Author: hjl Date: Fri Oct 30 14:32:26 2009 New Revision: 153750 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=153750 Log: Optimize -mstackrealign. gcc/ 2009-10-30 H.J. Lu <hongjiu...@intel.com> PR target/40836 * cfgexpand.c (expand_stack_alignment): Call update_stack_boundary first. Move assert on stack_alignment_estimated just before setting stack_realign_needed. (gimple_expand_cfg): Initialize stack_alignment_estimated to 0. Don't call update_stack_boundary. * config/i386/i386.c (ix86_minimum_incoming_stack_boundary): New. (verride_options): Don't check ix86_force_align_arg_pointer here. (ix86_function_ok_for_sibcall): Use it. (ix86_update_stack_boundary): Likewise. * config/i386/i386.h (STACK_REALIGN_DEFAULT): Update comments. gcc/testsuite/ 2009-10-30 H.J.
