[cfe-dev] preventing clang tool working on same file multiple times

[spsaxena via cfe-dev]

Thanks for your response.

No, I haven't tried emitting replacements from tool and then running
clang-apply-replacement over it. Though I was trying to create a set of all
replacements.
Also seems I cannot try now, based on other response this workflow got some
bug.

Anyway, now what I think is such approach may be time taking as tool will
still need to process same files multiple times, just that the replacement
will be written/executed only once. So for a large number of files it may
take very long. right?

Btw, I am not blocked now, I followed the clang-tidy run script to run tool
on every file.

Regards,
