# RUN: not --crash llc -march=amdgcn -run-pass=verify -o - %s 2>&1 | FileCheck %s
# REQUIRES: amdgpu-registered-target

# Make sure that mismatched successors are caught when a _term
# instruction is used

# CHECK: *** Bad machine code: MBB exits via jump or conditional branch, but its target isn't a CFG successor! ***
# CHECK: *** Bad machine code: MBB has unexpected successors which are not branch targets, fallthrough, EHPads, or inlineasm_br targets. ***
