2 ; This test is fairly fragile. The goal is to ensure that "large" stack
3 ; objects are allocated closest to the stack protector (i.e., farthest away
4 ; from the Stack Pointer.) In standard SSP mode this means that large (>=
5 ; ssp-buffer-size) arrays and structures containing such arrays are
6 ; closet to the protector. With sspstrong and sspreq this means large
7 ; arrays/structures-with-arrays are closest, followed by small (< ssp-buffer-size)
8 ; arrays/structures-with-arrays, and then addr-taken variables.
9 ;
10 ; Ideally, we only want verify that the objects appear in the correct groups
11 ; and that the groups have the correct relative stack offset. The ordering
12 ; within a group is not relevant to this test. Unfortunately, there is not
13 ; an elegant way to do this, so just match the offset for each object.

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