	gcc            : ChangeLog gcse.c haifa-sched.c flow.c 
	                 basic-block.h 

Log message:
	* gcse.c (post_dominators): Kill.
	(alloc_code_hoist_mem, free_code_hoist_mem); Kill post_dominators.
	(compute_code_hoist_data): Use compute_flow_dominators.  Do not
	pass in a pdom array since we do not need pdoms.
	* haifa-sched.c (schedule_insns): Similarly.
	* flow.c (compute_dominators): Remove dead function.
	(compute_flow_dominators): Do not compute doms or pdoms if the
	caller does not request them.  Split up loop to build doms and
	pdoms.  Use a worklist to compute doms and pdoms.
	* basic-block.h (compute_dominators): Remove prototype.
