3polygen grammar for LLVM assembly language.
4
5This file defines an LLVM assembly language grammar for polygen,
6which is a tool for generating random text based on a grammar.
7It is strictly syntax-based, and makes no attempt to generate
8IR that is semantically valid. Most of the IR produced doesn't
9pass the Verifier.

23Define rules for non-keyword tokens. This is currently just a bunch
24of hacks. They don't cover many valid forms of tokens, and they also
25generate some invalid forms of tokens. The LLVM parser has custom
26C++ code to lex these; custom C++ code for emitting them would be
27convenient, but polygen doesn't support that.
