That's not my reading of ix86_minimum_incoming_stack_boundary:
/* Prefer the one specified at command line. */
incoming_stack_boundary = ix86_user_incoming_stack_boundary;
/* In 32bit, use MIN_STACK_BOUNDARY for incoming stack boundary
if -mstackrealign is used, it isn't used for sibcall check and
estimated stack alignment is 128bit. */
else if (!sibcall
&& crtl->stack_alignment_estimated == 128)
incoming_stack_boundary = MIN_STACK_BOUNDARY;
incoming_stack_boundary = ix86_default_incoming_stack_boundary;

Thanks, now applied. I presume I need to add a blurb to changes.html.
