[llvm-dev] Potential ambiguity in the grammar of LLVM IR assembly

[Robin Eklind via llvm-dev]

Hello Manuel,

Thank you so much for bringing this to my attention. I wholeheartedly 
agree that the grammar is simplified by this change and welcome it with 
open arms.

Credit goes to Rafael for pushing this work.

This would indeed remove the language ambiguity as far as I'm aware.

Kindly
