llvm dev - Jan 2014 - [LLVMdev] How to print a list of used LLVM APIs in a given open source project?

Hi,

     Assume there's an open source compiler implementation based on
LLVM/Clang. What is the neatest way to print a list of LLVM APIs used in that
open source project? Thanks.

Best,
Jiading

As a first approximation, you can scan #includes in the project or look for
`llvm::[a-zA-Z0-9_]+`. If you need something precise, you could try using
Clang's ASTMatcher's to query for all referenced declarations in
namespace
`::llvm`.

I have not tried that tool (yet) so this is speculative.

But from the docs it appears to me that Google's include-what-you-use 
could help.
See the output described here: 
http://sylvestre.ledru.info/blog/2013/09/08/include-what-you-use-yet

You could do a temporary run. Not to "fix" your includes, but just to 
get a list of all the
#include + reference statements printed.

Cheers,
Jonas
