We have modified Bison to produce a hard-coded (directly executable)
LALR parser. We are currently looking for grammars that we can use to
test our generated parsers for speed.

Specifically we are looking for yacc/bison grammars that have been
stripped of semantic actions, the grammar should also include a test
suite that we can use to measure parsing speed. Even better would be a
grammar that had input files as lists of tokens that we could feed to
the parser to avoid lex overhead.

We are also interested in any compiler that uses yacc/bison grammar
specifications along with the rest of the compiler system. This would
give use the opportunity to measure the overhead involved in parsing a
variety of languages.

Completely unrelated aside: We looked at GCC, the parser is implemented
as a yacc/bison specification, unfortunately the semantic action have
deep hooks into the internals of the generated yacc/bison code.

A preliminary report of our work can be found at:

If you have such a grammar or know of one please send email to
