+** Synopsis: release r[P1@P2] mask P3
+**
+** Release registers from service.  Any content that was in the
+** the registers is unreliable after this opcode completes.
+**
+** The registers released will be the P2 registers starting at P1,
+** except if bit ii of P3 set, then do not release register P1+ii.
+** In other words, P3 is a mask of registers to preserve.
+**
+** Releasing a register clears the Mem.pScopyFrom pointer.  That means
+** that if the content of the released register was set using OP_SCopy,
+** a change to the value of the source register for the OP_SCopy will no longer
+** generate an assertion fault in sqlite3VdbeMemAboutToChange().
+**
+** If P5 is set, then all released registers have their type set
+** to MEM_Undefined so that any subsequent attempt to read the released
+** register (before it is reinitialized) will generate an assertion fault.
+**
+** P5 ought to be set on every call to this opcode.
+** However, there are places in the code generator will release registers
+** before their are used, under the (valid) assumption that the registers
+** will not be reallocated for some other purpose before they are used and
+** hence are safe to release.
+**
+** This opcode is only available in testing and debugging builds.  It is
+** not generated for release builds.  The purpose of this opcode is to help
+** validate the generated bytecode.  This opcode does not actually contribute
+** to computing an answer.
