[swift-dev] Create SILType from GenericTypeParamType

[Slava Pestov]

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.

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?
