While doing the psymtab-sharing patchset, I avoided renaming variables
unnecessarily to avoid adding noise to patches, but I'd like to do it
now. Basically, we have these dwarf2 per-something structures:
- dwarf2_per_objfile
- dwarf2_per_bfd
- dwarf2_per_cu_data
I named the instances of dwarf2_per_bfd `per_bfd` and most of instances
of dwarf2_per_cu_data are called `per_cu`. Most pre-existing instances
of dwarf2_per_objfile are named `dwarf2_per_objfile`. For consistency
with the other type, I'd like to rename them to just `per_objfile`. The
`dwarf2_` prefix is superfluous, since it's already clear we are in
dwarf2 code. It also helps reducing the line wrapping by saving 7
precious columns.
gdb/ChangeLog:
* dwarf2/comp-unit.c, dwarf2/comp-unit.h, dwarf2/index-cache.c,
dwarf2/index-cache.h, dwarf2/index-write.c,
dwarf2/index-write.h, dwarf2/line-header.c,
dwarf2/line-header.h, dwarf2/macro.c, dwarf2/macro.h,
dwarf2/read.c, dwarf2/read.h: Rename struct dwarf2_per_objfile
variables and fields from `dwarf2_per_objfile` to just
`per_objfile` throughout.

This moves some more code out of read.c and into line-header.c.
dwarf_decode_line_header is split into two -- the part remaining in
read.c handles interfacing to the dwarf2_cu; while the part in
line-header.c (more or less) purely handles the actual decoding.

* dwarf2/line-header.h (dwarf_decode_line_header): Declare.
* dwarf2/read.c
(dwarf2_statement_list_fits_in_line_number_section_complaint):
Move to line-header.c.
(read_checked_initial_length_and_offset, read_formatted_entries):
Likewise.
(dwarf_decode_line_header): Split into two.
* dwarf2/line-header.c
(dwarf2_statement_list_fits_in_line_number_section_complaint):
Move from read.c.
(read_checked_initial_length_and_offset, read_formatted_entries):
Likewise.
(dwarf_decode_line_header): New function, split from read.c.
This changes a few line_header methods to be const. In some cases, a
const overload is added.

* dwarf2/line-header.h (struct line_header) <is_valid_file_index,
file_names_size, file_full_name, file_file_name>: Use const.
<file_name_at, file_names>: Add const overload.
* dwarf2/line-header.c (line_header::file_file_name)
(line_header::file_full_name): Update.
This moves the line_header class to a pair of new files, making
dwarf2/read.c somewhat smaller.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.h (dwarf_line_debug): Declare.
* Makefile.in (COMMON_SFILES): Add dwarf2/line-header.c.
* dwarf2/read.c: Move line_header code to new files.
(dwarf_line_debug): No longer static.
* dwarf2/line-header.c: New file.
* dwarf2/line-header.h: New file.
