gcse.c (post_dominators): Kill.
* 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. From-SVN: r30437
