# RUN: llc -march=amdgcn -mcpu=gfx900 -start-before=twoaddressinstruction %s -o - | FileCheck %s -check-prefix=GCN

# Wait to sxpand SI_INDIRECT sequences that use VGPR indexing until after
# register allocation. We don’t want to reschedule the mode switching or to
# have any instructions inserted within the sequence. The Two-Address
# instruction pass could insert bad copies here if it is expanded too early.
