bool TypeUtils::is_mmx(TypeId type_id)constexprstaticnodiscardnoexcept[¶]
Tests whether a given type is an MMX register.
Note
MMX functionality is in general deprecated on X86 architecture. AsmJit provides it just for completeness.
bool TypeUtils::is_mmx32(TypeId type_id)constexprstaticnodiscardnoexcept[¶]
Tests whether a given type is an MMX register, which only uses the low 32 bits of data (only specific cases).
Note
MMX functionality is in general deprecated on X86 architecture. AsmJit provides it just for completeness.
bool TypeUtils::is_mmx64(TypeId type_id)constexprstaticnodiscardnoexcept[¶]
Tests whether a given type is an MMX register, which uses 64 bits of data (default).
Note
MMX functionality is in general deprecated on X86 architecture. AsmJit provides it just for completeness.
bool TypeUtils::is_vec(TypeId type_id)constexprstaticnodiscardnoexcept[¶]

template<typename T>TypeId TypeUtils::type_id_of_t()constexprstaticnoexcept[¶]
Returns a corresponding TypeId of T type.
uint32_t TypeUtils::deabstract_delta_of_size(uint32_t register_size)constexprstaticnodiscardnoexcept[¶]
Returns offset needed to convert a kIntPtr and kUIntPtr TypeId into a type that matches register_size (general-purpose register size). If you find such TypeId it's then only about adding the offset to it.
For example:
uint32_t register_size = /* 4 or 8 *‍/;
uint32_t deabstract_delta = TypeUtils::deabstract_delta_of_size(register_size);
TypeId type_id = 'some type-id';
// Normalize some type_id into a non-abstract type_id.
if (TypeUtils::is_abstract(type_id)) type_id += deabstract_delta;
// The same, but by using TypeUtils::deabstract() function.
type_id = TypeUtils::deabstract(type_id, deabstract_delta);
TypeId TypeUtils::deabstract(TypeId type_id, uint32_t deabstract_delta)constexprstaticnodiscardnoexcept[¶]
Deabstracts a given type_id into a native type by using deabstract_delta, which was previously calculated by calling deabstract_delta_of_size() with a target native register size.
