Yes, a user should not try to write source code(using compiler builtins) to just emit one "powerful" instruction. Instead, it is compiler's responsibility to generate these instructions according to user's source codes. I think the reason why these builtins were added is LLVM PowerPC target wants to keep its compatibility with XLC/C++ commercial compiler related to these builtins. https://github.com/llvm/llvm-project/pull/82968 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
