sdardis marked 3 inline comments as done. sdardis added a comment. Thanks for getting back to this. I've traced the appearance of the ext_vector type to a piece of code that only produces ext-vector types for comparisons. I'm presuming that's wrong when clang is producing vectors implicitly in the non-OpenCL case. I'll update the diff once I've changed that.

Sema::CheckVectorCompareOperands calls Sema::GetSignedVectorType which only returns ext-vector types. I presume that is now incorrect if we're producing vectors from literal scalars in the non OpenCL case. https://reviews.llvm.org/D25866 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
