[cfe-dev] RefactoringTool - set output file path?

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)?

I need to specifically write out the modified files.

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.
