[LLVMdev] Question about TableGen when adding LLVM Backend.

LLVM can be built using either CMake or the GNU Autotools. Your backend
ought to provide support for both build systems, so you should create a
CMakeLists.txt as well as a Makefile in your sub-directory.
The Makefile appears to be rather trivial because there's some automagic
going on - nevertheless, you will need one. :-)

> Or is that optional when you just invoke "make"?
In that case you're using the Autotools, so your Makefile is going to be
utilized.

Best regards,
