@@ -77,6 +77,17 @@ including the separation bw declaration and definition. See for
instance b4_table_define in lalr1.cc. This way, we could even factor
C vs. C++ definitions.
* From lalr1.cc to yacc.c
** Single stack
Merging the three stacks in lalr1.cc simplified the code, prompted for
other improvements and also made it faster (probably because memory
management is performed once instead of three times). I suggest that
we do the same in yacc.c.
** yysyntax_error
In lalr1.cc we invoke it with the translated lookahead (yytoken), and
yacc.c uses yychar. I don't see why.
* Header guards
From Franc,ois: should we keep the directory part in the CPP guard?
