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 !",
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 );
