Port the class field pointer hell to self-hosted #462

Open Akuli opened 6 months ago

Akuli commented 6 months ago

Pointers in classes are always i8* in LLVM IR, so that a class can contain a pointer to itself. This way you can implement a linked list, for example. Previously this wasn't done in self-hosted compiler.

Extracted from #454.

Something weird happens with booleans on Windows if optimizations are enabled when compiling the self-hosted compiler. It ends up getting a boolean foo that behaves so that foo as int evaluates to 255, not 0 or 1 as expected. Also, if ... or foo does not run when this happens.

This will take a while to minimize into something small, so I can make a bug report / question to LLVM. It is difficult, because the self-hosted compiler is creating bool 255, and it is a lot of code.
