Name

normExpr - normalizes an expression

Synopsys

#include logmmm.h"
void normExpr(expr)
chain_list *expr;

Parameter

expr
expression to normalize

Description

normExpr() sorts recursively the arguments of an expression by using predefined rules. The operator expressions are sorted by increasing operator number and arity of the first level. The atomic expressions are put at the end of the operator expressions.

Example

#include mutnnn.h
/* mbk utilities */ #include logmmm.h" chain_list *expr1;

/* let's suppose that expr1 = (AND a (XOR b c a) (NOT h) (AND e g) (OR b a)) */

normExpr(expr1);
displayExpr(expr1);

/* it will display
(AND (OR b a) (AND e g) (XOR b c a) (NOT h) a) */
freeExpr(expr1);
