From 71a75f6f15bcaf99d98bb50ddd57ec8e8d1bbc9d Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 18 Oct 2006 23:58:52 +0000 Subject: 2006-10-18 Roy Marples * bfd/elf64-sparc.c: Add FreeBSD support. (elf64_sparc_fbsd_post_process_headers): New function. * bfd/targets.c (_bfd_target_vector): Add bfd_elf64_sparc_freebsd_vec. * bfd/config.bfd (sparc64-*-freebsd*): Set targ_defvec to bfd_elf64_sparc_freebsd_vec. * bfd/configure.in: Add entry for bfd_elf64_sparc_freebsd_vec. * bfd/configure: Regenerate. * gas/config/tc-sparc.c (md_parse_option): Treat any target starting with elf32-sparc as a viable target for the -32 switch and any target starting with elf64-sparc as a viable target for the -64 switch. (sparc_target_format): For 64-bit ELF flavoured output use ELF_TARGET_FORMAT64 while for 32-bit ELF flavoured output use ELF_TARGET_FORMAT. * gas/config/tc-sparc.h (ELF_TARGET_FORMAT, ELF_TARGET_FORMAT64): Define. * ld/emulparams/elf64_sparc_fbsd.sh (OUTPUT_FORMAT): Define as elf64-sparc-freebsd. --- bfd/elf64-sparc.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) (limited to 'bfd/elf64-sparc.c') diff --git a/bfd/elf64-sparc.c b/bfd/elf64-sparc.c index 1185553..0eefc95 100644 --- a/bfd/elf64-sparc.c +++ b/bfd/elf64-sparc.c @@ -904,3 +904,33 @@ const struct elf_size_info elf64_sparc_size_info = #define elf_backend_plt_alignment 8 #include "elf64-target.h" + +/* FreeBSD support */ +#undef TARGET_BIG_SYM +#define TARGET_BIG_SYM bfd_elf64_sparc_freebsd_vec +#undef TARGET_BIG_NAME +#define TARGET_BIG_NAME "elf64-sparc-freebsd" + +/* The kernel recognizes executables as valid only if they carry a + "FreeBSD" label in the ELF header.
