From e03b56863d2bca3e649e81531c1b0299524481ae Mon Sep 17 00:00:00 2001 From: Marc-André Lureau Date: Wed, 23 Mar 2022 19:57:17 +0400 Subject: Replace config-time define HOST_WORDS_BIGENDIAN MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.
