Re: [PATCH #1] mips*-kfreebsd-gnu support in BFD
- From: Robert Millan <rmh at gnu dot org>
- To: binutils at sourceware dot org

- Subject: Re: [PATCH #1] mips*-kfreebsd-gnu support in BFD
- References: <1292259049.699.0@thorin>
Please consider this new version which also includes support
for FreeBSD.
2010-12-14 Robert Millan <rmh@gnu.org>
* bfd/config.bfd: Recognize mips-freebsd and mips-kfreebsd-gnu.
* bfd/configure.host: Likewise.
* bfd/configure.in: Support for `bfd_elf32_ntradbigmips_freebsd_vec',
`bfd_elf32_ntradlittlemips_freebsd_vec',
`bfd_elf32_tradbigmips_freebsd_vec',
`bfd_elf32_tradlittlemips_freebsd_vec',
`bfd_elf64_tradbigmips_freebsd_vec' and
`bfd_elf64_tradlittlemips_freebsd_vec'.
* bfd/configure: Regenerate.
* bfd/elf32-mips.c: New target for FreeBSD support
(same as traditional MIPS but overrides ELF_OSABI
with ELFOSABI_FREEBSD).
* bfd/elf64-mips.c: Likewise.
* bfd/elfn32-mips.c: Likewise.
* bfd/targets.c (_bfd_target_vector): Add
`bfd_elf32_ntradbigmips_freebsd_vec',
`bfd_elf32_ntradlittlemips_freebsd_vec',
`bfd_elf32_tradbigmips_freebsd_vec',
`bfd_elf32_tradlittlemips_freebsd_vec',
`bfd_elf64_tradbigmips_freebsd_vec' and
`bfd_elf64_tradlittlemips_freebsd_vec'.
