A ValueType in a pattern dag is a type cast, and GetNumNodeResults should handle it (the type cast has only one result). This comes up, for example, during the type checking of pattern fragments, for example, AArch64's Neon_combine_2d fragment is: dag Operands = (ops node:$Rm, node:$Rn); dag Fragment = (v2f64 (concat_vectors (v1f64 node:$Rm), (v1f64 node:$Rn))); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198347 91177308-0d34-0410-b5e6-96231b3b80d8
