maat::ir::Param class

Base class for parameters to be used in IR instructions.

Contents

❱   Public types

enum class Type: uint8_t { CST, REG, TMP, ADDR, NONE }

❱   Public static functions

static auto None() -> const Param&
Return the 'None' parameter.

❱   Constructors, destructors, conversion operators

Param()
Constructor, create an empty None parameter.
Param(const Param& other) defaulted
Copy constructor.
Param(Type type, uint64_t val, size_t hb, size_t lb)
Constructor.

❱   Public functions

auto operator=(const Param& other) -> Param&
Assignment operator.
auto operator=(Param&& other) -> Param& defaulted
Move semantics operator.
auto is_cst() const -> bool
Return true if it is a constant parameter.
auto is_cst(cst_t val) const -> bool
Return true if it is a constant parameter of value 'val'.
auto is_reg() const -> bool
Return true if it is a CPU register parameter.
auto is_reg(reg_t reg) const -> bool
Return if it is the CPU register parameter for 'reg'.
auto is_tmp() const -> bool
Return true if it is a tmp register parameter.
auto is_tmp(tmp_t tmp) const -> bool
Return true if it is the tmp register parameter for 'tmp'.
auto is_addr() const -> bool
Return true if it is a memory address.
auto is_none() const -> bool
Return true if the parameter is empty.
auto cst() const -> cst_t
Return the constant if constant parameter.
auto reg() const -> reg_t
Return the CPU register if register parameter.
auto tmp() const -> tmp_t
Return the tmp register if tmp parameter.
auto addr() const -> addr_t
Return the address if address parameter.
auto size() const -> size_t
Return the size in bits of the parameter.

❱   Public variables

Type type
Type of this parameter.
size_t hb
Higher bit of the parameter.
size_t lb
Lower bit of the parameter.

enum class maat::ir::Param::Type: uint8_t

Types of parameters/operands in the IR

Enumerators
CST

A constant value.
REG

References an actual CPU register in the arch being lifted.
TMP

References a temporary register used to hold temporary values but don't correspond to actual CPU registers.
ADDR

References a value stored in the RAM at a given address.
NONE

None.
