2024-09-24ld: support --build-id=xx modeFrank Ch. Eigler2-39/+74
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 ld/ldbuildid.c: add "xx" mode, #if WITH_XXHASH ld/NEWS, ld.texi: mention new option ld/lexsup.c: add enumeration of --build-id STYLES to --help ld/testsuite/ld-elf/build-id.exp: add test case for 0xHEX case and conditional for xx case; also, simply tcl list syntax https://inbox.sourceware.org/binutils/20240917201509.GB26396@redhat.com/ Signed-off-by: Frank Ch.

2024-08-07loongarch ld testsuite xpassesAlan Modra1-1/+1
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. bfd/ * elfnn-loongarch.c (loongarch_elf_relax_section): Don't relax unless the hash table is loongarch_elf_link_hash_table.

2024-07-22Don't trim trailing newline in run_host_cmdAlan Modra1-1/+1

2024-04-23ignore some symbols in elf.c:swap_out_symsAlan Modra1-1/+1
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. bfd/ PR 14493 * elf.c (ignore_sym): Rename from ignore_section_sym. Return true for any symbol without a section or in a discarded section. Revert pr14493 change. (elf_map_symbols): Tidy. Use ignore_sym on all symbols.

2024-01-25ld: Improve --fatal-warnings for unknown command-line optionsH.J. Lu8-0/+48
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.

2023-07-06Use run_host_cmd to run $CC and other no-section-header test fixesAlan Modra7-54/+54
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. * testsuite/ld-elf/pr25617-1-no-sec-hdr.rd: Allow localentry symbol decoration, and support either sorting of symbols. * testsuite/ld-elf/pr25617-1a-no-sec-hdr.rd: Likewise. * testsuite/ld-elf/pr25617-1a-sec-hdr.rd: Likewise. * testsuite/ld-elf/pr25617-1a-no-sec-hdr.nd: Accept D function syms. * testsuite/ld-elf/start-shared-noheader-sysv.rd: Accept mips-sgi-irix symbol output. * testsuite/ld-elf/start-shared-noheader.nd: Likewise.
2023-07-06ld: Use run_host_cmd_yesno in indirect.exp instead of catch execYunQiang Su1-4/+1
