Detailed Description

A class responsible for performing architecture specific operations in case of an ARM chip emulation.

Constructor & Destructor Documentation

ArchManagerARM()

arion_arm::ArchManagerARM::ArchManagerARM ( )

inline

Builder for ArchManagerARM instances.

Member Function Documentation

curr_cs()

csh * arion_arm::ArchManagerARM::curr_cs ( )

overridevirtual

Retrieves a Capstone engine associated with this instance, based on the current mode of the ARM CPU (ARM or THUMB).

Returns

The Capstone engine.

Implements arion::ArchManager.

curr_ks()

ks_engine * arion_arm::ArchManagerARM::curr_ks ( )

overridevirtual

Retrieves a Keystone engine associated with this instance, based on the current mode of the ARM CPU (ARM or THUMB).

Returns

The Keystone engine.

Implements arion::ArchManager.

dump_tls()

arion::ADDR arion_arm::ArchManagerARM::dump_tls ( )

overridevirtual

Retrieves the current Thread Local Storage (TLS) address from the emulation context.

Returns

The TLS address.

Implements arion::ArchManager.

enable_vfp()

void arion_arm::ArchManagerARM::enable_vfp ( )

private

Enables the Vector Floating Point (VFP) unit of the ARM emulated chip.

int_hook()

static void arion_arm::ArchManagerARM::int_hook ( std::shared_ptr< arion::Arion >  arion, uint32_t  intno, void *  user_data  )

staticprivate

Interrupt hook used to detect syscalls.

Parameters

[in]	arion	The Arion instance responsible for the interrupt.
[in]	intno	The interrupt number.
[in]	user_data	Additional user data.

is_thumb()

bool arion_arm::ArchManagerARM::is_thumb ( )

private

Checks whether the ARM CPU is in ARM or THUMB mode.

Returns

True if the ARM CPU is in THUMB mode.

load_tls()

void arion_arm::ArchManagerARM::load_tls ( arion::ADDR  new_tls )

overridevirtual

Defines a Thread Local Storage (TLS) address to apply to the emulation.

Parameters

[in]

new_tls

The new TLS address.

Implements arion::ArchManager.

prerun_hook()

void arion_arm::ArchManagerARM::prerun_hook ( arion::ADDR &  start )

overridevirtual

Performs ARM specific operations each time emulation starts.

Parameters

[in,out]

start

The emulation start address.

Reimplemented from arion::ArchManager.

setup()

void arion_arm::ArchManagerARM::setup ( )

overrideprivatevirtual

Prepares the ArchManagerARM for emulation.

Implements arion::ArchManager.
