; RUN: llc -march=hexagon < %s | FileCheck %s

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

; Make sure this compiles successfully.
; CHECK: call f1
