[cfe-dev] Multiple plug-ins in one shared lib?

[Jordy Rose]

Hi, Erik. AFAIK it's not yet possible to run multiple plugin actions from a single invocation of clang. This has nothing to do with where the actions come from; it's just how -plugin is handled.

Please file a bug at http://llvm.org/bugs with your expected behavior: do you want the plugins to be run serially on the original AST, or should they be able to return a new AST so they can act as filters of some kind, or...

(my guess is you just want the first one, but I thought I'd bring it up)
