<div dir="ltr">So to give more context to the question, I have a match that is generated on the header file and I'm trying to jump to the mapped .cc file that actually defines that class. I'm pretty new to clang development so I might not be doing this the best way, but I have a custom ASTFrontendAction for matching the header file pattern that I have defined that then calls a custom subclassed MatchFinder::MatchCallback. <div>
<br></div><div>I will try using runToolOnCode and define a new FrontEndAction for the operation that I will run on the cc file. Is there also an easy way to convert an llvm::MemoryBuffer to a Twine? I noticed runToolOnCode requires a Twine, not a MemoryBuffer. I was thinking of doing MemoryBuffer::getBuffer() and constructing a Twine out of this, but is there a simpler way?<br>

I don't think that FileManager and SourceManager will magically parse your file, you can obtain FileEntry but that's just a low level class that wraps some file system stuff... I think that you need to do the same thing you're doing with your header file, how are you feeding that into RecurisiveASTVisitor? clang::tooling::runToolOnCode seems to be the way to go, you just need to pass it the contents of your .cc file. You might be able to get it by calling SourceManager::getMemoryBufferForFile, but I'm not sure if you have to use clang's infrastucture for this at all.<div>
