Dear all, I am looking to output assembly comments in my emitPrologue() function, just for my own readability. Searching for a way to do this found me this thread - http://lists.cs.uiuc.edu/pipermail/llvmdev/2011-October/043722.html, which says that the best way to output comments from somewhere like emitPrologue() is to: 1. Create an MDString for the comment. 2. Attach it to an LLVM

Seems llvm cannot pass metadata to MachineInstr, or setting operand description in class Instruction and pass to class MachineInstr. Is it a good idea to extend llvm kernel structure to having this feature?
