Added support for the following
POP_JUMP_IF_NOT_NONE
POP_JUMP_IF_NONE
CALL_INTRINSIC_1 (only INTRINSIC_IMPORT_STAR)

patch.txt

EDIT: Fixed logging for unsupported intrinsic_1

I have no idea how to implement the other intrinsics, I found no obvious mapping to prior opcodes like with IMPORT_STAR and since I have no code to test it against either, this is all I can do rn. The script I wanted decompiled is successfully decompiled now, so thanks a lot for this project!

Warning: In my test file, it seems it's inverted - POP_JUMP_IF_NOT_NONE_A needed to be come if xxx is None: for the decompiled behaviour to match the original. No occurences of POP_JUMP_IF_NONE_A to double-check sadly. Not sure if this is a general error, cpython seems to treat POP_JUMP_IF_NOT_NONE_A as expected, and the opcodes also match the ones found here.
This will need proper verification.

pycdc crashes for some pyc files when parsing JUMP_BACKWARD_A(140) in python 3.11, could you examine what the error is?

JUMP_BACKWARD is still not in main branch, you could try to play with this PR: #472

Thanks for the pr!

Anything new about LOAD_FAST_AND_CLEAR?

JUMP_BACKWARD

JUMP_BACKWARD_A与JUMP_BACKWARD是否有区别

POP_JUMP_IF_NONE

合并后依旧报错Unsupported opcode: POP_JUMP_IF_NONE (239)
