Author: emaste Date: Wed Jul 26 23:14:21 2017 New Revision: 321593 URL: https://svnweb.freebsd.org/changeset/base/321593 Log: MFC r319718: arm64: add ".arch armv8-a+crc" to allow use of crc instructions With Clang 5.0 the .arch directive is required, otherwise Clang complains "error: instruction requires: crc". This was reported in D10499 but not added initially, because clang 3.8 available on a ref machine reported unknown directive. Clang 4.0 allows but does not require the directive.
