[PATCH] D82550: [SLPVectorizer] handle vectorized lib functions

[Alexey Bataev via Phabricator via llvm-commits]

ABataev added inline comments.


================
Comment at: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp:5208
+          bool SrcMayWrite = BundleMember->Inst->mayWriteToMemory() &&
+                             !isVectorizableLibFunctionCall(BundleMember->Inst);
           unsigned numAliased = 0;
----------------
Still, this is a bad solution. Add proper attributes to the vector variants of the functions, so all memory access interfaces could properly handle such functions.
