Hmm. Would it ever be beneficial to attempt the True/False optimization (using the original CCReg) even if combineCCMask doesn't find a better CCreg? https://github.com/llvm/llvm-project/pull/125970 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
