------- Comment #4 from rguenth at gcc dot gnu dot org 2010-03-27 12:53 ------- No, sseregparm should be perfectly fine with x87 math - it only needs (obviously) SSE registers available. It's an ABI switch like regparm, whether math is done using SSE registers or x87 math doesn't and shouldn't matter.
The workaround looks odd - it can't be the real solution. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43546
