PR ld/22972 on SPARC. This is a regression for the corner case of a hidden symbol in a PIC/PIE binary which is subject to both a new-style GOTDATA relocation and an old-style GOT relocation. In this case, depending on the link order, the R_SPARC_RELATIVE dynamic relocation for the GOT slot needed because of the old-style relocation can be replaced with R_SPARC_NONE coming from the GOTDATA relocation. The fix simply records whether an old-style GOT relocation is seen for a symbol and prevents the R_SPARC_NONE from being generated in this case. bfd/ * elfxx-sparc.c (struct _bfd_sparc_elf_link_hash_entry): Add new flag has_old_style_got_reloc. (_bfd_sparc_elf_check_relocs) <GOT relocations>: Set it for old-style relocations. Fix a couple of long lines. (_bfd_sparc_elf_relocate_section) <R_SPARC_GOTDATA_OP>: Do not generate a R_SPARC_NONE for the GOT slot if the symbol is also subject to old-style GOT relocations. ld/ * testsuite/ld-sparc/sparc.exp: Add test for mixed GOTDATA/GOT relocs. * testsuite/ld-sparc/gotop-hidden.c: New file. * testsuite/ld-sparc/got-hidden32.s: Likewise. * testsuite/ld-sparc/got-hidden64.s: Likewise. * testsuite/ld-sparc/pass.out: Likewise. 2018-03-28 18:17:15 +08:00			`.text`
