◆ isFuncParamTypeConvertible()

bool CIRGenTypes::isFuncParamTypeConvertible ( clang::QualType type )

Return true if the specified type in a function parameter or result position can be converted to a CIR type at this point.

This boils down to being whether it is complete, as well as whether we've temporarily deferred expanding the type because we're in a recursive context.

◆ isFuncTypeConvertible()

bool CIRGenTypes::isFuncTypeConvertible ( const clang::FunctionType * ft )

Utility to check whether a function type can be converted to a CIR type (i.e.

Code to verify a given function type is complete, i.e.

doesn't depend on an incomplete tag type).

the return type and all of the parameter types are complete. Also check to see if we are in a RS_StructPointer context, and if so whether any struct types have been pended. If so, we don't want to ask the ABI lowering code to handle a type that cannot be converted to a CIR type.
