oh_path_functions is only used to stimulate short range functions for the GDB patcher. NOP all the instructions in it, once GDB patcher is done.

@anahitH I was not able to fully test this as the transformed bc (with short range protection) cannot be executed anymore. I used tetris as my example. Any ideas?

@mr-ma What is the reason of patched binary not running? Is it crash or something else?

I've tested your changes on testris and it works for me. oh_path_functions' content is nop-ed in the final binary and it runs without any problem.
