...the problem is the same, all the documention said what the files have to contain but not the details about write them. I need to write a backend for the PIC24, our processor is based on it, so I started analyzing the files for the implementation of the PIC16, all was ok until I analyzed the files PIC16ILowering.cpp and PICInstrInfo.td, this files have defined many things like SDTypeProfile and SDNode and other things I don't have idea from where they come. I mean I tried to find this info from other files, llvm.org and google and no idea. I have checked the documentation, after read it I thought...

Hello Roberto, > Do you have any information I can use for define my new backend? I really > appreciate your attention and any help you can give me. You might want to look into some of the existing backends. Probably MSP430 is the smallest one. Try to examine the history how this backend was added, it was preserved specifically for educational purposes. I must note that it was added 2 years

Hi, I am writing you because I found in the LLVM site you have worked with backends. I am writing a new backend for a processor I am working on, because the compiler that comes with the processor design suite is really messy (it is CoSy). I want to have a power compiler like llvm. I read the "writing an LLVM compiler backend" and I have define almost all the files, but I have problems
