I've created http://reviews.llvm.org/D21272 that covers the conversion of SSE/SSE2/AVX/AVX512 non-temporal aligned vector stores to use __builtin_nontemporal_store in headers http://reviews.llvm.org/D20358 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
