rampitec added inline comments.


================
Comment at: llvm/test/CodeGen/AMDGPU/loop_break.ll:45
+; GCN:      s_or_b64          [[ACCUM_MASK]], [[AND_MASK]], [[ACCUM_MASK]]
+; GCN:      s_andn2_b64       exec, exec, [[ACCUM_MASK]]
 ; GCN-NEXT: s_cbranch_execnz  [[LOOP_ENTRY]]
----------------
Probably use of GCN-NEXT here and s_or_b64 above will constitute for the proper testcase.
