From c6e90b027b91f0b15fd90bcacfd602eca768e4d7 Mon Sep 17 00:00:00 2001 From: Thiemo Seufer Date: Thu, 4 Apr 2002 07:01:27 +0000 Subject: [PATCH] * Makefile.am: Add elfxx-mips.c to the known backends. (elf32-mips.lo): remove dependency to coff/external.h. * Makefile.in: Regenerate. * configure.in: Add elfxx-mips.lo to all vectors using elf32-mips.lo Remove elf32-mips.lo from 64 bit vectors. Update dependencies accordingly. * configure: Regenerate. * elf-bfd.h: Move all MIPS ELF specific prototypes to elfxx-mips.h. (irix_compat_t): IRIX compatibility level, moved from elf32-mips.c. (elf_backend_mips_irix_compat, elf_backend_mips_rtype_to_howto): New MIPS specific backend functions. * elf32-mips.c: Moved most code to elfxx-mips.c. (mips_elf_hi16_reloc): Rename from _bfd_mips_elf_hi16_reloc and make static. (mips_elf_lo16_reloc): Likewise, was _bfd_mips_elf_lo16_reloc. (mips_elf_got16_reloc): Likewise, was _bfd_mips_elf_got16_reloc. (mips_elf_gprel32_reloc): Likewise, was _bfd_mips_elf_gprel32_reloc. (mips_elf32_rtype_to_howto): Rename from mips_rtype_to_howto. Changed interface to allow selection of the right REL or RELA howto table. (mips_elf32_object_p): Rename from _bfd_mips_elf_object_p and made static. Let it refuse n32 objects. (elf32_mips_grok_prstatus): Rename from _bfd_elf32_mips_grok_prstatus. (elf32_mips_grok_psinfo): Rename from _bfd_elf32_mips_grok_psinfo. (elf32_mips_discard_info): Rename from _bfd_elf32_mips_discard_info. (elf32_mips_ignore_discarded_relocs): Rename from _bfd_elf32_mips_ignore_discarded_relocs. (elf32_mips_write_section): Rename from _bfd_elf32_mips_write_section. (elf32_mips_irix_compat): New function, replaces IRIX_COMPAT. (elf_mips_howto_table_rela): Remove. * elf64-mips.c: Moved most code to elfxx-mips.c. (bfd_elf64_bfd_reloc_type_lookup): Make static. (mips_elf64_rtype_to_howto): New function. (mips_elf64_object_p): Likewise. (elf64_mips_irix_compat): Likewise. * elfxx-mips.c: New file containing common code merged together from elf32-mips.c and elf64-mips.c. * elfxx-mips.h: New file containing MIPS specific prototypes from elf-bfd.h. * elfxx-target.h: Add handling for elf_backend_mips_irix_compat and elf_backend_mips_rtype_to_howto. --- bfd/ChangeLog | 43 + bfd/Makefile.am | 16 +- bfd/Makefile.in | 539 +-- bfd/configure | 352 +- bfd/configure.in | 16 +- bfd/doc/Makefile.in | 86 +- bfd/elf-bfd.h | 95 +- bfd/elf32-mips.c | 9899 ++++--------------------------------------- bfd/elf64-mips.c | 4688 +------------------- bfd/elfxx-target.h | 8 + 10 files changed, 1382 insertions(+), 14360 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 6680bdb570a..961a6dddb04 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,46 @@ +2002-04-04 Thiemo Seufer + + * Makefile.am: Add elfxx-mips.c to the known backends. + (elf32-mips.lo): remove dependency to coff/external.h. + * Makefile.in: Regenerate. + * configure.in: Add elfxx-mips.lo to all vectors using elf32-mips.lo + Remove elf32-mips.lo from 64 bit vectors.
