Given @efriedma-quic 's comment, we should specify the targets here. Maybe change the first sentence to "On certain targets (ARM, PowerPC, VE, X86), ..." and the second sentence to "On other targets (SystemZ), ..." https://github.com/llvm/llvm-project/pull/116642 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
