+Subject: [PATCH] Avoid infinite loop between DAGCombiner::visitMUL and
+ RISCVISelLowering::transformAddImmMulImm
+
+See https://github.com/llvm/llvm-project/issues/53831 for a full discussion.
+
+The basic issue is that DAGCombiner::visitMUL and
+RISCVISelLowering;:transformAddImmMullImm get stuck in a loop, as the
+current checks in transformAddImmMulImm aren't sufficient to avoid all
+cases where DAGCombiner::isMulAddWithConstProfitable might trigger a
+transformation. This patch makes transformAddImmMulImm bail out if C0
+(the constant used for multiplication) has more than one use.
+
+Differential Revision: https://reviews.llvm.org/D120332
+
+(cherry picked from commit c5bcfb983e47167a8a1826c1a64d7aa1849add06)
