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.

architecture supports named sections.
(rtl_split_edge): Make sure newly created bb ends up in
correct partition.

updated basic block partition; Make sure partition fix up only
happens if architecture supports named sections and it's not
already done.

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
to only to partitioning fix up if architecture supports named
sections.

partition.

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).

NOTE_INSN_UNLIKELY_EXECUTED_CODE notes.

global variable.
