From d743aba2f4aebf422c08b41db532d0c78603a97f Mon Sep 17 00:00:00 2001 From: steven Date: Mon, 27 Apr 2009 17:21:27 +0000 Subject: * 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. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@146848 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/passes.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'gcc/passes.c') diff --git a/gcc/passes.c b/gcc/passes.c index 60a24866265..312dfa9db72 100644 --- a/gcc/passes.c +++ b/gcc/passes.c @@ -729,7 +729,12 @@ init_optimization_passes (void) NEXT_PASS (pass_df_initialize_opt); NEXT_PASS (pass_cse); NEXT_PASS (pass_rtl_fwprop); - NEXT_PASS (pass_gcse); + NEXT_PASS (pass_rtl_cprop); + NEXT_PASS (pass_rtl_pre); + NEXT_PASS (pass_rtl_hoist); + NEXT_PASS (pass_rtl_cprop); + NEXT_PASS (pass_rtl_store_motion); + NEXT_PASS (pass_cse_after_global_opts); NEXT_PASS (pass_rtl_ifcvt); /* Perform loop optimizations.
