* DESCRIPTION
* These routines take the parse tree and pick out the
/*-------------
- * Interpret the parameters *parameters and return their contents as
- * *byte_pct_p, etc.
+ * Interpret the parameters *parameters and return their contents via
+ * out parameters *isStrict_p and *volatility_p.
*
* These parameters supply optional information about a function.
- * All have defaults if not specified.
- *
- * Note: currently, only two of these parameters actually do anything:
+ * All have defaults if not specified. Parameters:
*
* * isStrict means the function should not be called when any NULL
* inputs are present; instead a NULL result value should be assumed.
*
* * volatility tells the optimizer whether the function's result can
* be assumed to be repeatable over multiple evaluations.
- *
- * The other four parameters are not used anywhere. They used to be
- * used in the "expensive functions" optimizer, but that's been dead code
- * for a long time.
