SYNOPSYS¶

#include "abl101.h"
chain_list *createablxorbinexpr( Oper, Expr1, Expr2 )


  long        Oper;


  chain_list ∗Expr1;


  chain_list ∗Expr2;

PARAMETERS¶

Oper

Operator ABL_XOR or ABL_NXOR.

Expr1

First expression.

Expr2

Second expression.

DESCRIPTION¶

createablxorbinexpr creates a binary 'xor' or 'xnor' operator expression with the 'and', 'or' form. createablbinexpr simplifies eventually the sub-expressions. The expression pointers Expr1 and Expr2 MUSTN'T be used after the call to this function.

RETURN VALUE¶

createablxorbinexpr returns a pointer to the new operator expression.

ERRORS¶

"ablcreate: bad operator xx !",

EXAMPLE¶

#include "abl101.h"


   chain_list ∗ExprA;


   chain_list ∗ExprB;


   chain_list ∗ExprAxorB;


   ExprA = createablatom( "a" );


   ExprB = createablatom( "b" );


   ExprAxorB  = createablxorbinexpr( ABL_XOR, ExprA, ExprB );


   /* displays (a and (not b) or (b and (not a)) */


   viewablexpr( ExprAxorB, ABL_VIEW_VHDL );
