Sure, it makes the chip "v8.5 (excluding FEAT_BTI)", which is what's written in the guide ;) The guide is intended as a human-readable guide for high-performance software writers, not as much as the almost-only-machine-readable specifications we're used to reading. The alternative would have been "v8.4a + all these features from v8.5" which is worse. https://github.com/llvm/llvm-project/pull/92600 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
