i understand your means, it like a Hardware behavior to do fp16 convert to bf16（firstly, fp16 fpext to float32, second , float32 fptrunc to bfloat16). But In some target, it supply a HW instruction to complete the process (fp16->float32->bf16) . so it just supply a intrinsic (fp16 -> bf16) https://github.com/llvm/llvm-project/pull/89051 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
