Detailed Description

Represents a runtime table of function variants sharing a common namespace (referred to internally as FunctionVariantsRuntimeTable in dyld).

Each table holds multiple RuntimeTableEntry instances that map to function implementations optimized for a given KIND.

Member Enumeration Documentation

KIND

enum class LIEF::MachO::FunctionVariants::RuntimeTable::KIND : uint32_t

strong

Enumeration describing the namespace or category of a function variant.

Each FunctionVariants::RuntimeTable is associated with one KIND, which indicates the domain or context under which its variant entries should be considered valid or applicable.

These categories map to the runtime dispatch logic used by dyld when selecting the optimal function variant.

Enumerator
UNKNOWN	Fallback/default kind when the category is not recognized.
PER_PROCESS	Variants that apply on a per-process basis.
SYSTEM_WIDE	Variants that are selected based on system-wide capabilities or configurations.
ARM64	Variants optimized for the ARM64 architecture.
X86_64	Variants optimized for the x86-64 architecture.
