llvm dev - May 2013 - [LLVMdev] How to associate extra comments to a MachineInstruction ?

Hi,

is there a convenient way to associate/add a comment to a  MachineInstruction,
so that
in the produced assembly file, the comment is added next to the instruction ?

Greetings,

Jeroen Dobbelaere

Should be spelled like this yes?

Asm->OutStreamer.AddComment("foo")
Asm->EmitFoo();

That  should work at the moment that you are emitting the instructions.

But what would you do when you are manipulating a MachineBasicBlock and want to
annotate some instructions there ? (way before the assembler jumps in)
The annotation belongs to the instruction and other manipulations that are
performed later (like reordering of instructions)
should keep the annotation (iff the instruction itself is kept).
