If it doesn't make a difference, then remove that part of the condition clause? If you object to doing that, then the overflow seems like an issue. > Plus inside a plugin, I don't see why you care about if -frandom-seed was > supplied or not. So that I can decide whether I am allowed to do things totally randomly or if I must follow some sort of seeded determinism. The broader answer is of course, "because plugins can do many things." > You mean toplev.cc right? I guess I'm reading gcc 11 source code, but yea, sure, same difference.
