asmjit::FuncArgsAssignment Class Reference [¶]
A helper class that can be used to assign a physical register for each function argument. The assignment is passed to BaseEmitter::emit_args_assignment() function.

Utilities
FuncArgsAssignment::FuncArgsAssignment()explicitnoexcept[1/2][¶]
Creates either a default initialized FuncArgsAssignment or to assignment that links to fd, if non-null.
FuncArgsAssignment::FuncArgsAssignment()defaultnoexcept[2/2][¶]
Copy constructor.
void FuncArgsAssignment::reset()noexcept[¶]
Resets this FuncArgsAssignment to either default constructed state or to assignment that links to fd, if non-null.
FuncArgsAssignment& FuncArgsAssignment::operator=()defaultnoexcept[¶]
Copy assignment.
const FuncDetail* FuncArgsAssignment::func_detail() constnodiscardnoexcept[¶]
Returns the associated FuncDetail of this FuncArgsAssignment.
void FuncArgsAssignment::set_func_detail()noexcept[¶]
Associates FuncDetail with this FuncArgsAssignment.
bool FuncArgsAssignment::has_sa_reg_id() constnodiscardnoexcept[¶]
Returns whether a register to access stack arguments is available.
uint32_t FuncArgsAssignment::sa_reg_id() constnodiscardnoexcept[¶]
Returns a physical ID of a register that can access stack arguments.
void FuncArgsAssignment::set_sa_reg_id(uint32_t reg_id)[¶]
Sets a physical ID of a register that can access stack arguments.
void FuncArgsAssignment::reset_sa_reg_id()[¶]
Resets a physical ID of a register that can access stack arguments.
FuncValue& FuncArgsAssignment::arg(size_t arg_index, size_t value_index)nodiscardnoexcept[1/2][¶]
Returns assigned argument at arg_index and value_index.
Note
arg_index refers to he function argument and value_index refers to a value pack (in case multiple values are passed as a single argument).
const FuncValue& FuncArgsAssignment::arg(size_t arg_index, size_t value_index) constnodiscardnoexcept[2/2][¶]
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
bool FuncArgsAssignment::is_assigned(size_t arg_index, size_t value_index) constnodiscardnoexcept[¶]
Tests whether argument at arg_index and value_index has been assigned.
void FuncArgsAssignment::assign_reg(size_t arg_index, )noexcept[1/2][¶]
Assigns register at arg_index and value index of 0 to reg and an optional type_id.
void FuncArgsAssignment::assign_reg(size_t arg_index, RegType reg_type, uint32_t reg_id, )noexcept[2/2][¶]
Assigns register at arg_index and value index of 0 to reg_type, reg_id, and an optional type_id.
void FuncArgsAssignment::assign_stack(size_t arg_index, int32_t offset, )noexcept[¶]
Assigns stack at arg_index and value index of 0 to offset and an optional type_id.
void FuncArgsAssignment::assign_reg_in_pack(size_t arg_index, size_t value_index, )noexcept[1/2][¶]
Assigns register at arg_index and value_index to reg and an optional type_id.
void FuncArgsAssignment::assign_reg_in_pack(size_t arg_index, size_t value_index, RegType reg_type, uint32_t reg_id, )noexcept[2/2][¶]
Assigns register at arg_index and value_index to reg_type, reg_id, and an optional type_id.
void FuncArgsAssignment::assign_stack_in_pack(size_t arg_index, size_t value_index, int32_t offset, )noexcept[¶]
Assigns stack at arg_index and value_index to offset and an optional type_id.
template<typename... Args>void FuncArgsAssignment::assign_all(Args&&... args)noexcept[¶]
Assigns all argument at once.
Note
This function can be only used if the arguments don't contain value packs (multiple values per argument).
Error FuncArgsAssignment::update_func_frame(FuncFrame& frame) constnoexcept[¶]
Update FuncFrame based on function's arguments assignment.
Note
This function must be called in order to use BaseEmitter::emit_args_assignment(), otherwise the FuncFrame would not contain the information necessary to assign all arguments into the registers and/or stack specified.
const FuncDetail* FuncArgsAssignment::_func_detail {}[¶]
Function detail.
uint8_t FuncArgsAssignment::_sa_reg_id = uint8_t()[¶]
Register that can be used to access arguments passed by stack.
uint8_t FuncArgsAssignment::_reserved[3] {}[¶]
Reserved for future use.
FuncValuePack FuncArgsAssignment::_arg_packs[Globals::kMaxFuncArgs] {}[¶]
Mapping of each function argument.
