[PATCH] D63138: [Analysis] add isSplatValue() for vectors in IR

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

Seems ok to me



================
Comment at: llvm/lib/Analysis/VectorUtils.cpp:350
+  Value *X, *Y, *Z;
+  if (match(V, m_BinOp(m_Value(X), m_Value(Y))))
+    return isSplatValue(X, Depth) && isSplatValue(Y, Depth);
----------------
also fneg
also some intrinsics - overflow, saturating, ...
