janus at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW --- Comment #11 from janus at gcc dot gnu.org --- (In reply to H.J. Lu from comment #10) > Does it fail without --with-arch=haswell if you add -march=haswell by hand? Yes, it does. Further investigation seems to indicate that the problem is related to AVX: Compiling the test case results in an ICE when adding -mavx or -march=sandybridge, but not with -msse4.2 or -march=westmere.
