bfd/ * reloc.c (BFD_RELOC_386_TLS_TPOFF, BFD_RELOC_386_TLS_IE, BFD_RELOC_386_TLS_GOTIE): Add. * bfd-in2.h, libbfd.h: Rebuilt. * elf32-i386.c (elf_howto_table): Add R_386_TLS_TPOFF, R_386_TLS_IE and R_386_TLS_GOTIE. (elf_i386_reloc_type_lookup): Handle it. (struct elf_i386_link_hash_entry): Change tls_type type to unsigned char instead of enum, change GOT_* into defines. (GOT_TLS_IE_POS, GOT_TLS_IE_NEG, GOT_TLS_IE_BOTH): Define. (elf_i386_tls_transition): Handle R_386_TLS_IE and R_386_TLS_GOTIE. (elf_i386_check_relocs): Likewise. Avoid crash if local symbol is accessed both as normal and TLS symbol. Move R_386_TLS_LDM and R_386_PLT32 cases so that R_386_TLS_IE can fall through. Handle R_386_TLS_LE_32 and R_386_TLS_LE in shared libs. (elf_i386_gc_sweep_hook): Handle R_386_TLS_IE and R_386_TLS_GOTIE. Handle R_386_TLS_LE_32 and R_386_TLS_LE in shared libs. (allocate_dynrelocs): Allocate 2 .got and 2 .rel.got entries if tls_type is GOT_TLS_IE_BOTH. (elf_i386_size_dynamic_sections): Likewise. (elf_i386_relocate_section): Handle R_386_TLS_IE and R_386_TLS_GOTIE. Handle R_386_TLS_LE_32 and R_386_TLS_LE in shared libs. (elf_i386_finish_dynamic_symbol): Use tls_type & GOT_TLS_IE to catch all 4 GOT_TLS_* TLS types. gas/ * config/tc-i386.c (tc_i386_fix_adjustable): Handle BFD_RELOC_386_TLS_IE and BFD_RELOC_386_TLS_GOTIE. (BFD_RELOC_386_TLS_IE, BFD_RELOC_386_TLS_GOTIE): Define to 0 if not defined. (lex_got): Handle @GOTNTPOFF and @INDNTPOFF. (md_apply_fix3, tc_gen_reloc): Handle BFD_RELOC_386_TLS_IE and BFD_RELOC_386_TLS_GOTIE. gas/testsuite/ * gas/i386/tlspic.s: Add tests. * gas/i386/tlspic.d: Regenerated. * gas/i386/tlsnopic.s: Add tests. * gas/i386/tlsnopic.d: Regenerated. include/ * elf/i386.h (R_386_TLS_TPOFF, R_386_TLS_IE, R_386_TLS_GOTIE): Define. ld/testsuite/ * ld-i386/i386.exp: New. * ld-i386/tlsbin.dd: New test. * ld-i386/tlsbinpic.s: New test. * ld-i386/tlsbin.rd: New test. * ld-i386/tlsbin.s: New test. * ld-i386/tlsbin.sd: New test. * ld-i386/tlsbin.td: New test. * ld-i386/tlslib.s: New test. * ld-i386/tlsnopic1.s: New test. * ld-i386/tlsnopic2.s: New test. * ld-i386/tlsnopic.dd: New test. * ld-i386/tlsnopic.rd: New test. * ld-i386/tlsnopic.sd: New test. * ld-i386/tlspic1.s: New test. * ld-i386/tlspic2.s: New test. * ld-i386/tlspic.dd: New test. * ld-i386/tlspic.rd: New test. * ld-i386/tlspic.sd: New test. * ld-i386/tlspic.td: New test.
