-/* Pointer bounds checking is a no-op unless running on hardware
-   supporting Intel MPX (Intel Skylake or better).  Also, it requires
-   GCC 5 and Linux kernel 3.19, or later.  Configure with
-   CFLAGS='-fcheck-pointer-bounds -mmpx', perhaps with
-   -fchkp-first-field-has-own-bounds thrown in.
-
-   Although pointer bounds checking can help during debugging, it is
-   disabled by default because it hurts performance significantly.
-   The checking does not detect all pointer errors.  For example, a
-   dumped Emacs might not detect a bounds violation of a pointer that
-   was created before Emacs was dumped.  */
