How can I bypass dependency builds while building my clang plugin?

Question

Is it possible to build a clang plugin using an already built version of clang?

I've done all the steps to download and build clang but I don't know how to set up a tool so that the Makefile doesn't traverse the entire llvm and clang directories each time that I compile my tool (traversing the Makefile seems to take about as long as building my single file plugin).

Thanks.

If you are using the CMake build system (which you should be with reset LLVM), then CMake creates special targets to bypass dependency checks.

If you target name is target, call:

make target/fast

And then the Makefile will not check/rebuild all the dependent libraries. There is also a make install/fast.

It's quite difficult to find this information online if you don't know about it. – Matthieu Brucher Dec 18 '18 at 17:19
