sdardis added a comment. Checking the generated IR for the incorrect uses of v8f16 shows that clang is silently generating bitcasts from <8 x i16> to <4 x float>. There are some other cases where the type of the operands is incorrect w.r.t. the builtin used.
I'm not familiar with the type checking machinery, so I'm unsure if the silent conversion is a bug or feature. https://reviews.llvm.org/D24674 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
