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 is a simple-minded script to compare the functions and instructions
|
|
# listed for two different models in one or more .igen files.
|
|
#
|
|
# It was intended to be useful to help factor models into common subsets.
|
|
#
|
|
# Things to note:
|
|
#
|
|
# * igen include directives are not processed!
|
|
#
|
|
# * functions and instructions with multiple definitions (e.g., based
|
|
# on model names) are treated as being different. In other words,
|
|
# if two models have different functions named 'foo', this
|
|
# script will say that one has one of the function definitions, and
|
|
# the other has the other.
