r181236 - in /trunk/gcc: ChangeLog config/i386/...


Author: jakub
Date: Wed Nov  9 21:28:57 2011
New Revision: 181236

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=181236
Log:
	* function.h (requires_stack_frame_p): New prototype.
	* function.c (requires_stack_frame_p): No longer static.
	* config/i386/i386.c (ix86_finalize_stack_realign_flags): If
	stack_realign_fp was just a conservative guess for a function
	which doesn't use sp/fp/argp at all, clear frame_pointer_needed
	and stack realignment.
