Correct fixes for various hot/cold partitioning concerns.
2005-04-27 Caroline Tice <ctice@apple.com> * bb-reorder.c (find_rarely_executed_basic_blocks_and_crossing_edges): Remove targetm.have_named_sections test. (fix_edges_for_rarely_executed_code): Likewise. (insert_section_boundary_note): Likewise. (reorder_basic_blocks): Check partitioning flag before calling verify_hot_cold_block_grouping. * dbxout.c (dbxout_function_end): Get hot/cold section labels from the function struct rather than global variables. * dwarf2out.c (COLD_TEXT_SECTION_LABEL): New macro. (COLD_END_LABEL): Likewise (cold_text_section_label): New static global variable. (cold_end_label): Likewise. (dwarf2out_switch_text_section): Get hot/cold section labels from the function struct rather than global variables; test to make sure cfun is defined. (output_aranges): Use cold_text_section_label and cold_end_label; check partitioning flag before putting out delta. (output_ranges): Remove incorrect code attempting to use hot/cold labels. (output_line_info): Get cold section label from function struct; test to make sure cfun is defined. (add_location_or_const_value_attribute): Likewise. (dwarf2out_var_location): Likewise. (dwarf2out_init): Generate cold_text_section_label and cold_end_label; write out cold_text_section_label if partition flag is set. (dwarf2out_finish): Write out cold_end_label if partition flag is set; * function.h (struct function): Add new fields to point to hot/cold section labels: hot_section_label, cold_section_label, hot_section_end_label and cold_section_end_label; also add new field for cold text section name, unlikely_text_section_name. * opts.c (decode_options): Turn off partitioning flag if !targetm.have_named_sections. * output.h (hot_section_label): Remove. (hot_section_end_label): Remove. (cold_section_end_label): Remove. (unlikely_section_label): Remove. (unlikely_text_section_name): Remove. * passes.c (rest_of_handle_final): Remove extra blank line. * varasm.c (unlikely_section_label): Remove. (hot_section_label): Remove. (hot_section_end_label): Remove. (cold_section_end_label): Remove. (unlikely_text_section_name): Remove. (initialize_cold_section_name): Modify to call targetm.strip_name_encoding; to store cold section name in current function struct, if it exists; and to only use the decl_section_name if flag_named_sections is true. (unlikely_text_section): Modify to get section name out of current function struct, if there is one; otherwise build it from UNLIKELY_EXECUTED_TEXT_SECTION_NAME. (in_unlikely_text_section): Likewise. (named_section): Modify to get/put cold section name in current function struct, if there is one. (function_section): Change 'bool unlikely' to 'int reloc'; check targetm.have_named_sections before calling named_section. (current_function_section): Likewise. (assemble_start_function): Modify to get/put unlikely_text_section_name in current function struct; modify to get hot/cold section labels from function struct; initialize labels using ASM_GENERATE_INTERNAL_LABEL; test partitioning flag before writing out hot section label. (assemble_end_function): Test partitioning flag before writing out hot/cold section labels. (default_section_type_flags_1): Get cold text section name from function struct if there is one; Set flags correctly for cold text section if there is not a current function struct. From-SVN: r98885
