#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 !",
Operator must be ABL_XOR or ABL_NXOR.

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 );
