Block has been patched???

[simhigo]

When I run ""deflatten_cfg(bv, pw, 0x0034ff78, 0x0034d9b4)"", I get an error message "Block has been pathced"
Can you help me with what is the problem?

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

[simhigo]

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.

[simhigo]

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.

[simhigo]

i have a one more issue.

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?

[amimo]

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.

[simhigo]

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