A while back, in working on a cross-version python decompiler, I used
PyPy's lib_pypy/_marshal.py.
Recently in doing work in writing a cross-platform a Python bytecode
assember, I noticed what is in the py3.5 branch is a bit out of date for
Python 3.
Specifically these types:
TYPE_REF
In looking at Python bytecode over the years, I've noticed that it does
very little to no traditional static-compiler optimization. Specifically:
* Dead code elmination (most of the time)
* Jumps to Jumps or Jumps to the next instruction
* Constant propagation (most of the time)
* Common subexpres
Yes, that's true, but I believe that such decisions should offered to the
programmers rather than dictated. There is also a whole other discussion on
* how/where optimizations/transformations could be recorded
* how tracebacks could be handled
* debugging optimized code
But here I wanted to foc

Hi -
I have a cross-version Python bytecode disassembler xdis (
https://pypi.org/project/xdis/) and I notice that flags 0x0100 and 0x0200
(DONT_IMPLY_DEDENT and SOURCE_IS_UTF8 respectively) conflict in Pypy 3.6
with Python 3.6's ITERABLE_COROUTINE and ASYNC_GENERATOR.
However in pypy3.6-7.2.0, i
