Andrea Di Biagio 84fdff1b7f [DAG] Fix an assertion failure caused by an invalid cast in method 'BuildVectorSDNode::isConstantSplat' ... This patch renames method 'isConstantSplat' as 'getConstantSplatValue' (mainly for consistency reasons), and rewrites its logic to ensure that we always perform a legal 'cast<ConstantSDNode>'. Added test shift-combine-crash.ll to verify that DAGCombiner no longer crashes with an assertion failure in the attempt to simplify a vector shift by a vector of all undef counts. llvm-svn: 204536		2014-03-22 01:47:22 +00:00
