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. |

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. |

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. |

Added supposedly improved exception handling in order to use Python VM
features. The problem is that the JVM athrow instruction is dynamic and
best translates to the Python VM RAISE_VARARGS instruction. However, in
order to support RAISE_VARARGS, the SETUP_EXCEPT, SETUP_FINALLY, POP_BLOCK
and END_FINALLY instructions are also required, yet the JVM supports try...
catch...finally (whereas the Python VM only supports try...except and
try...finally), and anticipates finally handling using very low-level
subroutine calling and arcane usage of local variables.
Changed the result of the translate convenience function and the parameter
specification of the translate and disassemble functions.
Fixed the get_value method in LazySubValue and the LazyValue portion of the
_write_value method in BytecodeWriter. |
