Despite the documentation, this doesn't seem to work in DXC for arbitrary types: https://godbolt.org/z/48brf1bre @tex3d, gen_intrin_main says this intrinsic is valid on `any<>`, which seems to be any vector or scalar. Is that correct? https://github.com/llvm/llvm-project/pull/111010 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
