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.

* config/sparc/linux64.h (TARGET_DEFAULT): Make 64-bit by default
|

also for TARGET_CPU_DEFAULT == TARGET_CPU_ultrasparc3.
