When `pauthtest` is either passed as environment part of AArch64 Linux triple or passed via `-mabi=`, enable the following ptrauth flags: - `intrinsics`; - `calls`; - `returns`; - `auth-traps`; - `vtable-pointer-address-discrimination`; - `vtable-pointer-type-discrimination`; - `init-fini`. Some related stuff is still subject to change, and the ABI itself might be changed, so end users are not expected to use this and the ABI name has 'test' suffix. If `-mabi=pauthtest` option is used, it's normalized to effective triple. When the environment part of the effective triple is `pauthtest`, try to use `aarch64-linux-pauthtest` as multilib directory. The following is not supported: - combination of `pauthtest` ABI with any branch protection scheme except BTI; - explicit set of environment part of the triple to a value different from `pauthtest` in combination with `-mabi=pauthtest`; - usage on non-Linux OS. --------- Co-authored-by: Anatoly Trosinenko <atrosinenko@accesssoftek.com>
