basic-block.h (pre_edge_lcm, [...]): Prototype for exported functions.
* basic-block.h (pre_edge_lcm, pre_edge_rev_lcm, compute_available):
Prototype for exported functions.
(pre_lcm, pre_rev_lcm): Remove prototypes.
* gcse.c (compute_ae_kill): Add ae_gen and ae_kill as parameters.
(compute_available): Move to lcm.c, and change parameter order.
(one_classic_gcse_pass): Call compute_ae_kill with parameters.
(pre_insert, s_preds, s_succs, num_preds, num_succs): Delete.
(gcse_main): No longer call compute_preds_succs. Rebuild the
set table after reach pre pass.
(pre_insert_map, pre_delete_map, edge_list): New.
(alloc_pre_mem): Allocate edge vectors.
(free_pre_mem): Delete edge vectors.
(compute_pre_data): Call new edge based lcm routines.
(process_insert_insn): New function.
(insert_insn_end_bb): Use it.
(pre_edge_insert): New function.
(pre_insert_copy_insn): Formatting fixes. Update BLOCK_END as
needed.
(pre_insert_copies): Revamp using new edge based lcm outputs.
(pre_delete): Likewise.
(one_pre_gcse_pass): Insert & remove fake edges to the exit
block.
(compute_code_hoist_vbeinout): New new edge based routines.
* lcm.c: Remove all the old LCM functions. Replace with new ones
that work with the new cfg datastructures and work with edges
instead of blocks.
