------- Comment #1 from hjl dot tools at gmail dot com 2009-02-10 20:46 -------
The problem is
static rtx
ix86_get_drap_rtx (void)
{
if (ix86_force_drap || !ACCUMULATE_OUTGOING_ARGS)
crtl->need_drap = true;
-Os turns off ACCUMULATE_OUTGOING_ARGS, which turns on DRAP. Does
ACCUMULATE_OUTGOING_ARGS really increase code size?
