Subject: Fixed an optimizer problem: A branch into a list of at least two branches
X-Git-Tag: V2.13.0rc1~348
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=df341b65516fc949a82e6cd2a1c9b4970e82029d;p=cc65

Fixed an optimizer problem: A branch into a list of at least two branches
pointing to themselves caused the optimizer to loop forever.
