TypeTuple toArgTypes(Type t);

This breaks a type down into 'simpler' types that can be passed to a function in registers, and returned in registers. It's highly platform dependent.

Parameters:

Type t type to break down

Returns:

tuple of types, each element can be passed in a register. A tuple of zero length means the type cannot be passed/returned in registers. null indicates a void.
