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. 14; RUN: llc < %s -disable-fp-elim -mtriple=x86_64-unknown-unknown -O0 -mcpu=corei7 -o - \ 15; RUN: | FileCheck --check-prefix=FAST-NON-LIN %s 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.
