hi there, i´m using last version of bison on windows xp., bison 1.875
i have come up with a problem which is just dirving my crazy, see the code here:
function_designator : identifier {
dir=BuscarSimb(TablaActual,$1,&veces);
$$=malloc(sizeof(struct RecordGCI));
$$->tipo=dir->tipo;
$$->texto=malloc(strlen($1)+1);
$$->texto=strcpy($$->texto,$1);
$$->tiporet=dir->tipo_retorno;
$$->numparam=dir->n_param;
strcpy(nomfungu,$1);
nodolistaauxiliar.paramlleva=numparamllevo;
nodolistaauxiliar.parammax=numparamreal;
nodolistaauxiliar.sigparam=puntiparam;
nodolistaauxiliar.ptrbu=$$;
strcpy(nodolistaauxiliar.nomfun,nomfungu);
Insert1(nodolistaauxiliar,listaauxiliar);
numparamllevo=0;
CuantosNormal++;
FunDesigIden();
}
params {
FunDesigParams($$);
};
ok, so the big problem is that after params , when calling FunDesigParams($$),
the pointer has changed its value but i can assure you that i do not
touch that $$ any other place but here, and still do not change it at
that Macro(fundesigparams)
i know it has changed cause i have aprintf which i did not copy here,
a printf just after the malloc and another one just before FunDesig.
the union is this:
%union {
int numero; /*Valor numerico */
char * texto; /*Valor del lexema o la cadena de texto*/
char t; /*Tipo de expresion E.tipo*/
char op; /*Que operador (Si procede)*/
int tipo; /*Si es identificador, enterlo literal, true o false.*/
int v_ent; /*Valores de los enteros*/
int v_bool; /*Valores de los booleanos*/
char* v_cad;
struct TNodoSim* p_id;
struct RecordGCI* semix;
};
and the type for func desig is:
%type <semix> function_designator
can anyone plz help me? i m just gettin crazy!
