From 5b0d35eaedbb08d0c11fa4f2b47a24d91aaa294d Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Mon, 12 Dec 2011 01:33:17 +0000 Subject: x86: bswap: remove test for bswap instruction Firstly, this test never worked as intended, always reporting success. Secondly, bswap is available from 486 onward and can thus be assumed present.
