Yes, this fix appeared to work. It looks like there are just four
14-bit references:
ppc_ftoui.S:56: blt __fixsfsi /* return directly
from there */
ppc_ftoui.S:61: blt __fixsfsi /* return directly
form there */
ppc_dtoui.S:63: blt __fixdfsi
ppc_dtoui.S:73: blt __fixdfsi
I've sent an email to the sourceforge maintainer, but I haven't heard
anything yet. It's a great library, it greatly improves FP
performance. Anyone else been using it? Any problems?
My fix is attached.
Joshua
