Generates instruction to that creates a new LockState object and saves it to the lockstate variable.

Parameters:

markerType - debug marker type

lockVars - variables for lock/synchpoint functionality

Returns:

instructions to push a new LockState object

Throws:

java.lang.NullPointerException - if any argument is null

java.lang.IllegalArgumentException - if lock variables aren't set (the method doesn't contain any monitorenter/monitorexit instructions)

Generates instruction to enter all monitors in the LockState object sitting in the lockstate variable.

Parameters:

markerType - debug marker type

lockVars - variables for lock/synchpoint functionality

Returns:

instructions to enter all monitors in the LockState object

Throws:

java.lang.NullPointerException - if any argument is null

java.lang.IllegalArgumentException - if lock variables aren't set (the method doesn't contain any monitorenter/monitorexit instructions)

exitStoredMonitors
