Get size of a native function

[ltfish]

I don't think we have that interface in angr right now.

One thing you can do, is adding up sizes of all basic blocks inside a function, and subtract the duplicate parts.

I'm running out of cycles for the next three days. Maybe someone else in the team has time to implement this feature - or we are happy to take your contribution :-)

This is a value exported by the elf symbols, if they are present! If your binary is not stripped, the symbol with your function's name, accessible through CLE, has an attribute size or sh_size or something that gives you the size of the function, if memory serves.

In the case of stripped binaries, you will need to do something similar to what ltfish described. Somehow using a normalized CFG (what's the interface for that, I forget?) will help you avoid the duplicate parts thing.

Thanks! Both of them worked.

Opened a relates issue: angr/cle#6. Please have a look.
