unlinker IDA - an IDA plugin for extracting functions from a PE file for later reuse

[jonwil]

Made some more fixes and jump tables are now supported (go to the end of the function where the jump table is and press "e" to move the function end past the jump table and then when you unlink it will emit the correct data for that jump table)

Doesn't do indirect jump tables yet though.
One limitation though, if you have something like this in IDA
jmp short loc_401220
align 10h
i.e. any case where there is an "align" statement inside a function) you need to go to that statement and press "code" to convert it to code otherwise it wont unlink properly,.
