[LLVMdev] llvm-mc and endianess.

[Dominique Torette]

Hi,

As a first step to port the LLVM chain on an in-house big-endian processor, I'm integrating the native assembler as a new '-assemble -arch=' in llvm-mc.
All work quite well, I have a correct output ELF format except that generated code is little-endian.
I've understood that the endianess of the LLVM chain is controlled by the DataLayout class, but it appear to me that llvm-mc does not make use of  such class.
I've seen a backend (CPU0, http://jonathan2251.github.io/lbd/genobj.html) that defines two different targets and performs the byte swapping as part of the 'EmitInstruction'. Is it the right way?
Could somebody confirm my understanding and give me some tips about endianess in llvm-mc?

Thanks,                Dominique T.
