[PATCH] D139340: [InstCombine] Bubble vector.reverse of compare operands to their result.

[David Sherwood via Phabricator via llvm-commits]

david-arm added inline comments.


================
Comment at: llvm/lib/Transforms/InstCombine/InstCombineCompares.cpp:6098
+    if (auto *I = dyn_cast<Instruction>(V))
+      I->copyIRFlags(&Cmp);
+    Module *M = Cmp.getModule();
----------------
If possible it would be nice to have a `fcmp fast` test that showed the propagation of flags here.
