**
** Invoke a user function (P4 is a pointer to a FuncDef object that

** Register P3 must not be one of the function inputs.
**
** P1 is a 32-bit bitmask indicating whether or not each argument to the 
** function was determined to be constant at compile time. If the first
** argument was constant then bit 0 of P1 is set. This is used to determine
** whether meta data associated with a user function argument using the
** sqlite3_set_auxdata() API may be safely retained until the next
** invocation of this opcode.

/* Opcode: Function P1 P2 P3 P4 P5
** Synopsis: r[P3]=func(r[P2@P5])
**
** Invoke a user function (P4 is a pointer to an sqlite3_context object that
** contains a pointer to the function to be run) with P5 arguments taken
** from register P2 and successors.  The result of the function is stored
** in register P3.  Register P3 must not be one of the function inputs.
**
** P1 is a 32-bit bitmask indicating whether or not each argument to the 
** function was determined to be constant at compile time. If the first
** argument was constant then bit 0 of P1 is set. This is used to determine
** whether meta data associated with a user function argument using the
** sqlite3_set_auxdata() API may be safely retained until the next
** invocation of this opcode.
**
** SQL functions are initially coded as OP_Function0 with P4 pointing
** to a FuncDef object.  But on first evaluation, the P4 operand is
** automatically converted into an sqlite3_context object and the operation
** changed to this OP_Function opcode.  In this way, the initialization of
** the sqlite3_context object occurs only once, rather than once for each
** evaluation of the function.
**
** See also: Function0, AggStep, AggFinal
