; This test is fairly fragile. The goal is to ensure that "large" stack
|
||
|
|
; objects are allocated closest to the stack protector (i.e., farthest away
|
||
|
|
; from the Stack Pointer.) In standard SSP mode this means that large (>=
|
||
|
|
; ssp-buffer-size) arrays and structures containing such arrays are
|
||
|
|
; closet to the protector. With sspstrong and sspreq this means large
|
||
|
|
; arrays/structures-with-arrays are closest, followed by small (< ssp-buffer-size)
|
||
|
|
; arrays/structures-with-arrays, and then addr-taken variables.
|
||
|
|
;
|
||
|
|
; Ideally, we only want verify that the objects appear in the correct groups
|
||
|
|
; and that the groups have the correct relative stack offset. The ordering
|
||
|
|
; within a group is not relevant to this test. Unfortunately, there is not
|
||
|
|
; an elegant way to do this, so just match the offset for each object.
