Setting the flags overwrites the CPU_SPEC that's normally set to __sparc64__. >How-To-Repeat: Add -mcpu=ultrasparc to you CFLAGS= configuration in /etc/make.conf, then try to compile world or any kernel. >Fix: Apply the attached patch which adds the following to /usr/src/contrib/gcc/config/sparc/freebsd.h: builtin_define ("__sparc64__"); builtin_define ("__sparc_v9__"); builtin_define ("__sparcv9"); builtin_define ("__arch64__"); Patch attached with submission follows: *** contrib/gcc/config/sparc/freebsd.h Tue Jul 27 22:00:13 2004 --- contrib/gcc/config/sparc/temp/freebsd.h Sat Feb 24 16:56:33 2007 *************** *** 34,44 **** #undef FBSD_TARGET_CPU_CPP_BUILTINS #define FBSD_TARGET_CPU_CPP_BUILTINS() \ do \ { \ builtin_define ("__LP64__"); \ ! } \ while (0) #define LINK_SPEC "%(link_arch) \ %{!mno-relax:%{!r:-relax}} \ %{p:%nconsider using `-pg' instead of `-p' with gprof(1)} \ --- 34,48 ---- #undef FBSD_TARGET_CPU_CPP_BUILTINS #define FBSD_TARGET_CPU_CPP_BUILTINS() \ do \ { \ builtin_define ("__LP64__"); \ ! builtin_define ("__sparc64__"); \ ! builtin_define ("__sparc_v9__"); \ ! builtin_define ("__sparcv9"); \ ! builtin_define ("__arch64__"); \ ! } \ while (0) #define LINK_SPEC "%(link_arch) \ %{!mno-relax:%{!r:-relax}} \ %{p:%nconsider using `-pg' instead of `-p' with gprof(1)} \ >Release-Note: >Audit-Trail: >Unformatted:
