Hi
Normally an LALR(1) algorithm described in text books relies on the
three tables:
-- two dimensional
tables: action(states, terminal) and goto(states, non-terminal)
-- a one-dimentional table rhs_length[rules], the length of the right side of a
rule
However
in bison, every table is one dimendionsal. Could anyone point to me any
reference on the table encoding scheme used in bison, i.e., how to interpreter
those yydefgoto[], yypact[], yypgoto[] etc.?
Thanks
