The is patch adds a new ld build-id computation mode, "xx", using
xxhash in its 128-bit mode. The patch prereqs the xxhash-devel
headers being installed, and uses the "all-inlined" model, so no
run-time or link-time library dependence exists.
The xxhash mode performs well, saving roughly 20% of total userspace
run time from an ld job over a 800MB shared library relative to sha1.
128 bits of good hash should be collision-resistant to a number of
distinct binaries that numbers in the 2**32 - 2**64 range, even if not
"crypto" level hash. Confirmations of this are in progress.
ld/configury: add --with-xxhash mode, different from gdb case
because only using it in inline mode

Some tests started passing with commit 3a83f0342e54. However,
supporting a changed ld output format is not so simple, and the change
to the loongarch_elf_hash_table macro needs further changes to the
rest of the code. It is true that some uses of
loongarch_elf_hash_table do not need to check the type of the hash
table, but others like loongarch_elf_relax_section do need to check.
bfd_relax_section is called in lang_size_sections using the input bfd,
not the output bfd. If the input bfd may be of different type to the
output, then the hash table type must be checked before accessing
elements of the hash table. This patch corrects
loongarch_elf_relax_section. I haven't checked all the uses of the
hash table throughout the loongarch backend.

Testcases like ld-elf/pr19719a.c that

on success ought to see the whole output for "string match".
Similarly, the ld-pe/ pdb*.d files shouldn't need to remove the last

The reason behind this patch was noticing that generic ELF targets
fail to remove "bar" in the recently committed ld-elf/undefweak-1
test. (Despite that, those targets pass the test due to it being too
strict when matching symbols. "bar" gets turned into a local weak
defined absolute symbol.)
swap_out_syms currently drops local section syms that are defined in
discarded sections. Extend that to also drop other symbols in
discarded sections too, even global symbols. The linker goes to quite
a lot of effort to ensure globals in discarded section take a
definition from the kept linkonce or comdat group section. So the
global sym change should only affect cases where something is quite
wrong about the set of linkonce or comdat group sections. However
that change to elf_map_symbols meant we dropped _DYNAMIC_LINK /
_DYNAMIC_LINKING for mips, a global absolute symbol given STT_SECTION
type for some reason. That problem is fixed by reverting the pr14493
change which is no longer needed due to a) BSF_SECTION_SYM_USED on
x86, and b) fixing objcopy to use copy_private_symbol_data.

Linker will resolve an undefined symbol only if it is referenced by
relocation. Unreferenced weak undefined symbols serve no purpose.
Weak undefined symbols appear in the dynamic symbol table only when they
are referenced by dynamic relocation. Mark symbols with relocation and

GCC doesn't put builtin function symbol references, which are defined in
the shared C library, in the IR symbol table. When linker rescans shared
objects and archives for newly added symbol references generated from the
IR inputs, it skips definitions of the builtin functions in shared
objects and archives.
Add first_hash to elf_link_hash_table to track unreferenced definitions
defined first in shared objects and archives. Always use them to resolve
any references.

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.

The canonical form to discard all sections not mentioned earlier in
the script is
/DISCARD/ : { *(*) }
not
/DISCARD/ : { *(.*) }
".*" happens to work with the usual section names starting with a dot,
but let's not promote something not quite right.

We should be using run_host_cmd everywhere we invoke a compiler in the
ld testsuite, if we want to use ld/ld-new just built. run_host_cmd
properly inserts $gcc_B_opt in cases where a user wants to test
binutils with a newly built compiler, ie. when $CC specifies -B itself.
Also, it is not good practice to exclude tests when non-native except
of course those tests that run a target binary. Compiling and linking
often shows up problems.
* testsuite/ld-elf/no-section-header.exp (binutils_run_test):
Use run_host_cmd to invoke $CC_FOR_TARGET. Run all tests
non-native too, except for attempting to run the binaries.
Run tests for ELF in general, not just linux.

Catch "exec $CC_FOR_TARGET" won't use the gas/ld that we just build,
and in fact run_host_cmd_yesno is a better choice for it.

instead of handwrite catch exec $CC_FOR_TARGET.

Currently, the var run_tests is defined by syntax {{}},
while in this case, variables cannot be used.
Thus $NOPIE_CFLAGS and $NOPIE_LDFLAGS are passed to cmd as names
instead of values:
gcc ... $NOPIE_CFLAGS -c .../indirect5a.c -o tmpdir/indirect5a.o
Let's use [list [list ]] syntax instead.
ld/ChangeLog:
* testsuite/ld-elf/indirect.exp(run_tests): use [list [list]]
syntax instead of {{}}.
