However, I'm having some trouble with crashes when I try to follow the guide. <br>
The first section provides a very useful example of what the whole .cpp file should look like for the HelloWorld pass. Obviously it's a bit more complex to write the whole setup with an analysis group, an analysis pass, and a transform pass that uses the analysis, but example code would be extremely helpful, and could serve as a good starting point for anyone who wants to do something similar. Is there anywhere i could find such example code, perhaps as part of a project, that demonstrates how to define and use an analysis group out of tree?<br>
</div></div></div></blockquote><div><br></div></div></div><div>It's not entirely clear which part you're having a problem with. If it's creating an analysis group, there should be samples within the LLVM source code. If it's building out-of-tree, take a look at <a href="https://github.com/eliben/llvm-clang-samples" target="_blank">https://github.com/eliben/llvm-clang-samples</a> -- it's a repository with a bunch of LLVM/Clang samples, all built out of tree. It keeps pretty close track to ToT, as well as having branches for prior releases (3.3 and 3.4, for now).</div>
