There was TARGET_CPU_ultrasparc3 missing in linux64.h. I've commited the following fix to the trunk, but as it is not a regression, I'm not sure if Mark is ok with this for gcc-3_4-branch. 2004-05-01 Jakub Jelinek * config/sparc/linux64.h (TARGET_DEFAULT): Make 64-bit by default also for TARGET_CPU_DEFAULT == TARGET_CPU_ultrasparc3. --- gcc-3.4.0/gcc/config/sparc/linux64.h.jj 2004-05-01 22:59:52.000000000 +0200 +++ gcc-3.4.0/gcc/config/sparc/linux64.h 2004-05-01 23:00:41.126176529 +0200 @@ -39,7 +39,9 @@ Boston, MA 02111-1307, USA. */ #undef MD_EXEC_PREFIX #undef MD_STARTFILE_PREFIX -#if TARGET_CPU_DEFAULT == TARGET_CPU_v9 || TARGET_CPU_DEFAULT == TARGET_CPU_ultrasparc +#if TARGET_CPU_DEFAULT == TARGET_CPU_v9 \ + || TARGET_CPU_DEFAULT == TARGET_CPU_ultrasparc \ + || TARGET_CPU_DEFAULT == TARGET_CPU_ultrasparc3 /* A 64 bit v9 compiler with stack-bias, in a Medium/Low code model environment. */ Jakub
