[llvm-dev] Need help with code generation

[Lorenzo Laneve via llvm-dev]

I'd like to make my compiler independent, just like Clang. Doesn't Clang call llc and then system's ld by itself? I don't want my compiler to depend by any other program.
I guess there will be a class in the llvm library that generates the object files based on the system's triple and data layout, and then call the system's ld?
