(microblaze_elf_relocate_section): Accommodate TLS relocations. (microblaze_elf_check_relocs): Likewise (update_local_sym_info): New (microblaze_elf_copy_indirect_symbol): Add tls_mask. (allocate_dynrelocs): Handle TLS symbol (microblaze_elf_size_dynamic_sections): Set size and offset (microblaze_elf_finish_dynamic_symbol): Use microblaze_elf_output_dynamic_relocation gas/Changelog * config/tc-microblaze.c: Define TLS offsets (md_relax_table): Add TLS offsets (imm_types), (match_imm), (get_imm_otype): New to support TLS offsets. (tc_microblaze_fix_adjustable): Add TLS relocs. (md_convert_frag): Support TLS offsets. (md_apply_fix), (md_estimate_size_before_relax), (tc_gen_reloc): Add TLS relocs include/Changelog * elf/microblaze.h: Add TLS relocs to START_RELOC_NUMBERS --- include/ChangeLog | 4 ++++ include/elf/microblaze.h | 8 ++++++++ 2 files changed, 12 insertions(+) diff --git a/include/ChangeLog b/include/ChangeLog index 571fe7481..16ff7e64d 100644 --- a/include/ChangeLog +++ b/include/ChangeLog @@ -1,3 +1,7 @@ +2012-12-11 Edgar E.
