From 69a6d0f9562fcd26112a589318c13de66ce1700e Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Thu, 12 Dec 2013 12:43:08 +0200 Subject: SHA-512: Add SSSE3 implementation for x86-64 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * cipher/Makefile.am: Add 'sha512-ssse3-amd64.S'. * cipher/sha512-ssse3-amd64.S: New. * cipher/sha512.c (USE_SSSE3): New. (SHA512_CONTEXT) [USE_SSSE3]: Add 'use_ssse3'. (sha512_init, sha384_init) [USE_SSSE3]: Initialize 'use_ssse3'. [USE_SSSE3] (_gcry_sha512_transform_amd64_ssse3): New. (transform) [USE_SSSE3]: Call SSSE3 implementation. * configure.ac (sha512): Add 'sha512-ssse3-amd64.lo'. -- Patch adds fast SSSE3 implementation of SHA-512 by Intel Corporation.
