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

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