In binary output format, loongarch_elf_hash_table return NULL and result
in segment fault.
When ld output binary file, it seems that elf related functions should
not be called. But loongarch_elf_relax_section be called and
loongarch_elf_hash_table cause segment fault.
Just redefined loongarch_elf_hash_table and always return
link_info->hash.
The tests of binutils, glibc and gcc is ok.

generating two read-only segments.

If set the address of section or segment, the offset from pc to symbol
may become bigger and cause overflow.

This largely mechanical patch is preparation for a followup patch.
For quite some time I've thought that it would be useful to call
elf_backend_size_dynamic_sections even when no dynamic objects are
seen by the linker. That's what this patch does, with some renaming.
There are no functional changes to the linker, just a move of the
dynobj test in bfd_elf_size_dynamic_sections to target backend
functions, replacing the asserts/aborts already there. No doubt some
of the current always_size_sections functions could be moved to
size_dynamic_sections but I haven't made that change.
Because both hooks are now always called, I have renamed
always_size_sections to early_size_sections and size_dynamic_sections
to late_size_sections. I condisdered calling late_size_sections plain
size_sections, since this is the usual target dynamic section sizing
hook, but decided that searching the sources for "size_sections" would
then hit early_size_sections and other functions.

There are 2 problems with --fatal-warnings for unknown command-line
options:
1. --fatal-warnings doesn't trigger an error for an unknown command-line
option when --fatal-warnings is the last command-line option.
2. When --fatal-warnings triggers an error for an unknown command-line
option, the message says that the unknown command-line option is ignored.
This patch queues unknown command-line option warnings and outputs queued
command-line option warnings after all command-line options have been
processed so that --fatal-warnings can work for unknown command-line
options regardless of the order of --fatal-warnings.
When --fatal-warnings is used, the linker message is changed from
ld: warning: -z bad-option ignored
to
ld: error: unsupported option: -z bad-option
The above also applies to "-z dynamic-undefined-weak" when the known
"-z dynamic-undefined-weak" option is ignored.

For each command line option, parse_args() calls ldemul_parse_args()
to check if the command line option is an emulation option. But when
there is a conflict between the emulation option value and the default
option value, the default command line option will be processed as if
the emulation option is used. Remove PARSE_AND_LIST_PROLOGUE and move
all emulation options to ldlex.h to avoid conflicts.

RISC-V: Clarify the behaviors of SET/ADD/SUB relocations
* Bugzilla,
https://sourceware.org/bugzilla/show_bug.cgi?id=31179#c5
The addend of SUB_ULEB128 should be zero if using .uleb128, but we make it
non-zero by accident in assembler before. This causes troubles by applying
the above commit, since the calculation is changed to support .reloc *SUB*
relocations with non-zero addend.
We encourage people to rebuild their stuff to get the non-zero addend of
SUB_ULEB128, but that might need some times, so report warnings to inform
people need to rebuild their stuff if --check-uleb128 is enabled.
Since the failed .reloc cases for ADD/SET/SUB/ULEB128 are rarely to use,
it may acceptable that stop supproting them until people rebuld their stuff,
maybe half-year or a year later. Or maybe we should teach people that don't
write the .reloc R_RISCV_SUB* with non-zero constant, and then report
warnings/errors in assembler.
bfd/
* elfnn-riscv.c (perform_relocation): Ignore the non-zero addend of
R_RISCV_SUB_ULEB128.
(riscv_elf_relocate_section): Report warnings to inform people need
to rebuild their stuff if --check-uleb128 is enabled. So that can
get the right non-zero addend of R_RISCV_SUB_ULEB128.
* elfxx-riscv.h (struct riscv_elf_params): Added bool check_uleb128.
ld/
* NEWS: Updated.
* emultempl/riscvelf.em: Added linker risc-v target options,
--[no-]check-uleb128, to enable/disable checking if the addend of
uleb128 is non-zero or not. So that people will know they need to
rebuild the objects with binutils 2.42 and up, to get the right zero
addend of SUB_ULEB128 relocation, or they may get troubles if using
.reloc.

* ld/testsuite/ld-riscv-elf/pr31179*: New test cases.

The first pass handles R_LARCH_RELAX relocations, the second pass
handles R_LARCH_ALIGN relocations.
|
|
Previously the condition prevented shared objects from being relaxed.
To remove the limitation, we need to update program header size and
.eh_frame_hdr size before relaxation.

Up to now, the linker would always create a QNX stack note from scratch.
However, object files could already have such note, ending up into
duplicates. QNX loader doesn't handle that.
Update the mechanism to first search through the input files for a .note
section holding a QNX stack note. If none are found, then a new section
is created into the stub file as before. This requires this search to be
done once the file have been opened, moving the whole logic a bit later
in the emulation process.
As part for this update, also allow to request an executable stack
without necessarily having to provide its size as well. In this case, s
etup a default lazy stack of 0x1000.

Make a reference to _pei386_runtime_relocator before LTO recompilation.
This is done regardless of whether such a reference will be used,
because it can't be known whether it is needed before LTO.
I also found it necessary to enable long section names for the bfd
created in make_runtime_pseudo_reloc, because otherwise when writing
it out to the bfd-in-memory we get the section written as .rdata_r
which when read back in leads to a linker warning ".rdata_r: section
below image base" and likely runtime misbehaviour.

QNX is handling the stack argument using a .note section. Generate it
according to ELF argument -zexecstack, -zstack-size and a new NTO
argument --lazy-stack. Another NTO argument --stack mimicking
-zstack-size is added in order to ensure compatibility with previously
made NTO linkers.
This requires a new emultempl nto.em which is applied above the default
${ARCH}elf.em.

--relax enables all relaxations. --no-relax-gp disables GP relaxation to
allow measuring its effect.
The option can test effectiveness of GP relaxation and support some ABI

Commit 43025f01a0c9 ("RISC-V: Improve link time complexity.") reduced the
time complexity of the linker relaxation but some code portions did not
reflect this change.
This commit fixes a comment describing each relaxation pass and reduces
actual number of passes for the RISC-V linker relaxation from 3 to 2.
Though it does not change the functionality, it marginally improves the
performance while linking large programs (with many relocations).

* elfnn-riscv.c (_bfd_riscv_relax_section): Fix a comment to
reflect current roles of each relaxation pass.
ld/ChangeLog:
* emultempl/riscvelf.em: Reduce the number of linker relaxation
passes from 3 to 2.

This is similar to "Call bfd_close_all_done in output_file_close",
but with some code tidying in the pe/pep write_build_id functions.
write_build_id is passed the output bfd as its parameter, so there is
no need to go looking for the output bfd via link_info (and doing so
will no longer work since I clear link_info.output_bfd before calling
bfd_close).
* emultempl/pe.em (write_build_id): Rename t to td. Formatting.
Don't access pe_data(link_info.output_bfd), use td instead.
(setup_build_id): Rename t to td. Formatting.

* ldmain.c (ld_cleanup): Call bfd_close_all_done on linker bfds.

This extends PDB support to the aarch64 PE targets.
The changes to the test files are just to make it so they can be assembled as
either x86, x86_64, or aarch64, mainly by changing the comment style.
The only actual code change here is in adding the architecture constants
to pdb.c.

This fixes the test failures introduced by 87a5cf5c, by changing the
default subsystem for arm-pe from 9 (IMAGE_SUBSYSTEM_WINDOWS_CE_GUI) to
2 (IMAGE_SUBSYSTEM_WINDOWS_GUI), which matches what happens with other
PE targets.
As far as I can tell there's no working modern Windows CE toolchain
knocking about anyway, so this change shouldn't inconvenience anyone.

We already use C99's __func__ in places, use it more generally. This

remaining uses bothers anyone I invite patches.

This adds a mingw target for aarch64, including windres and dlltool.
Note that the old value of jmp_aarch64_bytes was wrong, and this does
the same thing as MSVC does.

Older bash looks to improperly deal with backslashes in here-documents,
leaving them in place on the escaped double quotes inside the parameter
expansion. Convert to a model without using such a construct, by simply
splitting the here-documents into three ones.

Enable compilation of ld/pdb.c just for x86, as is done for bfd/pdb.c.
This reduces the size of ld and is necessary with the following
patches that call a COFF-only bfd function from ld/pdb.c. Without it
we'd break every non-COFF target build.

1) The first write in write_build_id wrote rubbish past the struct
external_IMAGE_DEBUG_DIRECTORY, which was later overwritten with
correct data. No user visible problem there, except that tools like
valgrind complain.
