#Decompyle incomplete on terminal python 3.9
Unsupported opcode: RERAISE

I hope someone solves this there is no decompile tool that can decompile python 3.9 yet

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!

after rebuild,Try to decompile, the program reports an error

yes,it work, I change ASTree.cpp(1158line) as following:
case Pyc::JUMP_IF_FALSE_A:
case Pyc::JUMP_IF_TRUE_A:
case Pyc::JUMP_IF_FALSE_OR_POP_A:
case Pyc::JUMP_IF_TRUE_OR_POP_A:

case Pyc::INSTRUMENTED_POP_JUMP_IF_FALSE_A:
case Pyc::INSTRUMENTED_POP_JUMP_IF_TRUE_A:
case Pyc::RERAISE: //raymond ren
case Pyc::CALL_FUNCTION_EX_A:
case Pyc::JUMP_IF_NOT_EXC_MATCH_A:
{
PycRef cond = stack.top();
PycRef ifblk;
int popped = ASTCondBlock::UNINITED;
