From 0fcabdeb52b79775173d009ccc179db104dfbb66 Mon Sep 17 00:00:00 2001 From: Sebastian Schuberth Date: Mon, 19 Oct 2009 18:37:05 +0200 Subject: [PATCH] Use faster byte swapping when compiling with MSVC When compiling with MSVC on x86-compatible, use an intrinsic for byte swapping. In contrast to the GCC path, we do not prefer inline assembly here as it is not supported for the x64 platform.
