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.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.

The test-case gdb.ada/dgopt.exp uses the -gnatD switch, in combination with
-gnatG.
This causes the source file $src/gdb/testsuite/gdb.ada/dgopt/x.adb to be
expanded into $build/gdb/testsuite/outputs/gdb.ada/dgopt/x.adb.dg, and the
debug information should refer to the x.adb.dg file.
That is the case for the .debug_line part:
...
The Directory Table is empty.
The File Name Table (offset 0x1c):
Entry Dir Time Size Name
1 0 0 0 x.adb.dg
...
but not for the .debug_info part:
...
<11> DW_AT_name : $src/gdb/testsuite/gdb.ada/dgopt/x.adb
<15> DW_AT_comp_dir : $build/gdb/testsuite/outputs/gdb.ada/dgopt
...
Filed as PR gcc/103436.
In C we can generate similar debug information, using a source file that does
not contain any code, but includes another one that does:
...
$ cat gdb/testsuite/gdb.base/include-main.c
#include "main.c"
...
such that in the .debug_line part we have:
...
The Directory Table (offset 0x1c):
1 /home/vries/gdb_versions/devel/src/gdb/testsuite/gdb.base
The File Name Table (offset 0x57):
Entry Dir Time Size Name
1 1 0 0 main.c
...
and in the .debug_info part:
...
<11> DW_AT_name : $src/gdb/testsuite/gdb.base/include-main.c
<15> DW_AT_comp_dir : $build/gdb/testsuite
...
Add a C test-case that mimics gdb.ada/dgopt.exp, that is:
- generate debug info as described above,
- issue a list of a line in include-main.c, while the corresponding
CU is not expanded yet.
Tested on x86_64-linux.
