Chandler Carruth d0de9868a6 [SDAG] At the suggestion of Hal, switch to an output parameter that ... tracks which elements of the build vector are in fact undef. This should make actually inpsecting them (likely in my next patch) reasonably pretty. Also makes the output parameter optional as it is clear now that *most* users are happy with undefs in their splats. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212581 91177308-0d34-0410-b5e6-96231b3b80d8		2014-07-09 00:41:34 +00:00
