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. %struct.struct_large_char = type { [8 x i8] } %struct.struct_large_char2 = type { [2 x i8], [8 x i8] } %struct.struct_small_char = type { [2 x i8] } %struct.struct_large_nonchar = type { [8 x i32] } %struct.struct_small_nonchar = type { [2 x i16] } define void @layout_ssp() ssp { entry: ; Expected stack layout for ssp is ; 180 large_char .
