 I'm trying to understand the file parse.output
produced by bison when given parse.y from gcc. One is referred to literature
on yacc for bison, but there are some differences between yacc and bison.
One difference is the format of the .output produced when bison is called with
the -v flag. The format of the .output file for yacc is explained a little
in the book Introduction to Compiler Construction With UNIX, by Alex Schreiner
and H. George Friedman, Jr. But the format in the case of bison is different
and I don't know what it means. Another difference between yacc and bison is
that bison allows semantic parsing, via the file bison.hairy and as far as
I know there is no comparable feature in yacc. Therefore, semantic parsing
with bison is entirely undocumented.  How is one supposed to learn it ?
