Unsupported opcodes JUMP_IF_NOT_EXC_MATCH and DICT_MERGE
Should we expect support for opcodes JUMP_IF_NOT_EXC_MATCH and DICT_MERGE in the near future?
I also had a similar error last night, when I tried to decompile the pyc file compiled with python 3.10, the message "Unsupported opcode: BLA_BLA_BLA" appears.
I think this is an error because the pyc file that will be decoded is a bytecode file compiled with python 3.9 and above, and the opcodes that are not supported by pycdc are opcodes that just appeared in python version 3.9 and above.
so I tried reading the ASTree.cpp file and studying it, then I realized that the opcode that was printed as an error was not in the "case block" of the ASTree.cpp file.
I tried to change it a little by adding the opcodes printed in the error message into the case block (on line 1166)
case Pyc::JUMP_IF_NOT_EXC_MATCH_A:
case Pyc::RERAISE_A:
then rebuild it. I don't know what happened but it solved my problem when trying to decompile python 3.9 and above bytecode. everything is done!
@karjok wow, i have to try it!
I have change the ASTree.cpp file as above, eg. add case Pyc::JUMP_IF_NOT_EXC_MATCH_A:
and case Pyc::RERAISE_A:
. But I get the error message "Unsupported opcode: RERAISE". What can I do? If you know why, please notify me, thanks. @karjok
I change the ASTree.cpp but still get the error Unsupported opcode: JUMP_IF_NOT_EXC_MATCH, do you have the a sample file? @karjok, thanks for the help that you can give me
I have a new error, after advance with the code of ASTree, i get:
# Source Generated with Decompyle++
# File: conversorexcelZP.pyc (Python 3.9)
Segmentation fault
Any recommendation?
I can fix it now thanks
