This mixes type naming conventions. Probably should stick to the IR convention (and say `bfloat`, `<2 x i16>`, `<2 x half>`, `<2 x bfloat>`. Also, pointers double, and multiples of the 32-bit vectors should work. https://github.com/llvm/llvm-project/pull/89217 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
