--- Comment #2 from Eric Botcazou ---
I can reproduce the bug on Solaris with the following testcase:
extern void abort ();
static void __attribute__((noinline))
set (unsigned long *l)
{
*l = 31;
}
int main (void)
{
unsigned long l;
int i;
set (&l);
i = (int) l;
l = (unsigned long)(unsigned int)(2 << i);
if (l != 0)
abort ();
return 0;
}
