Yes, the call to `getSpecificModuleCachePath()` (now
`createSpecificModuleCachePath()`) is in
"clang/lib/Frontend/FrontendAction.cpp". There we don't have a `Preprocessor`
or `HeaderSearch` set up yet, since we're only in the process of massaging
`PreprocessorOptions`. This is why we need to compute it ourselves.
The second call is done from `HeaderSearch::initializeModuleCachePath()` which
we call in "clang/lib/Frontend/CompilerInstance.cpp". I think this is indeed
redundant with the first call, but I'm not 100% sure.
I personally don't mind this that much, but if we can find an elegant way to
de-duplicate these calls, that'd be a good follow-up.
