Steve Ellcey <sje at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sje at gcc dot gnu.org --- Comment #5 from Steve Ellcey <sje at gcc dot gnu.org> --- Has anyone looked into this any more to see what optimization is causing this failure? In my testing: -Ofast fails -Ofast -fno-unsafe-math-optimizations works -Ofast -fno-tree-loop-vectorize works -O3 works So it seems to be some combination of unsafe math optimizations and vectorization that is causing the failure.
