Compiler infinitely looping in codegen #724

Closed felixangell closed 8 years ago

felixangell commented 8 years ago

Either that or it hangs, haven't really looked into it. Here's the commit. Basically I accidentally wrote a recursive function, and it's stuck in codegen.

Recursive generic function. I know where it probably happens but I'm not sure I have the willpower to handle more generic issues currently lol

As of 3d064e7 one part of this has been fixed. The rest is a problem with the name mangling. I honestly do not get the interaction between TypeParameter, GenericContext and the mangling, so I'm hoping @MovingtoMars might see something I do not.

18:53:28 kiljacken: i think it's when the type parameter somehow doesn't resolve in the generic context 18:53:34 kiljacken: and then it just returns the old parameter 18:53:53 kiljacken: and then it tries mangling that, fails to resolve, etc
