9fb3243411 Hot/cold partitioning update patch. 
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.
        (mark_bb_for_unlikely_executed_section): Modify to always
        insert the NOTE_INSN_UNLIKELY_EXECUTED_CODE immediately after
        the basic block note insn.
        (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.

        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.
        (rtl_split_block): Make sure newly created bb gets correct
        partition.

        attempting to cross section boundaries.
        (force_nonfallthru_and_redirect): Only do partition fix up if
        architecture supports named sections.
        (rtl_split_edge): Make sure newly created bb ends up in
        correct partition.
        (commit_one_edge_insertion): Remove code that incorrectly
        updated basic block partition; Make sure partition fix up only
        happens if architecture supports named sections and it's not
        already done.
        (rtl_verify_flow_info_1): Fix if-condition on test/error
        condition that fallthru edges are not allowed to cross section
        boundaries.
        * defaults.h (NORMAL_TEXT_SECTION_NAME): Remove this.
        * final.c (final_scan_insn): Remove redundant test from if-statement;
        change calls to text_section into calls to function_section; add code

        partition.
        (if_convert): Add targetm.have_named_sections to test.

        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.

        (in_unlikely_text_section):  Modify to work correctly with named_section
        and to use unlikely_text_section_name.
        (named_section):  Add code to work properly with cold section.
        (function_section): Clean up if-statement.
        * config/darwin.c (darwin_asm_named_section): Return to original code,
