$BOOLEVAL | $B - Boolean expression evaluation mode

boolean-evaluation-directive = ( $BOOLEVAL | $B ) directive-toggle .

Toggles the complete evaluation mode for boolean expressions (that contains boolean OR or AND operators).

If OFF, the generated code stops the expression evaluation as soon as the result is known unambiguously.

When ON, the generated code evaluates all the expression, using a boolean stack to store intermediate sub-expressions values.

• When OFF, side effects may occur if one term is a boolean function call that modifies some context.

Default is ON.
