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'. [ include/coff/ChangeLog ] 2004-04-23 Chris Demetriou <cgd@broadcom.com> * mips.h (MIPS_R_RELHI, MIPS_R_RELLO, MIPS_R_SWITCH): Remove (MIPS_R_PCREL16): Update comment. * ecoff.h (struct ecoff_value_adjust): Remove structure. (struct ecoff_debug_info): Remove 'adjust' member.

- The object file will contain the correct difference, and does not
