; Test that the memoperands for instructions in the epilog are updated
|
||
|
|
; correctly. Previously, the pipeliner updated the offset for the memoperands
|
||
|
|
; in the epilog. But, the value of the offset is incorrect when control flow
|
||
|
|
; branches around the kernel.
|
||
|
|
|
||
|
|
; In this test, we check that a load and store to the same location are not
|
||
|
|
; swapped due to a bad offset in the memoperands. The store and load are both
|
||
|
|
; to r29+32. If the memoperands are updated incorrectly, these are swapped.
