<div>I
cannot find any way to do that, nor the RefactoringTool, nor the
Rewriter classes seem to expose any functionality at all to write the modified files anywhere else. How should I go about this (without modifying clang itself)?<br></div>

<div>I need to specifically write out the modified files.<br></div>

<div>Unfortunately, I do, because I work in an environment where we cannot compile using clang, only GCC. The reasons for this are... interesting, at best, but unfortunately this is what I have to work. I agree with you though, IR-level instrumentation is obviously a much better idea... one that's not feasible in my situation.<br></div>

<div>Do you need to instrument the /source code/ in particular? The usual approach with other instrumentation (sanitizers, code coverage, etc) is just to instrument the resulting binary (by instrumenting the LLVM IR generated by the frontend - usually during IR generation in the frontend (Clang, most often)) rather than mutating the source (or generating a mutated copy of the source) & then compiling that.<br></div>
<div> </div>
<div>The refactoring tools are really focussed on the scenario of refactoring - where you actually want to modify the original source. (not that they can't be used for other things, just that they might not be the best tool for the job)<br></div>
