Constructor & Destructor Documentation

MemoryRecorder()

arion::MemoryRecorder::MemoryRecorder ( std::weak_ptr< Arion >  arion )

inline

Builder for MemoryRecorder instances.

Parameters

[in]

arion

The Arion instance being recorded.

Member Function Documentation

add_edit()

void arion::MemoryRecorder::add_edit ( std::shared_ptr< ARION_MEM_EDIT >  edit )

private

Records a new memory access.

Parameters

[in]

edit

The memory access to record.

clear()

void arion::MemoryRecorder::clear

(

)

Clears all recorded memory accesses.

get_edits()

std::vector< std::shared_ptr< ARION_MEM_EDIT > > arion::MemoryRecorder::get_edits

(

)

Retrieves all recorded memory accesses.

Returns

A vector of ARION_MEM_EDIT instances representing the recorded memory accesses.

initialize()

static std::unique_ptr< MemoryRecorder > arion::MemoryRecorder::initialize ( std::weak_ptr< Arion >  arion )

static

Instanciates and initializes new MemoryRecorder objects with some parameters.

Parameters

[in]

arion

The Arion instance being recorded.

Returns

A new Memory recorder instance.

start()

void arion::MemoryRecorder::start

(

)

Starts recording memory accesses.

stop()

void arion::MemoryRecorder::stop

(

)

Stops recording memory accesses.

write_mem_hook()

static bool arion::MemoryRecorder::write_mem_hook ( std::shared_ptr< Arion >  arion, uc_mem_type  type, uint64_t  addr, int  size, int64_t  val, void *  user_data  )

staticprivate

The function called when a memory write occurs to the associated Arion instance.

Parameters

[in]	arion	Arion instance that triggered the hook.
[in]	type	Type of memory being access.
[in]	addr	Memory address where the write occurred.
[in]	size	Size of the write in bytes.
[in]	val	Value written to memory.
[in]	user_data	Optional user-defined data passed to the hook.
