[PATCH] add FreeBSD-specific `ld' emulations
- From: "David O'Brien" <obrien at FreeBSD dot org>
- To: GNU Binutils mailing list <binutils at sources dot redhat dot com>
- Date: Sun, 17 Feb 2002 21:34:44 -0800
- Subject: [PATCH] add FreeBSD-specific `ld' emulations
- Organization: The NUXI BSD group
- Reply-to: obrien at FreeBSD dot org
2002-02-17 David O'Brien <obrien@FreeBSD.org>
* Makefile.in: Add new files earmelf_fbsd, eelf32ppc_fbsd,
eelf_i386_fbsd, eelf64_ia64_fbsd, eelf_x86_64_fbsd, eelf64_sparc_fbsd,
and eelf64alpha_fbsd.
* configure.tgt(sparc64-*-freebsd, ia64-*-freebsd, i[3456]86-*-freebsd,
x86_64-*-freebsd, arm-*-freebsd, alpha*-*-freebsd, powerpc-*-freebsd):
use a FreeBSD-specific emulation rather than the psABI one.
* emulparams/elf_fbsd.sh (ELF_INTERPRETER_NAME): Set appropriate value
for all FreeBSD ELF systems.
* emulparams/armelf_fbsd.sh: Bridge elf_fbsd.sh and the "native" psABI
emulation.
* emulparams/elf32ppc_fbsd.sh: Likewise.
* emulparams/elf64_ia64_fbsd.sh: Likewise.
* emulparams/elf64_sparc_fbsd.sh: Likewise.
* emulparams/elf64alpha_fbsd.sh: Likewise.
* emulparams/elf_i386_fbsd.sh: Likewise.
* emulparams/elf_x86_64_fbsd.sh: Likewise.
* emulparams/i386freebsd.sh: Likewise.
