Arnold Schwaighofer c46e2df74c DAGCombiner: Fold pointless truncate, bitcast, buildvector series ... (2xi32) (truncate ((2xi64) bitcast (buildvector i32 a, i32 x, i32 b, i32 y))) can be folded into a (2xi32) (buildvector i32 a, i32 b). Such a DAG would cause uneccessary vdup instructions followed by vmovn instructions. We generate this code on ARM NEON for a setcc olt, 2xf64, 2xf64. For example, in the vectorized version of the code below. double A[N]; double B[N]; void test_double_compare_to_double() { int i; for(i=0;i<N;i++) A[i] = (double)(A[i] < B[i]); } radar://13191881 Fixes bug 15283. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175670 91177308-0d34-0410-b5e6-96231b3b80d8		2013-02-20 21:33:32 +00:00
