Author: emaste Date: Wed Sep 25 16:49:22 2019 New Revision: 352689 URL: https://svnweb.freebsd.org/changeset/base/352689 Log: remove obsolete i386 MD memchr implementation bde reports (in a reply to r351700 commit mail): This uses scasb, which was last optimal on the 8086, or perhaps the original i386. On freefall, it is several times slower than the naive translation of the naive C code.
