PR c++/53743
* ifcvt.c (find_if_case_1): Replace BB_COPY_PARTITION with assert
as this is now done by redirect_edge_and_branch_force.
* function.c (thread_prologue_and_epilogue_insns): Insert new bb after
barriers, and fix interaction with splitting.
* emit-rtl.c (try_split): Copy REG_CROSSING_JUMP notes.
* cfgcleanup.c (try_forward_edges): Fix early return value to properly
reflect changes made in the routine.
* bb-reorder.c (emit_barrier_after_bb): Move to cfgrtl.c.
(fix_up_fall_thru_edges): Remove incorrect check for bb layout order
since this is called in cfglayout mode, and replace partition fixup
with assert as that is now done by force_nonfallthru_and_redirect.
(add_reg_crossing_jump_notes): Handle the fact that some jumps may
already be marked with region crossing note.
(insert_section_boundary_note): Make non-static, gate on flag
has_bb_partition, rewrite to also check for multiple partitions.
(rest_of_handle_reorder_blocks): Remove call to
insert_section_boundary_note, now done later during free_cfg.
(duplicate_computed_gotos): Don't duplicate partition crossing edge.
* bb-reorder.h (insert_section_boundary_note): Declare.
* Makefile.in (cfgrtl.o): Depend on bb-reorder.h
* cfgrtl.c (rest_of_pass_free_cfg): If partitions exist
invoke insert_section_boundary_note.
(try_redirect_by_replacing_jump): Remove unnecessary
check for region crossing note.
(fixup_partition_crossing): New function.
(rtl_redirect_edge_and_branch): Fixup partition boundaries.
(emit_barrier_after_bb): Move here from bb-reorder.c, handle insertion
in non-cfglayout mode.
(force_nonfallthru_and_redirect): Fixup partition boundaries,
remove old code that tried to do this. Emit barrier correctly
when we are in cfglayout mode.
(last_bb_in_partition): New function.
(rtl_split_edge): Correctly fixup partition boundaries.
(commit_one_edge_insertion): Remove old code that tried to
fixup region crossing edge since this is now handled in
split_block, and set up insertion point correctly since
block may now end in a jump.
(verify_hot_cold_block_grouping): Guard against checking when not in
linearized RTL mode.
(rtl_verify_edges): Add checks for incorrect/missing REG_CROSSING_JUMP
notes.
(rtl_verify_flow_info_1): Move verify_hot_cold_block_grouping to
rtl_verify_flow_info, so not called in cfglayout mode.
(rtl_verify_flow_info): Move verify_hot_cold_block_grouping here.
(fixup_reorder_chain): Remove old code that attempted to fixup region
crossing note as this is now handled in force_nonfallthru_and_redirect.
(duplicate_insn_chain): Don't duplicate switch section notes.
(rtl_can_remove_branch_p): Remove unnecessary check for region crossing
note.
* basic-block.h (emit_barrier_after_bb): Declare.
* testsuite/gcc.dg/tree-prof/va-arg-pack-1.c: Cloned from c-torture, made
into -freorder-blocks-and-partition test.
* testsuite/gcc.dg/tree-prof/comp-goto-1.c: Ditto.
* testsuite/gcc.dg/tree-prof/20041218-1.c: Ditto.
* testsuite/gcc.dg/tree-prof/pr52027.c: Use -O2.
* testsuite/gcc.dg/tree-prof/pr50907.c: Ditto.
* testsuite/gcc.dg/tree-prof/pr45354.c: Ditto.
* testsuite/g++.dg/tree-prof/partition2.C: Ditto.
* testsuite/g++.dg/tree-prof/partition3.C: Ditto.
