--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> --- (In reply to Kamlesh Kumar from comment #9) > $./ccppc -mcpu=e6500 -mabi=elfv2 -msoft-float -m64 test.c Maybe it is because not many people use soft-float with 64bit which explains why this has not been seen before. I don't know of a a 64bit PowerPC which does not have a FPU. The only place where soft-float is used is inside the kernel and almost nobody if any uses float in there.
