Andrea Di Biagio b2f47c6a34 Teach DAGCombiner how to fold a SIGN_EXTEND_INREG of a BUILD_VECTOR of ... ConstantSDNodes (or UNDEFs) into a simple BUILD_VECTOR. For example, given the following sequence of dag nodes: i32 C = Constant<1> v4i32 V = BUILD_VECTOR C, C, C, C v4i32 Result = SIGN_EXTEND_INREG V, ValueType:v4i1 The SIGN_EXTEND_INREG node can be folded into a build_vector since the vector in input is a BUILD_VECTOR of constants. The optimized sequence is: i32 C = Constant<-1> v4i32 Result = BUILD_VECTOR C, C, C, C git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198084 91177308-0d34-0410-b5e6-96231b3b80d8		2013-12-27 20:20:28 +00:00
