2022-05-06bfd targmatch.h makefile ruleAlan Modra2-2/+2
I hit this just now with a make -j build after touching config.bfd. mv: cannot stat 'targmatch.new': No such file or directory make[2]: *** [Makefile:2336: targmatch.h] Error 1 make[2]: *** Waiting for unfinished jobs.... Fix that by not removing the target of the rule, a practice that seems likely to cause parallel running of the rule recipe. The bug goes back to 1997, the initial c0734708814c commit. * Makefile.am (targmatch.h): rm the temp file, not targmatch.h. * Makefile.in: Regenerate.

2022-05-05loongarch: Don't check ABI flags if no code sectionXi Ruoyao1-0/+21
Various packages (glib and gtk4 for example) produces data-only objects using `ld -r -b binary` or `objcopy`, with no elf header flags set. But these files also have no code sections, so they should be compatible with all ABIs. bfd/ * elfnn-loongarch.c (elfNN_loongarch_merge_private_bfd_data): Skip ABI checks if the input has no code sections.

2022-05-04LTO: Handle __real_SYM reference in IRH.J. Lu1-0/+1
When an IR symbol SYM is referenced in IR via __real_SYM, its resolution should be LDPR_PREVAILING_DEF, not PREVAILING_DEF_IRONLY, since LTO doesn't know that __real_SYM should be resolved by SYM. bfd/ PR ld/29086 * linker.c (bfd_wrapped_link_hash_lookup): Mark SYM is referenced via __real_SYM. include/ PR ld/29086 * bfdlink.h (bfd_link_hash_entry): Add ref_real. ld/ PR ld/29086 * plugin.c (get_symbols): Resolve SYM definition to LDPR_PREVAILING_DEF for __real_SYM reference. * testsuite/ld-plugin/lto.exp: Run PR ld/29086 test. * testsuite/ld-plugin/pr29086.c: New file.

2022-04-28s390: Add DT_JMPREL pointing to .rela.[i]plt with static-pieStefan Liebler1-1/+14
In static-pie case, there are IRELATIVE-relocs in .rela.iplt (htab->irelplt), which will later be grouped to .rela.plt. On s390, the IRELATIVE relocations are always located in .rela.iplt - even for non-static case. Ensure that DT_JMPREL, DT_PLTRELA, DT_PLTRELASZ is added to the dynamic section even if htab->srelplt->size == 0. See _bfd_elf_add_dynamic_tags in bfd/elflink.c. bfd/ elf64-s390.c (elf_s390_size_dynamic_sections): Enforce DT_JMPREL via htab->elf.dt_jmprel_required.
