+; 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.

+; RUN: | FileCheck --check-prefix=FAST-NON-LIN %s
+; 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.
