Method Detail

deliverException

public void deliverException(CompiledMethod compiledMethod,
                             Address catchBlockInstructionAddress,
                             Throwable exceptionObject,
                             ArchitectureSpecific.Registers registers)
Pass control to a catch block.

Specified by:
deliverException in class ExceptionDeliverer
Parameters:
compiledMethod - method whose catch block is to receive control
catchBlockInstructionAddress - instruction address at which to begin execution of catch block
exceptionObject - exception object to be passed as argument to catch block
registers - registers to be loaded before passing control to catch block

unwindStackFrame

public void unwindStackFrame(CompiledMethod compiledMethod,
                             ArchitectureSpecific.Registers registers)
Unwind a stackframe.

Specified by:
unwindStackFrame in class ExceptionDeliverer
Parameters:
compiledMethod - method whose stackframe is to be unwound
registers - thread state to be updated by restoring non-volatiles and unwinding the stackframe
