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 testcase checks that if a function has the DW_AT_calling_convention
|
|
# attribute with the value DW_CC_nocall, then GDB will not:
|
|
# - call the function,
|
|
# - try to access the value returned by the function when using the finish
|
|
# command,
|
|
# - force a user-provided return value when using the return command.
|
|
#
|
|
# In every case, GDB prints a message to the user indicating the issue. For
|
|
# the return command, GDB asks the user to confirm if the specified value
|
|
# should be forced.
