Hi LLVM and CLang Devs, At the moment my company (Movidius) is considering contributing the changes we have made to LLVM and CLang in order to support our proprietary processor, and I would like to seek advice on how best to approach doing this? I am pretty sure that there are coding guidelines and conventions that we should be following but have not foll...

Hi LLVM-Dev, I have just integrated the changes from top-of-tree at SVN #262824 (yesterday) having been previously at #262217 (a week ago). I am getting the following error for every instruction: CUSTOMBUILD : error : No schedule information for instruction 'FOOBAR' What has changed that would cause this and how can I fix it in my target? Thanks, MartinO

...but I don't have an instruction called COPY (this is a target-independent default). I also tried adding: let CompleteModel = 0; to my base instruction type, but it is unrecognised.

At the moment I am using LLVM to target our proprietary SHAVE processor, but the Movidius "Myriad" chip also utilises a Sparc Leon for executive functions. For this I use the GCC compiler. This all works fine, but I would like to consolidate code generation for both targets in the same LLVM derived compiler to simplify things and I have a couple of questions about the Spa...
