llvm dev - Oct 2017 - Adding comments to LLVM IR during code generation

Hello all,

this is "frivolous", and I understand that there are good reasons as
to why
the IR representation does not have a representation for comments (unless I
am mistaken).

However, I would really like to have the ability to generate comments along
with LLVM IR from my compiler backend.

It would greatly help in debugging LLVM.

Since I cannot generate comments, what alternatives to I have to allow me
to quickly add info the the IR that is easy to scan over?

Cheers,
~Siddhart.

Today, you can use inline asm with side effects to emit comments bracketing
the code you care about. Of course, optimizations will move instructions
past these markers as normal, but presumably that's working as intended.
