Hi,
I’m getting the following error when I’m trying to compile/link llvm with a backend I have. Running make on the /lib/M68K directory ends without any errors, and I have made all the required files and functions as outlined in http://llvm.org/releases/2.5/docs/WritingAnLLVMBackend.html
I copied most of the files from Sparc backend and remove the content from functions mostly. Anyone has seen this error before?
