there might be bugs in the "delete_overlap_edges" function, you can start there.

I tried changing the address
"deflatten_cfg(bv, pw, 0x0034d99c, 0x0034d9bc)"

it was not optimized.

does this script produce some log like:"patch branch address xxx".If so, try to re-analyze this function after running the fix-xxx.py script in ida.

This is the result from the completion of re-analyze & function tell edit after running the fix-.py script.

hellojni_3.0.3.zip
block 0x001582bc in function 0x1494c4 at libhello-jni.so may be your case. run the script in the attachment, see how it is handled.
ps: it may take ida hours( > 12h) to re-analyze this function.

In my opinion, it seems to be a different case from the one you delivered.

It is a new code case.

When setting the code range for the case as below, an error message occurred.

Can you help me with what is the problem?

Those two addresses are not code range.
The first one is the address of a state var definition in mlil view, the second is the address of the
corresponding dispatcher.

Those two addresses are code segment.
This binary is dylib
Is there any support for dylib?
