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

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