Another test, trigger with -Os option.
$ cat foo.i
int a;
long long b() {}
int c() {
if (b())
a = 1;
}
$gcc -m32 -mpreferred-stack-boundary=2 -Os -c foo.i

$ cat foo.c
long long c(long long x) {}
int a() { long long b = c(b); }

On i386, we don't do dynamic stack realignment for long long objects with
-mpreferred-stack-boundary=2 on purpose. A backend should be allowed to
opt-out
