* dwarf2out.c (struct dw_fde_struct): Remove dw_fde_hot_section_label,
dw_fde_hot_section_end_label, dw_fde_unlikely_section_label,
dw_fde_unlikely_section_end_label, cold_in_std_section,
dw_fde_switched_sections and dw_fde_switched_cold_to_hot fields.
Add dw_fde_second_begin, dw_fde_second_end and second_in_std_section
fields.
(output_fde): Use dw_fde_second_{begin,end} if second is
true, otherwise dw_fde_{begin,end}.
(output_call_frame_info): Test dw_fde_second_begin != NULL
instead of dw_fde_switched_sections.
(dwarf2out_begin_prologue): Stop initializing removed dw_fde_struct
fields, initialize new fields. Initialize in_std_section
unconditionally from the first partition.
(dwarf2out_end_epilogue): Don't override dw_fde_end when
dw_fde_second_begin is non-NULL.
(dwarf2out_switch_text_section): Stop initializing removed
dw_fde_struct fields, initialize new fields, initialize
also dw_fde_end here. Set dw_fde_switch_cfi even when
dwarf2out_do_cfi_asm (). Call var_location_switch_text_section.
(struct var_loc_list_def): Add last_before_switch field.
(arange_table, arange_table_allocated, arange_table_in_use,
ARANGE_TABLE_INCREMENT, add_arange): Removed.
(size_of_aranges): Count !in_std_section and !second_in_std_section
hunks in fdes, instead of looking at arange_table_in_use.
(output_aranges): Add aranges_length argument, don't call
size_of_aranges here. Instead of using aranges_table*
emit ranges for fdes when !in_std_section resp.
!second_in_std_section.
(dw_loc_list): Break ranges crossing section switch.
(convert_cfa_to_fb_loc_list): Likewise. If switched sections,
use dw_fde_second_end instead of dw_fde_end as end of last
range.
(gen_subprogram_die): Don't call add_arange. Use
dw_fde_{begin,end} for first partition and if switched
section dw_fde_second_{begin,end} for the second.
(var_location_switch_text_section_1,
var_location_switch_text_section): New functions.
(dwarf2out_begin_function): Initialize cold_text_section even
when function_section () isn't text_section.
(prune_unused_types): Don't walk arange_table.
(dwarf2out_finish): Don't needlessly test
flag_reorder_blocks_and_partition when testing cold_text_section_used.
If info_section_emitted, call size_of_aranges and if it indicates
non-empty .debug_aranges, call output_aranges with the computed
size. Stop using removed dw_fde_struct fields, use
dw_fde_{begin,end} for first partition and dw_fde_second_{begin,end}
for second.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
