; This test failed with verify machine instrs due to incorrect kill flags on the add instructions
|
||
|
|
; generated by the GEPs. The first add generated killed the vreg for the #6680 constant which should
|
||
|
|
; be correct. However, the second add is also a constant expression and the local value save area grows
|
||
|
|
; down. This meant the next use of the vreg for #6680 was after the first which had killed it.
