llvm-dis: Invalid record

[wezhousheng]

I've used the method you introduced and get files from .xar file. Finally use llvm-dis, but i get such error of llvm-dis: Invalid record. It's may be the wrong format of the bitcode file. Any suggestion?

Hi and sorry for the long delay.
Just checked my example (make subject) and the format seems to be fine. The only reason I see: llvm we have (open source version) doesn't support some records from llvm/clang provided by Apple (e.g. some swift specific stuff).

Now that Apple has open sourced LLVM, you might have more luck with llvm-dis from the swift llvm fork.

@praseodym thank you, this is very valid point. I'll take a look
