Estimated hours taken: 2 Branches: main Runtime fixes for the Java back-end. java/runtime/DuExistLocn.java: java/runtime/DuFunctorDesc.java: java/runtime/DuPtagLayout.java: Define constructors for these types. java/runtime/MaybeResAddrFunctorDesc.java: New file (corresponds to MR_MaybeResAddrFunctorDesc type in C). java/runtime/MaybeResFunctorDesc.java: New file (corresponds to MR_MaybeResFunctorDesc type in C). java/runtime/PseudoTypeInfo.java: Define constructors. Make non-abstract (XXX temp work-around only). java/runtime/TypeCtorInfo_Struct.java: XXX Pass some parameters of the constructor as "Object", to work around type errors in invocations of those constructors. java/runtime/TypeFunctors.java: java/runtime/TypeLayout.java: Model the C unions better; use a single field, with accessor functions that convert to each alternative, not several fields. java/runtime/TypeclassInfo.java: Implement as stub (previous code was just copy of TypeInfo.java). java/runtime/VA_PseudoTypeInfo_Struct*.java: Fix a bug: change the order of the constructor parameters to match the way we generate code which invokes those constructors.
