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> --- Looking at the code and the aarch64 documentation, the non-vectorized version does the comparisons with fcmp which is defined as a "quiet compare" and only generates an exception for signaling NANs. The vectorized version uses fcmgt and that is defined to raise exceptions. I am not sure what GCC can do here other than manually clear the exceptions that fcmgt raised (Yuk).
