[PATCH] D62272: [LoopUtils][SLPVectorizer] clean up management of fast-math-flags

[Vasileios Porpodas via Phabricator via llvm-commits]

vporpo added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:6298
+    if (!IsPairwiseReduction) {
+      // FIXME: The builder should already have an FMF guard, and this should
+      //        not be hard-coded to 'fast'.
----------------
If I am not mistaken, the flags are set to 'fast' by `tryToReduce()` line 6111. So maybe it is better to check them with an assert() ?
