From 4669b5ae7e28a41346f816219f44c748a81d6696 Mon Sep 17 00:00:00 2001 From: Alex Samuel Date: Fri, 7 Apr 2000 03:33:15 +0000 Subject: [PATCH] Forgot the ChangeLog entry in this commit; here it is. * rtl.h (INSN_P): New macro. (successor_phi_fn): New typedef. (for_each_successor_phi): New prototype. (in_ssa_form): New variable. (PHI_NODE_P): Likewise. * flow.c (calculate_global_regs_live): Add to new_live_at_end from phi nodes in successors. (mark_used_regs): Add PHI case. (set_phi_alternative_reg): New function. (life_analysis): Assert that dead code elimination is not selected when in SSA form. * toplev.c (to_ssa_time): New variable. (from_ssa_time): Likewise. (compile_file): Zero to_ssa_time and from_ssa_time. Print time to convert to and from SSA. (rest_of_compilation): Time convert_to_ssa and convert_from_ssa. (print_time): Compute percent fraction as integer. * ssa.c (PHI_NODE_P): Moved to rtl.h. (convert_to_ssa): Check if we're already in SSA. Don't eliminate dead code in life_analysis. Rerun flow and life analysis at bottom. (eliminate_phi): Use canonical regnos when adding nodes. (mark_reg_in_phi): New function. (mark_phi_and_copy_regs): Likewise. (convert_from_ssa): Rerun life analysis at top. Use coalesced partition. Check for removing a phi node at the end of the block. (compute_coalesced_reg_partition): New function. (coalesce_regs_in_copies): Likewise. (coalesce_reg_in_phi): Likewise. (coalesce_regs_in_sucessor_phi_nodes): Likewise. (for_each_successor_phi): Likewise. (rename_context): New struct. (rename_block): Use a rename_context with rename_insn_1. When renaming sets of a subreg, emit a copy of the entire reg first. (rename_insn_1): Treat data as a rename_context *. Save current insn in set_data. (rename_set_data): Add field set_insn. * Makefile.in (HASHTAB_H): Move up in file. (OBSTACK_H): New macro. (collect2.o): Use OBSTACK_H in dependencies. (sdbout.o): Likewise. (emit-rtl.o): Likewise. (simplify-rtx.o): Likewise. (fix-header.o): Likewise. (OBJS): Add conflict.o. (conflict.o): New rule. * basic-block.h: Include partition.h. (conflict_graph): New typedef. (conflict_graph_enum_fn): Likewise. (conflict_graph_new): New prototype. (conflict_graph_delete): Likewise. (conflict_graph_add): Likewise. (conflict_graph_conflict_p): Likewise. (conflict_graph_enum): Likewise. (conflict_graph_merge_regs): Likewise. (conflict_graph_print): Likewise. (conflict_graph_compute): Likewise. * conflict.c: New file.
