+
+ * 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.
