Linker adds indirect symbols for versioned symbol aliases, which are
created by ".symver foo, foo@FOO", by checking symbol type, value and
section so that references to foo will be replaced by references to
foo@FOO if foo and foo@FOO have the same symbol type, value and section.
But in IR, since all symbols of the same type have the same value and
section, we can't tell if a symbol is an alias of another symbol by
their types, values and sections. We shouldn't add indirect symbols
for versioned symbol aliases in IR.

bfd_malloc_and_get_section does size sanity checking before allocating
memory and reading contents. These size checks are not done for bss
style sections, because they typically don't occupy file space and
thus can't be compared against file size. However, if you are
expecting to look at something other than a whole lot of zeros, don't
allow fuzzers to avoid the size checking.

* use power-of-two hash table
* use better hash function (hashing 32bits at once and with better
mixing characteristics)
* use input-offset-to-entry maps instead of retaining full input
contents for lookup time
* don't reread SEC_MERGE section multiple times
* care for cache behaviour for the hot lookup routine
The overall effect is less usage in libz and much faster string merging
itself. On a debug-info-enabled cc1 the effect at the time of this
writing on the machine I used was going from 14400 perf samples to 9300
perf samples or from 3.7 seconds to 2.4 seconds, i.e. about 33% .

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 linker merges all the input .sframe sections. When merging, the
linker verifies that all the input .sframe sections have the same
abi/arch.
The linker uses libsframe library to perform key actions on the
.sframe sections - decode, read, and create output data. This
implies buildsystem changes to make and install libsframe before
libbfd.
The linker places the output .sframe section in a new segment of its
own: PT_GNU_SFRAME. A new segment is not added, however, if the
generated .sframe section is empty.
When a section is discarded from the final link, the corresponding
entries in the .sframe section for those functions are also deleted.
The linker sorts the SFrame FDEs on start address by default and sets
the SFRAME_F_FDE_SORTED flag in the .sframe section.
This patch also adds support for generation of SFrame unwind
information for the .plt* sections on x86_64. SFrame unwind info is
generated for IBT enabled PLT, lazy/non-lazy PLT.
The existing linker option --no-ld-generated-unwind-info has been
adapted to include the control of whether .sframe unwind information
will be generated for the linker generated sections like PLT.
Changes to the linker script have been made as necessary.

The bug testcase uses an output section named .rel or .rela which has
input .data sections mapped to it. The input .data section has
relocations. When counting output relocations SHT_REL and SHT_RELA
section reloc_count is ignored, with the justification that reloc
sections themselves can't have relocations and some backends use
reloc_count in reloc sections. However, the test wrongly used the
output section type (which normally would match input section type).
Fix that. Note that it is arguably wrong for ld to leave the output
.rel/.rela section type as SHT_REL/SHT_RELA when non-empty non-reloc
sections are written to it, but I'm not going to change that since it
might be useful to hand-craft relocs in a data section that is then
written to a SHT_REL/SHT_RELA output section.

bfd_hostptr_t is defined as a type large enough to hold either a long
or a pointer. It mostly appears in the coff backend code in casts.
include/coff/internal.h struct internal_syment and union
internal_auxent have the only uses in data structures, where
comparison with include/coff/external.h and other code reveals that
the type only needs to be large enough for a 32-bit integer or a
pointer. That should mean replacing with uintptr_t is OK.
|
|
Requiring C99 means that uses of bfd_uint64_t can be replaced with
uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and
BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_*
and tidies a few places that print 64-bit values.

DT_RELR encodes consecutive R_*_RELATIVE relocations in GOT (the global
offset table) and data sections in a compact format:
https://groups.google.com/g/generic-abi/c/bX460iggiKg
On some targets, R_*_RELATIVE relocations are counted and the GOT offsets
are allocated when setting the dynamic section sizes after seeing all
relocations. R_*_RELATIVE relocations are generated while relocating
sections after section layout has been finalized.
To prepare for DT_RELR implementation on these targets, extract
_bfd_elf_link_iterate_on_relocs from _bfd_elf_link_check_relocs so
that a backend can scan relocations in elf_backend_always_size_sections
For x86 targets, the old check_relocs is renamed to scan_relocs and a
new check_relocs is added to chek input sections and create dynamic
relocation sections so that they will be mapped to output sections.
scan_relocs is now called from elf_backend_always_size_sections.
Since relocations are scanned after __start, __stop, .startof. and
.sizeof. symbols have been finalized on x86, __[start|stop]_SECNAME for
--gc-sections -z start-stop-gc are now zero when all SECNAME sections
been garbage collected. This is no need for elf_x86_start_stop_gc_p.

.symtab_shndx section contents is an array, one entry for each symbol
in .symtab, present when the number of symbols exceeds a little less
than 64k. Since the mapping is 1-1 with symbols there is no need to
keep both dest_index and destshndx_index in elf_sym_strtab. Instead,
just make sure that the shndx pointers to the swap functions are kept
NULL when .symtab_shndx does not exist. Also, strtabcount in the
linker's elf hash table is incremented in lock-step with the output
symcount, so that can disappear too.

This defines a couple of macros used to avoid ubsan complaints about
calculations involving NULL pointers. PTR_ADD should be used in the
case where it is known that the offset is always zero with a NULL
pointer, and you'd like to know if a non-zero offset is ever used.
NPTR_ADD should be rarely used, but is defined for cases where a
non-zero offset is expected and should be ignored if the pointer is
NULL.
