You can check that the loop metadata is stripped here by using a regex for the end of the line: ```suggestion %cmp.i = icmp ult i32 1, 2 ; CHECK: br i1 %cmp.i, label %exit, label %exit{{$}} br i1 %cmp.i, label %exit, label %exit, !llvm.loop !0 exit: ret void ``` https://github.com/llvm/llvm-project/pull/136386 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
