--- Comment #6 from Steven Bosscher <steven at gcc dot gnu.org> ---
What code is expected in this really old bug? Trunk x86-64 today:
int h(int *a);
struct G
{
int t;
int t1;
};
static int g1(struct G*);
int f1(int i, int j)
{
struct G nestedf1={i,j};
return g1(&nestedf1)+nestedf1.t1;
}
__attribute__((noinline))
static int g1(struct G *nestedf1)
{
return h(&nestedf1->t)+ nestedf1->t1;
}
g1(G*):
pushq %rbx
movq %rdi, %rbx
call h(int*)
addl 4(%rbx), %eax
popq %rbx
ret
f1(int, int):
subq $24, %rsp
movl %edi, 8(%rsp)
leaq 8(%rsp), %rdi
movl %esi, 12(%rsp)
call g1(G*)
addl 12(%rsp), %eax
addq $24, %rsp
ret
