; 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.
