;  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.

; FastISel was not setting the StackProtectorIndex when lowering
; Intrinsic::stackprotector and as a result the stack re-arrangement code was
; never applied.  This problem only shows up on non-Linux platforms because on
; Linux the stack protector cookie is loaded from a special address space which
; always triggers standard ISel.  Run a basic test to ensure that at -O0
; on a non-linux target the data layout rules are triggered.
