[PATCH] D133695: [InstCombine] Optimize multiplication where both operands are negated

[Florian Hahn via Phabricator via llvm-commits]

fhahn added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCalls.cpp:1833
+  case Intrinsic::matrix_multiply: {
+    // Optimise -A * -B = A * B
+    Value *A = II->getArgOperand(0);
----------------
According to other comments in the file, that should just be ` -A * -B -> A * B`
