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 test creates a shared library and a main program which uses
|
|
# that library, extracts the debug info of the library to a separate
|
|
# file, and then tests that a symbol from the shared library is
|
|
# accessible using both absolute and relative settings of
|
|
# LD_LIBRARY_PATH.
|
|
|
|
# This test needs to change the environment in which the test program
|
|
# is run, specifically the setting of LD_LIBRARY_PATH. GDB can adjust
|
|
# this setting for both native and extended-remote targets, but not
|
|
# for targets to which GDB connects after the program has already
|
|
# started. Therefore, this test won't work for targets which use
|
|
# "target remote".
