Value:

void executionstate_pop_stackframe

(

executionstate_t *

es

)

Restore callee-saved registers (including the RA register), set the stack pointer to the next stackframe, set the PC to the return address of the popped frame.

*** This function imitates the effects of the method epilog *** *** and returning from the method call. ***

Parameters

es	Execution state to be modified. NOTE: es->code and es->pv are NOT updated.

void executionstate_unwind_exception	(	executionstate_t *	es,
		java_handle_t *	e
	)

Performs stack unwinding in case of an exception.

This is done by popping frames off the given execution state until a frame is reached for which there is a handler. Execution will continue at the handler site once the execution state is written back to the machine.

Parameters

es	Execution state to be modified.
e	The thrown exception object.

This is specified in: The Java(TM) Virtual Machine Specification, Second Edition Section 3.6.5: Abrupt Method Invocation Completion
