Member Function Documentation

base()

REG LIEF::assembly::aarch64::operands::Memory::base

(

)

const

The base register.

For str x3, [x8, #8] it would return x8.

classof()

bool LIEF::assembly::aarch64::operands::Memory::classof ( const Operand * op )

static

offset()

offset_t LIEF::assembly::aarch64::operands::Memory::offset

(

)

const

The addressing offset.

It can be either:

• A register (e.g. ldr x0, [x1, x3])
• An offset (e.g. ldr x0, [x1, #8])

shift()

shift_info_t LIEF::assembly::aarch64::operands::Memory::shift

(

)

const

Shift information.

For instance, for ldr x1, [x2, x3, lsl #3] it would return a SHIFT::LSL with a shift_info_t::value set to 3.
