pointer_authentication

A comma-separated list of pointer authentication options, each prefixed with + (enable) or - (disable). Available options: aarch64-jump-table-hardening - enable hardened lowering for jump-table dispatch auth-traps - trap immediately on pointer authentication failure calls - enable signing and authentication of all indirect calls elf-got - enable authentication of pointers from GOT (ELF only) function-pointer-type-discrimination - enable type discrimination on C function pointers indirect-gotos - enable signing and authentication of indirect goto targets init-fini - enable signing of function pointers in init/fini arrays init-fini-address-discrimination - enable address discrimination in init/fini arrays intrinsics - pointer authentication intrinsics return-addresses - enable signing and authentication of return addresses typeinfo-vt-ptr-discrimination - incorporate type and address discrimination in authenticated vtable pointers for std::type_info vt-ptr-addr-discrimination - incorporate address discrimination in authenticated vtable pointers vt-ptr-type-discrimination - incorporate type discrimination in authenticated vtable pointers Example: -Zpointer-authentication=+calls,-init-fini`.

This feature has no tracking issue, and is therefore likely internal to the compiler, not being intended for general use.
