From a3b20f67b35e26813d02e08043db2a5d9263f255 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 6 May 2012 13:40:19 -0400 Subject: [PATCH] take byte order from gcc if gcc has defined it this only works with gcc 4.6 and later, but it allows us to support non-default endianness on archs like arm, mips, ppc, etc. that can do both without having separate header sets for both variants, and it saves one #include even on fixed-endianness archs like x86. --- include/endian.h | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/include/endian.h b/include/endian.h index 9652c30b..41ca1711 100644 --- a/include/endian.h +++ b/include/endian.h @@ -5,7 +5,11 @@ #define __BIG_ENDIAN 4321 #define __PDP_ENDIAN 3412 +#if defined(__GNUC__) && defined(__BYTE_ORDER__) +#define __BYTE_ORDER __BYTE_ORDER__ +#else #include +#endif #if defined(_GNU_SOURCE) || defined(_BSD_SOURCE) -- 2.25.1
