Hope you're doing well. <br>

It seems to me that it is not possible to extend the current behavior of `llvm::SourceMgr` (at least I couldn't think of any solution) and it is quite C/C++ish ( for lack of a better word).<br>
<br>
For my use case, I need to tweak it a little bit and since there is now way to do that, I have to write my own which means I'm going to lose the ability to use any llvm api that expect a source manager and that's a big price to pay.<br>
<br>
It seems that the source manger will benefits from a trait like design. This way, any front end that need a customized source manager can easily do that and the current source manager would be an implementation of that trait.<br></blockquote><div><br>I /think/ the C++ terminology that's a closer match for what you're describing might be a "concept" rather than a "trait"?<br><br>But then, if I'm understanding correctly, all the code that currently is written in terms of the SourceMgr would have to become a template so it can be used by different implementations of the SourceMgr concept? That, at first guess, seems unlikely/infeasible?<br><br></div><div> - Dave</div></div></div>
