- * This implementation should never be optimized out by the compiler
- *
- * This implementation for mbedtls_platform_zeroize() was inspired from Colin
- * Percival's blog article at:
- *
- * http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
- *
- * It uses a volatile function pointer to the standard memset(). Because the
- * pointer is volatile the compiler expects it to change at
- * any time and will not optimize out the call that could potentially perform
- * other operations on the input buffer instead of just setting it to 0.
- * Nevertheless, as pointed out by davidtgoldblatt on Hacker News
- * (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
- * details), optimizations of the following form are still possible:
- *
- * if( memset_func != memset )
- *     memset_func( buf, 0, len );
- *
- * Note that it is extremely difficult to guarantee that
- * mbedtls_platform_zeroize() will not be optimized out by aggressive compilers
- * in a portable way. For this reason, Mbed TLS also provides the configuration
- * option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
- * mbedtls_platform_zeroize() to use a suitable implementation for their
- * platform and needs.
