Confirmed.
Slightly reduced testcase (again, -Os -m32):
struct S { int s; } t;
int baz (void);
void fn (int, unsigned, int, unsigned, char);
static char
foo (signed x, unsigned y)
{
return x < 0 || y >= 32 ? 1 : x >> y;
}
long long
bar (long long x, long y)
{
return y < 0 ? 1LL : x - y;
}
void
test (int x, unsigned y, unsigned z, char w)
{
unsigned v[2];
fn (w || baz (), y, t.s, y, foo (bar (z, w) <= v[0], x));
}
