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 file is unusual.
|
|
|
|
Because both libiberty and readline define xmalloc and friends, the
|
|
functions in this file can't appear in a library -- that will cause
|
|
link errors.
|
|
|
|
And, because we want to turn the common code into a library, this
|
|
file can't live there.
|
|
|
|
So, it lives in gdb and is built separately by gdb and gdbserver.
|
|
Please be aware of this when modifying it.
|
|
|
|
This also explains why this file includes common-defs.h and not
|
|
defs.h or server.h -- we'd prefer to avoid depending on the
|
|
GDBSERVER define when possible, and for this file it seemed
|
|
simple to do so. */
