config.gcc: Add FreeBSD/IA-64 target.
2001-11-07 David O'Brien <obrien@FreeBSD.org>
* config.gcc: Add FreeBSD/IA-64 target. Expand config/i64/elf.h headers.
* config/i64/ia64.h (TARGET_VERSION,ASM_SPEC,LINK_SPEC): Remove,
they are OS specific. Use CPP_CPU_SPEC rather than CPP_PREDEFINES,
so OS specific files and use CPP_PREDEFINES for their needs.
* config/i64/elf.h (TARGET_VERSION): Add. Also, move inclusion of
target headers to tm_file.
* config/ia64/aix.h (TARGET_VERSION): Likewise.
* config/ia64/hpux.h (TARGET_VERSION): Likewise.
* config/ia64/linux.h (TARGET_VERSION): Likewise.
(FUNCTION_PROFILER): Remove.
* config/ia64/ia64.h (FUNCTION_PROFILER): Update defintion using the
version in config/ia64/linux.h.
* config/ia64/freebsd.h: New file.
* config/freebsd.h: Tidy up.
(_USING_CONFIG_FREEBSD): Define.
(FBSD_CPP_PREDEFINES): Add __KPRINTF_ATTRIBUTE__.
(FBSD_CPP_SPEC): Define generic FreeBSD spec.
(FBSD_STARTFILE_SPEC): Likewise.
(FBSD_ENDFILE_SPEC): Likewise.
(FBSD_LIB_SPEC): Likewise.
(WCHAR_UNSIGNED): Undefine, FreeBSD's wchars are signed.
(USER_LABEL_PREFIX): Define to ELF compatible value as some CPU headers
set an ELF-improper one.
