Subject: Remove the benchmark part of the selftest. It uses the undocumented
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=ad9dab528902b19287655e3570116f0cbd6bdb01;p=openbsd

Remove the benchmark part of the selftest. It uses the undocumented
OPENSSL_rdtsc() routine to get a high-precision timestamp, and (although
this is the only user of this routine in libcrypto) forces every platform
willing to provide fast assembly versions of some routines, to also
provide OPENSSL_rdtsc().
