Run clang-extdef-mapping on the .ast files instead of the source
I just wanted to give you guys a heads up that I just landed: https://reviews.llvm.org/D128704 which makes it possible to run clang-extdef-mapping on the ast files directly instead of having to re-parse the source.
This gives a nice 3x speed-up on our codebase. You can see the numbers in the review above.
This will be included in clang 15.x - but you can detect if it's possible by parsing clang-extdef-mapping --help and it will mention ast files there when my patch is running.
This is a great addition. Thanks! We will add this support for this in CodeChecker.
