arsenm added a comment.

Still needs address space parameters



================
Comment at: llvm/include/llvm/Analysis/TargetTransformInfo.h:899-901
+  /// This function returns the maximum number of store operations permitted
+  /// to glue together during lowering of llvm.memcpy. The value is set by
+  //  the target at the performance threshold for such a replacement.
