# The purpose of this script is to provide a large amount of IR/bytecode from a known
# application to be diffed against the same output with a different Nashorn version.
# That way we can quickly detect if a seemingly minute change modifies a lot of code,
# which it most likely shouldn't. One example of this was when AccessSpecializer was
# moved into Lower the first time, it worked fine, but as a lot of Scope information
# at the time was finalized further down the code pipeline it did a lot fewer callsite
# specializations. This would have been immediately detected with a before and after 
# diff using the output from this script.
