From 0491778eb8a730a7c66aa3c893dfeafb5f400783 Mon Sep 17 00:00:00 2001 From: obrien Date: Wed, 21 Nov 2001 02:06:45 +0000 Subject: [PATCH] 2001-11-20 David O'Brien * config.gcc: Add FreeBSD/PowerPC target. (powerpc64-*-linux*, powerpc-*-sysv*, powerpc-*-netbsd*, powerpc-*-chorusos*, powerpc-*-eabiaix*, powerpc-*-eabisim*, powerpc-*-elf*, powerpc-*-eabi*, powerpc-*-rtems*, powerpc-*-linux*libc1, powerpc-*-linux*, powerpc-wrs-vxworks*, powerpcle-wrs-vxworks*, powerpcle-*-sysv*, powerpcle-*-elf*, powerpcle-*-eabisim*, powerpcle-*-eabi*, powerpcle-*-solaris2*): Add freebsd-spec.h to tm_file. (rs6000-*-lynxos*): Add lynx.h to tm_file. * config/freebsd.h: Tidy up. (USING_CONFIG_FREEBSD): Define. (FBSD_SWITCH_TAKES_ARG, FBSD_WORD_SWITCH_TAKES_ARG, FBSD_CPP_PREDEFINES, FBSD_CPP_SPEC, FBSD_STARTFILE_SPEC, FBSD_ENDFILE_SPEC, FBSD_LIB_SPEC): Remove (moved to freebsd-spec.h). (TARGET_HAS_F_SETLKW): Define. (ASM_OUTPUT_IDENT): Delete, the elfos.h definition is fine. * config/freebsd-spec.h: New file. * config/rs6000/freebsd.h: New file. * config/rs6000/rs6000.h (TARGET_VERSION): Do not define. * config/rs6000/rs6000.c: Test for USING_ELFOS_H rather than USING_SVR4_H to know when to turn on ELF support. * config/rs6000/sysv4.h (TARGET_VERSION, CPP_PREDEFINES): Don't undef, define only if not already defined. Add FreeBSD support. * config/rs6000/aix.h (TARGET_VERSION): Define. * config/rs6000/beos.h: Likewise. * config/rs6000/darwin.h: Likewise. * config/rs6000/mach.h: Likewise. * config/rs6000/lynx.h (TARGET_VERSION): Likewise. Don't include lynx.h directly.
