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

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added inline comments.


================
Comment at: llvm/include/llvm/Analysis/VectorUtils.h:82
+/// Return true if the input value is known to be a vector with all identical
+/// elements (potentially including undefined elements).
+bool isSplatValue(const Value *V, unsigned Depth = 0);
----------------
Make it clear that this is more powerful than getSplatValue ?
