[LLVMdev] Frontend: How to use Member to Function Pointer as callbacks
...also not have to embed/use LLVM at runtime, just like a plain
C/C++ executable).
One (rather complicated) option I was thinking is:
- Define a maximum number of those callback alive (let's say 4096) -- it's
not per function signature, but global
- Define i8* thunkTargets[4096]
- Define i8* ThunkIdToFuncPtr[4096]
- Define 4096 funcs (not even sure how to do that with LLVM, might need to
emit assembly?)
Thunk0: jmp thunkTargets[0];
Thunk1: jmp thunkTargets[1];
...
Thunk4095: jmp thunkTargets[4095];
- When I call a C function from C# with a callback, what happens is:
- Find an unused...
