Alexander Monakov <amonakov at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |amonakov at gcc dot gnu.org --- Comment #13 from Alexander Monakov <amonakov at gcc dot gnu.org> --- Jakub, sorry if I misunderstood the patches from a brief glance, but what ordering guarantees are you assuming for AVX accesses? It should not be SEQ_CST. I think what Intel manual is saying is that said accessing will not tear, but reordering is the same as pre-existing x86 TSO rules (a load can finish before an earlier store is globally visible).
