i386.c (ix86_output_main_function_alignment_hack): New function.
* i386.c (ix86_output_main_function_alignment_hack): New function.
(TARGET_ASM_FUNCTION_PROLOGUE): Default to it.
* flow.c (mark_dfs_back_edges): Move from loop_p ; mark back
edges by EDGE_DFS_BACK flag.
(dump_edge_info): Add dfs_back flag.
* basic-block.h (EDGE_DFS_BACK): New constant.
(mark_dfs_back_edges): Declare.
* alias.c (loop_p): Remove.
(mark_constant_function): Use mark_dfs_back_edges.
* reg-stack.c (block_info_def): Add predecesors counter and stack_out.
(reg_to_stack): Call mark_dfs_back_edges; count the predecesors.
(compensate_edge): Break out from ...
(convert_regs_1): ... here; do smart choosing of stack_out to copy.
(convert_regs_2): Set block_done once block is really done;
Do updating of the predecesors counts.
* toplev.c (rest_of_compilation): Recompute block_for_insn
before post-reload cfg_cleanup.
* function.c (thread_prologue_epilogue_insns):
Call set_block_for_new_insns when emitting prologue directly.
