2004-08-18Hot/cold partitioning update patch.Caroline Tice1-1/+3
Hot/cold partitioning update patch. The problems that this patch attemptd to address/fix are: - Fix places where adding in_unlikely_executed_text to the enum data type "in_section" threw off switch case statements. - Make it work correctly (by turning it off) for functions where user specifies "__attribute__ section" - Make it work correctly (by turning it off) for linkonce sections - Make it work correctly with -ffunction-sections flag - Make it output correct cold section labels - Undo some changes to original assembly code generation - Turn off hot/cold partitioning in the presence of DWARF debugging (for the moment) - Turn off hot/cold partitioning for architectures that do not support named sections - Use variables rather than constants for cold section labels and names (to work correctly with -ffunction-sections, among other things) 2004-08-18 Caroline Tice <ctice@apple.com> * Makefile.in (STAGEFEEDBACK_FLAGS_TO_PASS) Add "-freorder-blocks-and-partition" to the flags used in second stage of profiledbootstrap. * bb-reorder.c (push_to_next_round_p): Add new variable, next_round_is_last; set and use variable to make sure, when partitioning, that the last trace construction round consists of all (and only) cold basic blocks. (rotate_loop): Don't copy blocks that end in a section crossing jump. (copy_bb): Correctly initialize "partition" of duplicated bb. (add_unlikely_executed_notes): Add a comment. (find_rarely_executed_basic_blocks_and_crossing_edges): Modify to make sure, if function contains hot blocks, that the successors of ENTRY_BLOCK_PTR are hot; also, only look for crossing edges if the architecture supports named sections.

* Makefile.in (cfghooks.o): Add TIMEVAR_H and toplev.h dependency. * basic-block.h (tidy_fallthru_edge, tidy_fallthru_edges, dump_bb, verify_flow_info): Declaration removed. * cfg.c (verify_flow_info, dump_bb): Moved to cfghooks.c. (debug_bb, debug_bb_n): Add argument to dump_bb call. * cfgcleanup.c (try_simplify_condjump, try_crossjump_to_edge, try_optimize_cfg, delete_unreachable_blocks): Use delete_basic_block instead of delete_block. * cfghooks.c: Include timevar.h and toplev.h. (cfg_hooks): Define here. (verify_flow_info, dump_bb): Moved from cfg.c. (redirect_edge_and_branch, redirect_edge_and_branch_force, split_block, split_block_after_labels, move_block_after, delete_basic_block, split_edge, create_basic_block, create_empty_bb, can_merge_blocks_p, merge_blocks, make_forwarder_block, tidy_fallthru_edge, tidy_fallthru_edges): New functions. * cfghooks.h (struct cfg_hooks): Added fields name, make_forwarder_block, tidy_fallthru_edge and move_block_after. Changed type of verify_flow_info, dump_bb, split_block fields. Renamed cfgh_split_edge and delete_block fields. (redirect_edge_and_branch, redirect_edge_and_branch_force, split_block, delete_block, split_edge, create_basic_block, can_merge_blocks_p, merge_blocks): Macros removed. (cfg_hooks): Do not export.

(cfg_layout_rtl_cfg_hooks): Declare. * cfgloop.c (update_latch_info, mfb_keep_just, mfb_keep_nonlatch): New functions. (canonicalize_loop_headers): Use new semantics of make_forwarder_block. (redirect_edge_with_latch_update): Removed. (make_forwarder_block): Moved to cfghooks.c, semantics changed. * cfgloopmanip.c (remove_bbs): Do not update dominators here. * cfgrtl.c (cfg_layout_split_block, rtl_split_block, rtl_dump_bb, rtl_delete_block, rtl_split_block, rtl_merge_blocks, tidy_fallthru_edge, rtl_split_edge, cfg_layout_delete_block, cfg_layout_merge_blocks, cfg_layout_split_edge): Partly moved to cfghooks.c. (rtl_create_basic_block): Coding style fix. (rtl_tidy_fallthru_edge, rtl_move_block_after, rtl_make_forwarder_block): New functions. (update_cfg_after_block_merging): Removed. (rtl_cfg_hooks, cfg_layout_rtl_cfg_hooks): Fill in new entries. * flow.c (verify_wide_reg, verify_local_live_at_start): Add argument to dump_bb. * ifcvt.c (merge_if_block, find_cond_trap, find_if_case_1, find_if_case_2): Don't update dominators. * timevar.def (TV_CFG_VERIFY): New. * loop-unswitch.c (unswitch_loop): Don't call add_to_dominance_info. * cfglayout.c (copy_bbs): Don't call add_to_dominance_info. * cfgloopmanip.c (split_loop_bb): Don't update dominators. (remove_bbs): Don't call remove_bbs. (create_preheader): Use make_forwarder_block. (mfb_keep_just, mfb_update_loops): New static functions. From-SVN: r76851
