Adding a new target

Project Infrastructure LLVM Dev List Archives
#1

Dear.

I am trying to register a new backend say Dummy with LLVM. I have added the target to the configure script following the currently registered targets (also done the target registration steps in the docs). On running the ./configure there are no errors. When on doing the make the following error occurs.

llvm-build: error: invalid target to enable: ‘Dummy’ (not in project)

Can anyone point me in the right direction?

Regards,
Pratik

Hi Pratik,

Have you added your target to: /lib/Target/LLVMBuild.txt? It has a list of subdirectories to build.

You may also find it useful to add it to /include/llvm/ADT/Triple.h.

I hope that helps.
