- #   define __has_feature(x) 0

-+/* Support macros for
-+ *   - Armv8.3-A Pointer Authentication and
-+ *   - Armv8.5-A Branch Target Identification
-+ * features which require emitting a .note.gnu.property section with the
-+ * appropriate architecture-dependent feature bits set.
-+ *
-+ * |AARCH64_SIGN_LINK_REGISTER| and |AARCH64_VALIDATE_LINK_REGISTER| expand to
-+ * PACIxSP and AUTIxSP, respectively. |AARCH64_SIGN_LINK_REGISTER| should be
-+ * used immediately before saving the LR register (x30) to the stack.
-+ * |AARCH64_VALIDATE_LINK_REGISTER| should be used immediately after restoring
-+ * it. Note |AARCH64_SIGN_LINK_REGISTER|'s modifications to LR must be undone
-+ * with |AARCH64_VALIDATE_LINK_REGISTER| before RET. The SP register must also
-+ * have the same value at the two points. For example:
-+ *
-+ *   .global f
-+ *   f:
-+ *     AARCH64_SIGN_LINK_REGISTER
-+ *     stp x29, x30, [sp, #-96]!
-+ *     mov x29, sp
-+ *     ...
-+ *     ldp x29, x30, [sp], #96
-+ *     AARCH64_VALIDATE_LINK_REGISTER
-+ *     ret
-+ *
-+ * |AARCH64_VALID_CALL_TARGET| expands to BTI 'c'. Either it, or
-+ * |AARCH64_SIGN_LINK_REGISTER|, must be used at every point that may be an
-+ * indirect call target. In particular, all symbols exported from a file must
-+ * begin with one of these macros. For example, a leaf function that does not
-+ * save LR can instead use |AARCH64_VALID_CALL_TARGET|:
-+ *
-+ *   .globl return_zero
-+ *   return_zero:
-+ *     AARCH64_VALID_CALL_TARGET
-+ *     mov x0, #0
-+ *     ret
-+ *
-+ * A non-leaf function which does not immediately save LR may need both macros
-+ * because |AARCH64_SIGN_LINK_REGISTER| appears late. For example, the function
-+ * may jump to an alternate implementation before setting up the stack:
-+ *
-+ *   .globl with_early_jump
-+ *   with_early_jump:
-+ *     AARCH64_VALID_CALL_TARGET
-+ *     cmp x0, #128
-+ *     b.lt .Lwith_early_jump_128
-+ *     AARCH64_SIGN_LINK_REGISTER
-+ *     stp x29, x30, [sp, #-96]!
-+ *     mov x29, sp
-+ *     ...
-+ *     ldp x29, x30, [sp], #96
-+ *     AARCH64_VALIDATE_LINK_REGISTER
-+ *     ret
-+ *
-+ *  .Lwith_early_jump_128:
-+ *     ...
-+ *     ret
-+ *
-+ * These annotations are only required with indirect calls. Private symbols that
-+ * are only the target of direct calls do not require annotations. Also note
-+ * that |AARCH64_VALID_CALL_TARGET| is only valid for indirect calls (BLR), not
-+ * indirect jumps (BR). Indirect jumps in assembly are supported through
-+ * |AARCH64_VALID_JUMP_TARGET|. Landing Pads which shall serve for jumps and
-+ * calls can be created using |AARCH64_VALID_JUMP_CALL_TARGET|.
-+ *
-+ * Although not necessary, it is safe to use these macros in 32-bit ARM
-+ * assembly. This may be used to simplify dual 32-bit and 64-bit files.
