This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* Read a table, line by line, from a file.
|
|
|
|
A table line has several forms:
|
|
|
|
Field line:
|
|
|
|
<text> { ":" <text> }
|
|
type == table_colon_entry
|
|
|
|
Fields points to a NULL terminated list of pointers.
|
|
|
|
Tab indented block:
|
|
|
|
<tab> <text> <nl> { <tab> <text> <nl> }
|
|
type == table_code_entry
|
|
|
|
The leading tab at the start of each line is discarded.
|
|
fields[i] is the i'th line with the <nl> discarded.
|
|
|
|
|
|
Code block:
|
|
|
|
"{" <ignore-text> <nl> { <text> <nl> } "}" <ignore-text> <nl>
|
|
type == table_code_entry
|
|
|
|
The leading/trailing {/} lines are discarded.
|
|
Lines containing two leading spaces have those spaces striped.
|
|
fields[i] is the i'th line with the <nl> discarded.
|
|
|
|
In addition, the table parser reconises and handles internally the
|
|
following (when not in a code block):
|
|
|
|
"#" <line-nr> '"' <file> '"'
|
|
|
|
As per CPP/CC, treat following lines as if they were taken from
|
|
<file> starting at <line-nr>
|
|
|
|
No support for CPP's "#if/#else/#endif" style conditions are
|
|
planned. */
