I just meant the break in functionality for existing users of -march=armv8r, and the drop in performance from less R52 tuning features/scheduling and the lack of Neon. I believe this is more correct, but users in the past could still get the same results by specifying `-march=armv8r -mfpu=fpv5-sp-d16`. I'm hoping someone else can come along and have an opinion on it one way or another. https://github.com/llvm/llvm-project/pull/88287 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
