Hi,
I am trying to create a new generic function in the Swift compiler (as part
of a pass). Although I am able to create the generic function signature
fairly easily, I do not find an easy way to create a SILType from a
GenericTypeParamType, which is needed to be passed to
createFunctionArgument. Any help/suggestion?
Best,
Raj
There are two things that need to happen here, first the generic type parameter needs to be substituted with a concrete type, then it needs to be “lowered” to a SIL type.
You can try something like this,
GenericTypeParamType *paramTy = …;
SILFunction *F = …;
SILType T = F->getModule().Types.getLoweredType(F->mapTypeIntoContext(paramTy));
But we would need more details to understand what you’re doing.
