asmjit::FuncValuePack Struct Reference

Contains multiple FuncValue instances in an array so functions that use multiple registers for arguments or return values can represent all inputs and outputs.

FuncValue _values[Globals::kMaxValuePack]

Member Functions

Initialization & Reset

void reset() noexcept

Accessors

uint32_t count() const noexcept

FuncValue* values() noexcept

const FuncValue* values() const noexcept

void resetValue(size_t index) noexcept

bool hasValue(size_t index) noexcept

void assignReg(size_t index, const BaseReg& reg, TypeId typeId = TypeId::kVoid) noexcept

void assignReg(size_t index, RegType regType, uint32_t regId, TypeId typeId = TypeId::kVoid) noexcept

void assignStack(size_t index, int32_t offset, TypeId typeId = TypeId::kVoid) noexcept

FuncValue& operator[](size_t index)

const FuncValue& operator[](size_t index) const

void FuncValuePack::reset()noexcept

Resets all values in the pack.

uint32_t FuncValuePack::count() constnoexcept

Calculates how many values are in the pack, checking for non-values from the end.

FuncValue* FuncValuePack::values()noexcept[1/2]

Returns values in this value in the pack.

Note

The returned array has exactly Globals::kMaxValuePack elements.

const FuncValue* FuncValuePack::values() constnoexcept[2/2]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

void FuncValuePack::resetValue(

size_t index

)noexcept

Resets a value at the given index in the pack, which makes it unassigned.

bool FuncValuePack::hasValue(

size_t index

)noexcept

Tests whether the value at the given index in the pack is assigned.

void FuncValuePack::assignReg(

size_t index,

const BaseReg& reg,

TypeId typeId = TypeId::kVoid

)noexcept[1/2]

Assigns a register at the given index to reg and an optional typeId.

void FuncValuePack::assignReg(

size_t index,

RegType regType,

uint32_t regId,

TypeId typeId = TypeId::kVoid

)noexcept[2/2]

Assigns a register at the given index to regType, regId, and an optional typeId.

void FuncValuePack::assignStack(

size_t index,

int32_t offset,

TypeId typeId = TypeId::kVoid

)noexcept

Assigns a stack location at the given index to offset and an optional typeId.

FuncValue& FuncValuePack::operator[](

size_t index

)[1/2]

Accesses the value in the pack at the given index.

Note

The maximum index value is Globals::kMaxValuePack - 1.

const FuncValue& FuncValuePack::operator[](

size_t index

) const[2/2]

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

FuncValue FuncValuePack::_values[Globals::kMaxValuePack]

Values of the pack.
