Constructor Details

DefaultPcodeTraceRegistersAccess

protected DefaultPcodeTraceRegistersAccess(TracePlatform platform,
 long snap,
 TraceThread thread,
 int frame,
 TraceTimeViewport viewport)

Construct a shim

Parameters:

platform - the associated platform

snap - the associated snap

thread - the associated thread whose registers to access

frame - the associated frame, or 0 if not applicable

viewport - the viewport, set to the same snapshot

Method Details

getMemoryOps

protected TraceMemorySpace getMemoryOps(boolean createIfAbsent)

Description copied from class: AbstractPcodeTraceDataAccess

Get the interface for accessing trace memory or registers

Specified by:

getMemoryOps in class AbstractPcodeTraceDataAccess

Parameters:

createIfAbsent - in the case of registers, whether to create the missing space

Returns:

the operations, or null

getPropertyOps

public <T> TracePropertyMapSpace<T> getPropertyOps(String name,
 Class<T> type,
 boolean createIfAbsent)

Specified by:

getPropertyOps in interface InternalPcodeTraceDataAccess

isRegisterKnown

protected boolean isRegisterKnown(PcodeThread<?> thread,
 Register register)

Check if a register has a TraceMemoryState.KNOWN value for the given thread

Parameters:

thread - the thread

register - the register

Returns:

true if known

initializeThreadContext

public void initializeThreadContext(PcodeThread<?> thread)

Description copied from interface: PcodeTraceRegistersAccess

Initialize the given p-code thread's context register using register context from the trace at the thread's program counter

This is called during thread construction, after the program counter is initialized from the same trace thread. This will ensure that the instruction decoder starts in the same mode as the disassembler was for the trace.

Specified by:

initializeThreadContext in interface PcodeTraceRegistersAccess

Parameters:

thread - the thread to initialize

toOverlay

protected Address toOverlay(Address address)

Description copied from class: AbstractPcodeTraceDataAccess

If this shim is associated with a (register) overlay space, translate the given address into it

Specified by:

toOverlay in class AbstractPcodeTraceDataAccess

Parameters:

address - the physical (register) address

Returns:

the overlay address

toOverlay

protected AddressRange toOverlay(AddressRange range)

Specified by:

toOverlay in class AbstractPcodeTraceDataAccess

Parameters:

range - the physical range

Returns:

the overlay range

See Also:

• AbstractPcodeTraceDataAccess.toOverlay(Address)

toOverlay

protected AddressSetView toOverlay(AddressSetView set)

Specified by:

toOverlay in class AbstractPcodeTraceDataAccess

Parameters:

set -

Returns:
