Alexander Monakov <amonakov at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |amonakov at gcc dot gnu.org --- Comment #2 from Alexander Monakov <amonakov at gcc dot gnu.org> --- It seems csmith was run with the --float argument. Differences under -Ofast are expected (but even without -Ofast, it seems csmith can emit bit manipulation of arbitrary floats, which can lead to unpredictable results when NaNs are involved).
