[ bfd/ChangeLog ]
2004-04-23 Chris Demetriou <cgd@broadcom.com>
* coff-mips.c (mips_relhi_reloc, mips_rello_reloc)
(mips_switch_reloc, mips_read_relocs, mips_relax_section)
(mips_relax_pcrel16, PCREL16_EXPANSION_ADJUSTMENT): Remove.
(mips_relocate_hi): Remove now-unused 'adjust' and 'pcrel' arguments,
and update comments to reflect current usage.
(mips_howto_table): Remove entries for MIPS_R_RELHI, MIPS_R_RELLO,
and MIPS_R_SWITCH, as well as several empty entries. Update comment
for MIPS_R_PCREL16.
(mips_ecoff_swap_reloc_in, mips_ecoff_swap_reloc_out)
(mips_adjust_reloc_out, mips_bfd_reloc_type_lookup): Remove support
for MIPS_R_SWITCH, MIPS_R_RELLO, and MIPS_R_RELHI relocations.
(mips_adjust_reloc_in): Likewise, adjust maximum accepted relocation
type number to be MIPS_R_PCREL16.
(mips_relocate_section): Remove support for link-time relaxation
of branches used by embedded-PIC. Remove support for MIPS_R_SWITCH,
MIPS_R_RELLO, and MIPS_R_RELHI relocations.
(_bfd_ecoff_bfd_relax_section): Redefine to bfd_generic_relax_section.
* ecoff.c (ecoff_indirect_link_order): Remove support for link-time
relaxation of branches used by embedded-PIC.
* ecofflink.c (bfd_ecoff_debug_accumulate): Likewise.
* libecoff.h (struct ecoff_section_tdata): Remove embedded-PIC
related members, update comment.
* pe-mips.c: Remove disabled (commented-out and #if 0'd)
code related to embedded-PIC.
* elfxx-mips.c (_bfd_mips_elf_read_ecoff_info): Remove
initialization of now-removed 'adjust' member of
'struct ecoff_debug_info'.
