This:
nop @ comment
is a single 'nop' instruction followed by a comment. And finally,
this:
nop ; comment
is two statements, the first contains the 'nop' instruction, while the
second contains the instruction 'comment', which obviously isn't
actually an instruction at all.
Why this matters is that, in the next commit, I would like to add
libopcodes syntax styling support for ARM.
The question then is how should the disassembler style the three cases
above?
As '@' is the actual comment start character then clearly the '@' and
anything after it can be styled as a comment. But what about ';' in
the second example? Style as text? Style as a comment?
And the third example is even harder, what about the 'comment' text?
Style as an instruction mnemonic? Style as text? Style as a comment?
I think the only sensible answer is to move the disassembler to use
'@' consistently as its comment character, and remove all the uses of
';'.
Then, in the next commit, it's obvious what to do.
There's obviously a *lot* of tests that get updated by this commit,
the only actual code changes are in opcodes/arm-dis.c.

commit 67527cffcd enabled previously disabled tests unresolved-1-dyn,
thumb-plt and thumb-plt-got for nacl. The first fails due to trying
to link against mixed-lib.so which isn't compiled for nacl. The last
two fail with

If a custom arm-elf target is disabling the shared support, a lot of
failures are reported by the testsuite.
Moreover, some tests try to access libraries which have been explicitly
skipped earlier (eg mixed-lib.so).

This changes readelf output a little, removing the 0x prefix on hex

Similar to commit 4fb55bf6a9606eb7b626c30a9f4e71d6c2d4fbb2 for aarch64.
Commit b68a20d6675f1360ea4db50a9835c073675b9889 changed ld to produce
R_ARM_GLOB_DAT but that defeated the purpose of protected visibility
as an optimization. Restore the previous behavior (which matches
ld.lld) by defining elf_backend_extern_protected_data to 0.

git commit 202be274a4 went a little wild in removing trailing spaces
in gas/testsuite/gas/i386/{secidx.d,secrel.d}, causing
x86_64-w64-mingw32 +FAIL: i386 secrel reloc
x86_64-w64-mingw32 +FAIL: i386 secidx reloc
I could have just replaced the trailing space, but let's fix the
objdump output instead. Touches lots of testsuite files.

As discussed previously, a.out support is now quite deprecated, and in
some cases removed, in both Binutils itself and NetBSD, so this legacy
default makes little sense. `netbsdelf*` and `netbsdaout*` still work
allowing the user to be explicit about there choice. Additionally, the
configure script warns about the change as Nick Clifton requested.
One possible concern was the status of NetBSD on NS32K, where only a.out
was supported. But per [1] NetBSD has removed support, and if it were to
come back, it would be with ELF. The binutils implementation is
therefore marked obsolete, per the instructions in the last message.
With that patch and this one applied, I have confirmed the following:
--target=i686-unknown-netbsd
--target=i686-unknown-netbsdelf
builds completely
--target=i686-unknown-netbsdaout
properly fails because target is deprecated.
--target=vax-unknown-netbsdaout builds completely except for gas, where
the target is deprecated.

The recent change to correct the detection of thumb2 object files
resulted in a ld test for veneering starting to fail. The problem was
the test itself, which was incorrectly expecting thumb1 type far-call
veneers instead of the thumb2 flavour. We already have a dump file of
the expected form, so the fix is to change the expected output
accordingly.

The regexpr in these two files are a bit strict in that they don't account for
the slight changes in tags in certain arm targets which cause our address
offsets to change. This changes the tests to allow slight movement in
locations while still strictly checking the rest.

When reconstructing dynamic symbol table from the PT_DYNAMIC segment,
compute dynamic symbol table size from hash table. For DT_HASH, the
number of dynamic symbol table entries equals the number of chains.
For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL
indings are in hash table. Since DT_GNU_HASH/DT_MIPS_XHASH place all
symbols with STB_LOCAL binding before symbols with other bindings and
all undefined symbols defined ones in dynamic symbol table, the highest
symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol
table index.
Rewrite print_dynamic_symbol to dump dynamic symbol table for --dyn-syms
and --syms --use-dynamic.

When you have a Thumb only PLT then the address in the GOT for PLT0 needs to
have the Thumb bit set since the instruction used in PLTn to get there is
`ldr.w pc` which is an inter-working instruction:
the PLT sequence in question is
00000120 <foo@plt>:
120: f240 0c98 movw ip, #152 ; 0x98
124: f2c0 0c01 movt ip, #1
128: 44fc add ip, pc
12a: f8dc f000 ldr.w pc, [ip]
12e: e7fc b.n 12a <foo@plt+0xa>
Disassembly of section .text:
00000130 <bar>:
130: b580 push {r7, lr}
132: af00 add r7, sp, #0
134: f7ff fff4 bl 120 <foo@plt>
and previously the linker would generate
Hex dump of section '.got':
...
0x000101b8 40010100 00000000 00000000 10010000 @...............
Which would make it jump and transition out of thumb mode and crash since you
only have thumb mode on such cores.
Now it correctly generates
Hex dump of section '.got':
...
0x000101b8 40010100 00000000 00000000 11010000 @...............

When I previously changed these offsets I had incorrectly used an offset of -2
for this Thumb2 PLT. Unfortunately because we had no tests for this PLT I had
missed that the result was incorrect.
This patch fixes the offset to PC .-4 so that it correctly addresses the
previous instruction and adds a test for this PLT stub.

We currently use a padding NOP after a Thumb to Arm interworking veneer (BX pc).
The NOP is never executed but may result in a performance penalty on some cores.

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

Similar to the AArch64 patches the Arm disassembler has the same issues with
out of order sections but also a few short comings.
For one thing there are multiple code blocks to determine mapping symbols, and
they all work slightly different, and neither fully correct. The first thing
this patch does is centralise the mapping symbols search into one function
mapping_symbol_for_insn. This function is then updated to perform a search in
a similar way as AArch64.
Their used to be a value has_mapping_symbols which was used to determine the
default disassembly for objects that have no mapping symbols. The problem with
the approach was that it was determining this value in the same loop that needed
it, which is why this field could take on the states -1, 0, 1 where -1 means
"don't know". However this means that until you actually find a mapping symbol
or reach the end of the disassembly glob, you don't know if you did the right
action or not, and if you didn't you can't correct it anymore.
This is why the two jump-reloc-veneers-* testcases end up disassembling some
insn as data when they shouldn't.
Out of order here refers to an object file where sections are not listed in a
monotonic increasing VMA order.
The ELF ABI for Arm [1] specifies the following for mapping symbols:
1) A text section must always have a corresponding mapping symbol at it's
start.
2) Data sections do not require any mapping symbols.
3) The range of a mapping symbol extends from the address it starts on up to
the next mapping symbol (exclusive) or section end (inclusive).
However there is no defined order between a symbol and it's corresponding
mapping symbol in the symbol table. This means that while in general we look
up for a corresponding mapping symbol, we have to make at least one check of
the symbol below the address being disassembled.
When disassembling different PCs within the same section, the search for mapping
symbol can be cached somewhat. We know that the mapping symbol corresponding to
the current PC is either the previous one used, or one at the same address as
the current PC.
However this optimization and mapping symbol search must stop as soon as we
reach the end or start of the section. Furthermore if we're only disassembling
a part of a section, the search is a allowed to search further than the current
chunk, but is not allowed to search past it (The mapping symbol if there, must
be at the same address, so in practice we usually stop at PC+4).
lastly, since only data sections don't require a mapping symbol the default
mapping type should be DATA and not INSN as previously defined, however if the
binary has had all its symbols stripped than this isn't very useful. To fix
this we determine the default based on the section flags. This will allow the
disassembler to be more useful on stripped binaries. If there is no section
than we assume you to be disassembling INSN.
