2004-08-18Hot/cold partitioning update patch.Caroline Tice1-0/+10
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.

(fix_crossing_unconditional_branches): Remove extra space. (fix_edges_for_rarely_executed_code): Modify to only do partitioning work if the architecture supports named sections. (reorder_basic_blocks): Modify to only add NOTE_INSN_UNLIKELY_EXECUTED_CODE notes if the architecture supports named sections. * c-common.c (handle_section_attribute): Initialize new global variable, user_defined_section_attribute, to true if user has specified one. * cfgcleanup.c (try_forward_edges): Modify to not attempt to forward edges that cross section boundaries. * cfglayout.c (fixup_reorder_chain): Modify to only fix up partitioning information if the architecture supports named sections. * cfgrtl.c (target.h): Add statement to include this.

(if_convert): Add targetm.have_named_sections to test. * output.h (unlikely_section_label): Extern declaration for new global variable. (unlikely_text_section_name): Likewise. * opts.c (decode_options): If both partitioning and DWARF debugging are turned on, issue a warning that this doesn't work, and change partitiong to basic block reordering (without hot/cold partitions). * passes.c (rest_of_handle_final): Re-set new global variable, user_defined_section_attribute, to false. (rest_of_compilation): Change options for calling partitioning function: Don't call if the user defined the section attribute, and don't call if DECL_ONE_ONLY is true for the current function. * predict.c (choose_function_section): Return immediately if we are doing hot/cold partitioning (i.e. let the basic block partitioning determine where the function belongs). * reg-stack.c (emit_swap_insn): Add condition to step over NOTE_INSN_UNLIKELY_EXECUTED_CODE notes. * toplev.c (user_defined_section_attribute): New global variable. * toplev.h (user_defined_section_attribute): Extern declaration for new global variable. * varasm.c (unlikely_section_label): New global variable.
