asmjit::FuncDetail Class Reference
Function detail - CallConv and expanded FuncSignature.
Function detail is architecture and OS dependent representation of a function. It contains a materialized calling convention and expanded function signature so all arguments have assigned either register type/id or stack address.

FuncDetail::FuncDetail()noexcept[1/2][¶]
Creates a default constructed FuncDetail.
FuncDetail::FuncDetail(const FuncDetail& other)defaultnoexcept[2/2][¶]
Copy constructor.
Function details are copyable.
Error FuncDetail::init(const FuncSignature& signature, const Environment& environment)noexcept[¶]
Initializes this FuncDetail to the given signature.
FuncDetail& FuncDetail::operator=(const FuncDetail& other)defaultnoexcept[¶]
Assignment operator, copies other to this FuncDetail.
void FuncDetail::reset()noexcept[¶]
Resets the function detail to its default constructed state.
const CallConv& FuncDetail::callConv() constnoexcept[¶]
Returns the function's calling convention, see CallConv.
CallConvFlags FuncDetail::flags() constnoexcept[¶]
Returns the associated calling convention flags, see CallConv::Flags.
bool FuncDetail::hasFlag(CallConvFlags ccFlag) constnoexcept[¶]
Checks whether a CallConv flag is set, see CallConv::Flags.
bool FuncDetail::hasRet() constnoexcept[¶]
Tests whether the function has a return value.
uint32_t FuncDetail::argCount() constnoexcept[¶]
Returns the number of function arguments.
FuncValuePack& FuncDetail::retPack()noexcept[1/2][¶]
Returns function return values.
const FuncValuePack& FuncDetail::retPack() constnoexcept[2/2][¶]
Returns function return values.
FuncValue& FuncDetail::ret(size_t valueIndex = 0)noexcept[1/2][¶]
Returns a function return value associated with the given valueIndex.
const FuncValue& FuncDetail::ret(size_t valueIndex = 0) constnoexcept[2/2][¶]
Returns a function return value associated with the given valueIndex (const).
FuncValuePack* FuncDetail::argPacks()noexcept[1/2][¶]
Returns function argument packs array.
const FuncValuePack* FuncDetail::argPacks() constnoexcept[2/2][¶]
Returns function argument packs array (const).
FuncValuePack& FuncDetail::argPack(size_t argIndex)noexcept[1/2][¶]
Returns function argument pack at the given argIndex.
const FuncValuePack& FuncDetail::argPack(size_t argIndex) constnoexcept[2/2][¶]

FuncValue& FuncDetail::arg(size_t argIndex, size_t valueIndex = 0)noexcept[1/2][¶]
Returns an argument at valueIndex from the argument pack at the given argIndex.
const FuncValue& FuncDetail::arg(size_t argIndex, size_t valueIndex = 0) constnoexcept[2/2][¶]
Returns an argument at valueIndex from the argument pack at the given argIndex (const).
void FuncDetail::resetArg(size_t argIndex)noexcept[¶]
Resets an argument at the given argIndex.
If the argument is a parameter pack (has multiple values) all values are reset.
