( https://gem5-review.googlesource.com/c/public/gem5/+/71019?usp=email ) Change subject: arch: set multiline re as default in isa_parser ...................................................................... arch: set multiline re as default in isa_parser In python3.11, it requires the global specifier should be the first token of regex. However it's not possible when using ply library. Instead, we set the rules are multiline regex by default and modifies those single line rules.
