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.
