patch to add setAuxTarget call to ASTUnit::Parse
I'm using libclang to parse CUDA sources via clang_parseTranslationUnit2, which
ends up calling ASTUnit::Parse. Unlike CompilerInstance::ExecuteAction
ASTUnit::Parse does not call setAuxTarget for the secondary target for CUDA
compilation. This results in several undeclared __builtin_ptx_* errors. Adding
the call resolves this.
Attached is a small patch for ASTUnit::Parse.
There are several other callers of CompilerInstance::setTarget (mostly in
ASTUnit.cpp) that don't call setAuxTarget either. Maybe the
setTarget/setAuxTarget call pair could be factored out into some sort of
setAllTargets call that all callers could use.
I don't know enough about the codebase to restructure this properly, though.</pre>
