Member Functions

Initialization & Reset

These initialize the whole FuncValue to either register or stack. Useful when you know all of these properties and wanna just set it up.

void init_type_id(TypeId type_id) noexcept

void init_reg(RegType reg_type, uint32_t reg_id, TypeId type_id, uint32_t flags = 0) noexcept

void init_stack(int32_t offset, TypeId type_id) noexcept

void reset() noexcept

Assign

These initialize only part of FuncValue, useful when building FuncValue incrementally. The caller should first init the type-id by calling init_type_id and then continue building either register or stack.

void FuncValue::init_type_id(
TypeId type_id
)noexcept[¶]

Initializes this FuncValue only to the type_id provided - the rest of the values will be cleared.

void FuncValue::init_reg(
RegType reg_type,
uint32_t reg_id,
TypeId type_id,
uint32_t flags = 0
)noexcept[¶]

Initializes this FuncValue to a register of reg_type, reg_id, and assigns its type_id and flags.

void FuncValue::init_stack(
int32_t offset,
TypeId type_id
)noexcept[¶]

Initializes this FuncValue to a stack at the given offset and assigns its type_id.

void FuncValue::reset()noexcept[¶]

Resets the value to its unassigned state.

void FuncValue::assign_reg_data(
RegType reg_type,
uint32_t reg_id
)noexcept[¶]

Assigns a register of reg_type and reg_id.

void FuncValue::assign_stack_offset(
int32_t offset
)noexcept[¶]

Assigns a stack location at offset.

FuncValue::operator bool() constexplicitnoexcept[¶]

Returns true if the value is initialized (explicit bool cast).

bool FuncValue::has_flag(
uint32_t flag
) constnodiscardnoexcept[¶]

Tests whether the FuncValue has a flag flag set.

void FuncValue::add_flags(
uint32_t flags
)noexcept[¶]

Adds flags to FuncValue.

void FuncValue::clear_flags(
uint32_t flags
)noexcept[¶]

Clears flags of FuncValue.

bool FuncValue::is_initialized() constnodiscardnoexcept[¶]

Tests whether the value is initialized (i.e. contains a valid data).

bool FuncValue::is_reg() constnodiscardnoexcept[¶]

Tests whether the argument is passed by register.

bool FuncValue::is_stack() constnodiscardnoexcept[¶]

Tests whether the argument is passed by stack.

bool FuncValue::is_assigned() constnodiscardnoexcept[¶]

Tests whether the argument is passed by register.

bool FuncValue::is_indirect() constnodiscardnoexcept[¶]

Tests whether the argument is passed through a pointer (used by WIN64 to pass XMM|YMM|ZMM).

bool FuncValue::is_done() constnodiscardnoexcept[¶]

Tests whether the argument was already processed (used internally).

RegType FuncValue::reg_type() constnodiscardnoexcept[¶]

Returns a register type of the register used to pass function argument or return value.

void FuncValue::set_reg_type(
RegType reg_type
)noexcept[¶]

Sets a register type of the register used to pass function argument or return value.

uint32_t FuncValue::reg_id() constnodiscardnoexcept[¶]

Returns a physical id of the register used to pass function argument or return value.

void FuncValue::set_reg_id(
uint32_t reg_id
)noexcept[¶]

Sets a physical id of the register used to pass function argument or return value.

int32_t FuncValue::stack_offset() constnodiscardnoexcept[¶]

Returns a stack offset of this argument.

void FuncValue::set_stack_offset(
int32_t offset
)noexcept[¶]

Sets a stack offset of this argument.

bool FuncValue::has_type_id() constnodiscardnoexcept[¶]

Tests whether the argument or return value has associated TypeId.

TypeId FuncValue::type_id() constnodiscardnoexcept[¶]

Returns a TypeId of this argument or return value.

void FuncValue::set_type_id(
TypeId type_id
)noexcept[¶]
