gen-evolution.awk is explicitly blacklisted:
self.skip_files |= set ([
# Not part of GCC
'math-68881.h',
# Weird ways to compose copyright year
'GmcOptions.cc',
'gen-evolution.awk',
'gen-cxxapi-file.py',
])
and that is due to
if (to_year == "")
print " Copyright (C) " from_year \
" Free Software Foundation, Inc."
else
print " Copyright (C) " from_year "-" to_year \
" Free Software Foundation, Inc."
which contrib/update-copyright.py just can't parse.
Guess we could break it up as
print " Copy" "right (C) " from_year \
" Free Software Foundation, Inc."
or similar.
gen-cxxapi-file.py is similar, it has
print("""%language=C++
%define class-name std_name_hint_lookup
%struct-type
%{{
/* This file is auto-generated by {:s}. */
/* Copyright (C) 2022-{:s} Free Software Foundation, Inc.
...
#""".format(script, time.strftime('%Y')))
So, maybe in that case we could use
/* Copy{:s}right (C) 2022-{:s} Free Software Foundation, Inc.
and
#""".format(script, "", time.strftime('%Y')))
