From 17ddce4692b31af4374b28cd40b9f25e8ed629cd Mon Sep 17 00:00:00 2001 From: "Bradley T. Hughes" Date: Fri, 24 Feb 2012 11:11:02 +0100 Subject: Remove Q_BYTE_ORDER and -*-endian arguments from configures Do not write Q_BYTE_ORDER to qconfig.h in the configures. Instead, we #define Q_BYTE_ORDER in qprocessordetection.h, since many CPUs only support a single endian format. For bi-endian processors, we set Q_BYTE_ORDER depending on how the preprocessor sets __BYTE_ORDER__, __BIG_ENDIAN__, or __LITTLE_ENDIAN__ (instead of using a compile test to do so). For operating systems that only support a single byte order, we can check for Q_OS_* in addition to the preprocessor macros above. This is possible because qprocessordetection.h is included by qglobal.h after Q_OS_* and Q_CC_* detection has been done. Do this for Windows CE, which is always little- endian according to MSDN.
