2.0.4 IDA 'Discovery' Script: Anyone fancy writing

Parent: http://magiclantern.wikia.com/wiki/2.0.4_AJ

===Your camera needs you #1 (and so do I!) ===

Would someone like to hack together an IDA script?

What I am looking for is simple script to AUTO name them if there is a comment in the subroutine.
There are about 15,000 unnamed ones ... this will save me a Huge amount of time.

Details below. If you need incentive ... I'll post you a Beer! (or one of the random alcoholic bevages hiding in my drinks cabinet)

'Script 1:  Naming of 'sub_' routines' using debug comments

Most of the names that I populating are found by looking at the comments in IDA.
I find a undefined subroutine name, I scroll down the subroutine, and I used the first string - and use it:

-------------------------------------
FF98D7BC sub_FF987DBC
........
FF98D7E8      ADR R2, aH264rapperPout ; "[H264Rapper] pOutputAddress=0x%08X"
-------------------------------------

Would become:

-------------------------------------
FF98D7BC AUTO_'H264Rapper_pOutputAddress'
........
FF98D7E8      ADR R2, aH264rapperPout ; "[H264Rapper] pOutputAddress=0x%08X"
-------------------------------------

If there are No comments in the subroutine - then do nothing.

Thanks :)

    MakeName(Dword(i+4), GetString(Dword(i), -1, ASCSTR_C));
  }
}

a first step for your script

[AJ] Thanks for taking a shot at that AI ... maybe I could send you 'shot of something :)
