3 ; This testcase exposed a problem with a previous handling of selecting
4 ; constant vectors (for vdelta). Originally a bitcast of a vsplat was
5 ; created (both being ISD, not machine nodes). Selection of vsplat relies
6 ; on its return type, and there was no way to get these nodes to be
7 ; selected in the right order, without getting the main selection algorithm
10 ; Make sure this compiles successfully.
