New Revision: 341101
URL: https://svnweb.freebsd.org/changeset/base/341101
Log:
powerpcspe: Don't crash the loader on ubldr with SPE instructions.
-msoft-float seems to be insufficient for disabling the SPE on powerpcspe.
Force it off with -mno-spe as well. This prevents a crash in ubldr on
powerpcspe.
