* dbgcnt.def (cprop1, cprop2, gcse, jump_bypass): Remove
(cprop, hoist, pre, store_motion): New debug counters.
* tree-pass.h (pass_tracer): Move to list of gimple passes, it
is not an RTL pass anymore.
(pass_profiling): Remove extern decl for pass removed in 2005.
(pass_gcse, pass_jump_bypass): Remove.
* final.c (rest_of_clean_state): Set flag_rerun_cse_after_global_opts
to 0 for clean state.
* toplev.h (flag_rerun_cse_after_global_opts): Add extern declaration.
* cse.c (gate_handle_cse_after_global_opts,
rest_of_handle_cse_after_global_opts): New functions.
(pass_cse_after_global_opts): New pass, does local CSE.
* timevar.def (TV_GCSE, TV_CPROP1, TV_CPROP2, TV_BYPASS): Remove.
(TV_CPROP): New timevar.
* gcse.c (flag_rerun_cse_after_global_opts): New global variable.
(run_jump_opt_after_gcse, max_gcse_regno): Remove global vars.
(gcse_main, recompute_all_luids): Remove.
(compute_hash_table_work): Call max_reg_num instead of reading
max_gcse_regno.
(cprop_jump): Don't set run_jump_opt_after_gcse.
(constprop_register): Always allow to alter jumps.
(cprop_insn): Likewise.
(do_local_cprop): Likewise.
(local_cprop_pass): Likewise. Return non-zero if something changed.
(cprop): Remove function, fold interesting bits into one_cprop_pass.
(find_implicit_sets): Add note about missed optimization opportunity.
(one_cprop_pass): Rewrite to be "the" CPROP pass, called from the
pass_rtl_cprop execute function.
Don't bother tracking the pass number, each pass gets its own dumpfile
now anyway.
Always allow to alter jumpsand bypass jumps.
(bypass_block): Don't ignore regno >= max_gcse_regno, find_bypass_set
will just find no suitable set.
(pre_edge_insert): Fix dumping, this function is for PRE only.
(one_pre_gcse_pass): Rewrite to be "the" PRE pass, called from the
pass_rtl_pre execute function.
(hoist_code): Return non-zero if something changed. Keep track of
substitutions and insertions for statistics gathering similar to PRE.
(one_code_hoisting_pass): Rewrite to be "the" code hoisting pass,
called from the pass_rtl_hoist execute function. Show pass statistics.
(compute_store_table): Use max_reg_num directly instead of using the
formerly global max_gcse_regno.
(build_store_vectors): Likewise.
(replace_store_insn): Fix dumping.
(store_motion): Rename to ...
(one_store_motion_pass): ... this. Rewrite to be "the" STORE_MOTION
pass, called from the pass_rtl_store_motion execute function. Keep
track of substitutions and insertions for statistics gathering similar
to PRE.
(bypass_jumps): Remove, fold interesting bits into ...
(one_cprop_pass): ... this. Rewrite to be "the" CPROP pass, called
from the pass_rtl_cprop execute function.
(gate_handle_jump_bypass, rest_of_handle_jump_bypass,
pass_jump_bypass): Remove.
(gate_handle_gcse, rest_of_handle_gcse): Remove.
(gate_rtl_cprop, execute_rtl_cprop, pass_rtl_cprop): New.
(gate_rtl_pre, execute_rtl_pre, pass_rtl_pre): New.
(gate_rtl_hoist, execute_rtl_hoist, pass_rtl_hoist): New.
(gate_rtl_store_motion, execute_rtl_store_motion,
pass_rtl_store_motion): New.
* common.opt: Remove flag_cse_skip_blocks, adjust documentation to
make it clear that -fcse-skip-blocks is a no-op for backward compat.
* passes.c (init_optimization_passes): Remove pass_gcse and
pass_jump_bypass. Schedule cprop, pre, hoist, cprop, store_motion,
and cse_after_global_opts in place of pass_gcse. Schedule cprop
instead of pass_jump_bypass.
