Confirmed, it is a little more obvious on ppc-darwin:
_bar:
mflr r0
stmw r29,-12(r1)
stw r0,8(r1)
stwu r1,-96(r1)
lis r29,ha16(___stack_chk_guard)
la r29,lo16(___stack_chk_guard)(r29)
lwz r0,0(r29)
stw r0,76(r1)
li r0,0
add r3,r3,r4
bl _foo
lwz r0,76(r1)
lwz r2,0(r29)
xor. r0,r0,r2
li r2,0
beq+ cr0,L3
bl ___stack_chk_fail
L3:
addi r1,r1,96
lwz r0,8(r1)
mtlr r0
lmw r29,-12(r1)
blr
