There's a pattern of using:
...
set saved_gdbflags $GDBFLAGS
set GDBFLAGS "$GDBFLAGS ..."
<do something with GDBFLAGS>
set GDBFLAGS $saved_gdbflags
...
Simplify this by using save_vars:
...
save_vars { GDBFLAGS } {
set GDBFLAGS "$GDBFLAGS ..."
<do something with GDBFLAGS>
}
...
Tested on x86_64-linux.

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.

On s390x-linux (big endian), I run into:
...
(gdb) x /xh main^M
0x1000638 <main>: 0x0000^M
(gdb) FAIL: gdb.base/write_mem.exp: x /xh main
...
In contrast, on x86_64-linux (little endian), we have the expected:
...
(gdb) x /xh main^M
0x4004a7 <main>: 0x4242^M
(gdb) PASS: gdb.base/write_mem.exp: x /xh main
...
The problem is that the test-case hard-codes expectations about endiannes by
writing an int-sized value (4 bytes in this case) and then printing only a
halfword by using "/h" (so, two bytes).
If we print 4 bytes, we have for s390x:
...
0x1000638 <main>: 0x00004242^M
...
and for x86_64:
...
0x4004a7 <main>: 0x00004242^M
...
Fix this by removing the "/h".
Tested on x86_64-linux and s390x-linux.

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.

Update copyright year range in copyright header of all GDB files.

gdb/ChangeLog:
Update copyright year range in all GDB files.
|
|
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

Update copyright year range in all GDB files.

When opening a BFD for update, as gdb --write does, modifications to
anything but the contents of sections is restricted.
Do not try to write back any ELF headers in this case.
