yup, i see something new :)

please look at line 12137 of i8259.i:

__attribute__((regparm(0))) void call_do_IRQ(void); __asm__(...

as you can see there is a semicolon after call_do_IRQ(void)
and following asm statement isn't treated as a function body.
in this way -O1 -f{no-}unit-at-a-time accidentally produces
different code. it's not a gcc bug.
