nightstrike <nightstrike at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |WORKSFORME --- Comment #4 from nightstrike <nightstrike at gmail dot com> --- (In reply to Marc Glisse from comment #3) > Intel defaults to the equivalent of -ffast-math, did you try with that? *sigh*... no, I didn't. And of course, that makes them exactly equal. In fact, for larger size (100k) to get more time resolution, they are exactly equal for either gcc with -ffast-math and intel defaults, or gcc defaults and intel with -fp-model=strict. So yes, nothing to see here. Sorry for the noise :( This is why I like to ask silly things first on IRC or the mailing list.
