; FIXME: The si scheduler crashes if when lane mask tracking is enabled, so
; we need to disable this when the si scheduler is being used.
; The only way the subtarget knows that the si machine scheduler is being used
; is to specify -mattr=si-scheduler.  If we just pass --misched=si, the backend
; won't know what scheduler we are using.
; RUN: llc -march=amdgcn --misched=si -mattr=si-scheduler < %s | FileCheck %s

; The test checks the "si" machine scheduler pass works correctly.
