2004-11-10 Paul Boddie changeset files shortlog graph Reverted the ret instruction's implementation to use return addresses. Introduced finally handler detection to produce END_FINALLY rather than RAISE_VARARGS from athrow instructions. Fixed invokevirtual. Changed new and invokespecial to work better with the Python initialisation model, removing the __java_init__ method. Now, the new instruction yields a class reference which is then used accordingly by invokespecial. However, invokespecial is made aware of whether it is operating within an <init> method, although this may need further examination. Changed the translate, disassemble and BytecodeReader.process signatures to work on methods rather than separate code and exception table objects.

2004-11-09 Paul Boddie changeset files shortlog graph Added a test of try...finally. Note that this exposes issues with revision 1.10 of bytecode.py, since the exception is not re-raised.

2004-11-09 Paul Boddie changeset files shortlog graph Fixed comparison plus branch (if_acmp*) by removing the comparison result from the operand stack. Added stack top duplication before RAISE_VARARGS so that the appropriate handlers can save the value. Changed the value stored in the load_const_ret method so that None is stored (although this may need verifying). When the translated ret instruction (END_FINALLY in the Python VM, again requiring verification) is executed, the value loaded just prior to its execution should be the same as that saved at the beginning of the handler, and this should be None or a raised exception. NOTE: The load_const_ret translation should arguably retrieve the saved NOTE: value from the beginning of any active handler instead of just NOTE: loading None. This may be assured in try...finally constructs NOTE: (without catch sections), however. Rearranged Python VM instruction insertion for exceptions. Changed some load_global(None) usage to load_const(None). Added instruction positions in the disassembly output.

2004-11-09 Paul Boddie changeset files shortlog graph Added local variable usage tracking. Changed the invokespecial implementation, since it probably has very little to do with superclass method invocation specifically. Extended the test program to try and assemble an entire class. Attempted to fix block gymnastics for exceptions.
