/* The parser tables consist of these tables. |
|
|
|
|
|
YYTRANSLATE = vector mapping yylex's token numbers into bison's |
|
|
token numbers. |
|
|
|
|
|
YYTNAME = vector of string-names indexed by bison token number. |
|
|
|
|
|
YYTOKNUM = vector of yylex token numbers corresponding to entries |
|
|
in YYTNAME. |
|
|
|
|
|
YYRLINE = vector of line-numbers of all rules. For yydebug |
|
|
printouts. |
|
|
|
|
|
YYRHS = vector of items of all rules. This is exactly what RITEMS |
|
|
contains. For yydebug and for semantic parser. |
|
|
|
|
|
YYPRHS[R] = index in YYRHS of first item for rule R. |
|
|
|
|
|
YYR1[R] = symbol number of symbol that rule R derives. |
|
|
|
|
|
YYR2[R] = number of symbols composing right hand side of rule R. |
|
|
|
|
|
YYSTOS[S] = the symbol number of the symbol that leads to state S. |
|
|
|
|
|
YYDEFACT[S] = default rule to reduce with in state s, when YYTABLE |
|
|
doesn't specify something else to do. Zero means the default is an |
|
|
error. |
|
|
|
|
|
YYDEFGOTO[I] = default state to go to after a reduction of a rule |
|
|
that generates variable NTOKENS + I, except when YYTABLE specifies |
|
|
something else to do. |
|
|
|
|
|
YYPACT[S] = index in YYTABLE of the portion describing state S. |
|
|
The lookahead token's type is used to index that portion to find |
|
|
out what to do. |
|
|
|
|
|
If the value in YYTABLE is positive, we shift the token and go to |
|
|
that state. |
|
|
|
|
|
If the value is negative, it is minus a rule number to reduce by. |
|
|
|
|
|
If the value is zero, the default action from YYDEFACT[S] is used. |
|
|
|
|
|
YYPGOTO[I] = the index in YYTABLE of the portion describing what to |
|
|
do after reducing a rule that derives variable I + NTOKENS. This |
|
|
portion is indexed by the parser state number, S, as of before the |
|
|
text for this nonterminal was read. The value from YYTABLE is the |
|
|
state to go to if the corresponding value in YYCHECK is S. |
|
|
|
|
|
YYTABLE = a vector filled with portions for different uses, found |
|
|
via YYPACT and YYPGOTO. |
|
|
|
|
|
YYCHECK = a vector indexed in parallel with YYTABLE. It indicates, |
|
|
in a roundabout way, the bounds of the portion you are trying to |
|
|
examine. |
|
|
|
|
|
Suppose that the portion of YYTABLE starts at index P and the index |
|
|
to be examined within the portion is I. Then if YYCHECK[P+I] != I, |
|
|
I is outside the bounds of what is actually allocated, and the |
|
|
default (from YYDEFACT or YYDEFGOTO) should be used. Otherwise, |
|
|
YYTABLE[P+I] should be used. |
|
|
|
|
|
YYFINAL = the state number of the termination state. YYFLAG = most |
|
|
negative short int. Used to flag ?? */ |
