[LLVMdev] llvm-mc standalone assemblers and testing

[Carter, Jack]

We are already generating object directly.

It is on my roadmap to implement the standalone assembler, but I was hoping for some suggestions ;-)

My target is Mips and I have started looking at what ARM does. If there is a better model or how-to guide I'd like to know.

Thanks,

Jack

I have had references to llvm-mc in terms of a tester for MC level code changes and have just found and read the blog http://blog.llvm.org/2010/04/intro-to-llvm-mc-project.html.

Am I correct that lib/Target/<target>/AsmParser/*.cpp needs to be completed to make a standalone assembler for a specific target and until that is done, llvm-mc can't be used to generate output object that is tested by elf-dump?

You need to implement an AsmParser if you want to generate object files from assembly files.  You can generate object files from higher-level inputs (.c, .ll) without a functional AsmParser as long as your inputs don't use inline assembly.
