; RUN: llc -march=hexagon < %s
; REQUIRES: asserts
; The test case validates the fact that if the modifier register value "-268430336"
; is passed as target constant, then the compiler must not assert.
; This test also validates that the VLIW Packetizer does not bail out the compilation
; with "Unknown .new type" when attempting to validate if the circular store can be
; converted to a new value store.
