Looking for a way to find duplicate subroutines.

[Ximonite]

I am wondering if there is any easy way to find duplicate subroutines in a PE file. I initially tried using a hex editor, but found that calls would make it not work because of the fact that the hex data may vary even when calling the same function or subroutine. An IDA plugin would be ideal, but I am fine using anything that does the job.
