--- Comment #7 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-06-07 13:47:00 UTC --- The original failure only occured with -O0 compile and -O2 -ffast-math link. The linker-plugin use was already a workaround for the -O0 link by collect2, so not sure why that isn't working anymore. Thus, I guess this still needs investigation. I don't see the cabs -> sqrt (pow, pow) folding anymore. Ah, because it happens from PRE which folds and inserts cabs into the predecessor. But PRE runs after pass_sincos. I think the cabs -> sqrt (pow, pow) folding should happen during pass_sincos.
