| | | | | | | | | | Even looking at the revision history I couldn't quite piece together why this cast was ever written in the first place, but I assume it was because of some change in the inheritance, perhaps this function was reimplemented in a derived type & this caller was meant to get the base version (& it wasn't virtual)? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162301 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed DAGCombiner bug (found and localized by James Malloy):Stepan Dyatkovskiy2012-08-201-3/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DAGCombiner tries to optimise a BUILD_VECTOR by checking if it consists purely of get_vector_elts from one or two source vectors. If so, it either makes a concat_vectors node or a shufflevector node. However, it doesn't check the element type width of the underlying vector, so if you have this sequence: Node0: v4i16 = ... Node1: i32 = extract_vector_elt Node0 Node2: i32 = extract_vector_elt Node0 Node3: v16i8 = BUILD_VECTOR Node1, Node2, ... It will attempt to: Node0: v4i16 = ... NewNode1: v16i8 = concat_vectors Node0, ... Where this is actually invalid because the element width is completely different. This causes an assertion failure on DAG legalization stage. Fix: If output item type of BUILD_VECTOR differs from input item type. Make concat_vectors based on input element type and then bitcast it to the output vector type. So the case described above will transformed to: Node0: v4i16 = ... NewNode1: v8i16 = concat_vectors Node0, ... NewNode2: v16i8 = bitcast NewNode1 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162195 91177308-0d34-0410-b5e6-96231b3b80d8
