I was reading the original paper about Bison - "Static Semantics and

Bison's table
organization is based on a technique proposed by Ziegler and

Tarjan and Yao in [TY78] ("Storing a Sparse Table");
My question is this: does Bison still follow that scheme? I
wouldn't want to
dive into this paper ([TY78]) if you have changed the compression
scheme
during the course of Bison development history.
Earlier versions of Bison, before the days of M4, used to have a
skeleton file called bison.hairy, which derived from Robert Corbett's
thesis. It fell out of use, unsupported, and nobody could get it
running. After suggestions from himself, it was removed.
Also, is there is a simpler explanation of the rationale behind the
tables
being organized in that way (specific to Bison)? I'd want to read
about
that. Thanks!!
According to him, this stuff was dead. But the study of error
recovery techniques continues at Berkley by Susan L. Graham.
You might search the Bison mail list archives for "Corbett" to see
this discussion.
