cfglayout.c (function_tail_eff_head): Rename to ...
* cfglayout.c (function_tail_eff_head): Rename to ... (function_footer): ... this one. (unlink_insn_chain): New functions. (label_for_bb): Only call block_label and emit debug message. (record_effective_endpoints): Actually unlink the headers and footers. (fixup_reorder_cahin): Re-insert the unlinked sequences. (cfg_layout_duplicate_bb): Use duplicate_insn_chain. * cfglayout.h (struct reorder_block_def): New fields footer/header; remove eff_head/eff_end. * rtl.h (set_first_insn): Declare. * emit-rtl.c (set_first_insn): New function. * cfglayout.c (fixup_reorder_chain): Dump duplicated (cfg_layout_can_duplicate_bb_p, cfg_layout_rerirect_edge, cfg_layout_duplicate_bb): New global function. (duplicate_insn_chain): New static function. * cfglayout.h (cfg_layout_can_duplicate_bb_p, cfg_layout_rerirect_edge, cfg_layout_duplicate_bb): Declare. (struct reorder_block_def): Add "original" field. * emit-rtl.c (emit_copy_of_insn_after): New function. * rtl.h (emit_copy_of_insn_after): Declare. * cfglayout.c (fixup_fallthru_exit_predecessor): Kill. (fixup_reorder_chain): properly handle edges to exit block. Wed May 8 11:10:31 CEST 2002 Zdenek Dvorak <rakdver@atrey.karlin.mff.cuni.cz> Jan Hubicka <jh@suse.cz> * basic-block.h (note_prediction_to_br_prob): declare. * c-semantics.c: Inlucde predit.h (expand_stmt): predict GOTO_STMT as not taken. * cfgcleanup.c: (delete_unreachable_blocks): Make global. (cleanup_cfg): Do not free tail_recursion_list. * cfgrtl.c (can_delete_note_p): Delete NOTE_INSN_PREDICTION. (flow_delete_block): Kill predictions past end of basic block. * output.h (delete_unreachable_blocks): Declare. * predict.c (predicted_by_p, process_note_predictions, process_note_prediction, last_block_p): New function. (estimate_probability): Bypass loop on PRED_CONTINUE; do not handle noreturn heuristics; kill PRED_RETURN; add PRED_EARLY_RETURN. * predict.def (PRED_CONTINUE, PRED_EARLY_RETURN, PRED_GOTO, PRED_CONST_RETURN, PRED_NEGATIVE_RETURN, PRED_NULL_RETURN): New. * predict.h (IS_TAKEN): New constant. * print-rtl.c (print_rtx): Pretty print NOTE_INSN_PREDICTION. * rtl.c (NOTE_INSN_PREDICTION): New. * rtl.h (NOTE_PREDICTION, NOTE_PREDICTION_ALG, NOTE_PREDICTION_FLAGS): New macro. (insn_note): add NOTE_INSN_PREDICTION. * sibcall.c (optimize_sibling_and_tail_recursive_call): Do not build CFG; free tail_recursion_label_list. * stmt.c: Include predict.h; (return_prediction): New. (expand_value_return): Use it. * toplev.c: Lower NOTE_INSN_PREDICTION before sibcall. From-SVN: r53285
