--- Comment #12 from Wilco <wilco at gcc dot gnu.org> --- (In reply to Richard Biener from comment #9) > I have also always wondered about that glibc guard, esp. it being the > kitchen-sink fast-math guard rather than sth more specific (yep, we don't > have anything for -funsafe-math-optimizations). That is, I suppose glibc > does not set > FP exception flags "correctly" either. > > Is there documentation on what you can expect from the glibc vector math > functions with regard to IEEE conformance? https://sourceware.org/glibc/wiki/libmvec is generally applicable and lists why vector math libraries are essentially fast-math only.
