Generally it's much better and -cleaner to check feature test macros than check for particular -implementation (and that is also why musl libc doesn't define __MUSL__). -Unfortunately I am not aware of feature test macro guaranteeing endian.h -availability. - -The simple solution is to add checking for compiler's pre-defined macros -(__BYTE_ORDER__, __ORDER_LITTLE_ENDIAN__, __ORDER_LITTLE_ENDIAN__) after -checking macros coming from system headers, i.e. <endian.h> in this case -(__BYTE_ORDER, __BIG_ENDIAN, __LITTLE_ENDIAN). - -That way we can better support new architectures w/o hardcoding their -endianness, which is especially useful if they support both. ---- - librhash/byte_order.h | 4 ++++ - 1 file changed, 4 insertions(+) - -diff --git a/librhash/byte_order.h b/librhash/byte_order.h -index 77b8bb9..5cb081e 100644 ---- a/librhash/byte_order.h -+++ b/librhash/byte_order.h -@@ -38,6 +38,8 @@ extern "C" { - /* detect CPU endianness */ - #if (defined(__BYTE_ORDER) && defined(__LITTLE_ENDIAN) && \ - __BYTE_ORDER == __LITTLE_ENDIAN) || \ -+ (defined(__BYTE_ORDER__) && defined(__ORDER_LITTLE_ENDIAN__) && \ -+ __BYTE_ORDER__ == __ORDER_LITTLE_ENDIAN__) || \ - defined(CPU_IA32) || defined(CPU_X64) || \ - defined(__ia64) || defined(__ia64__) || defined(__alpha__) || defined(_M_ALPHA) || \ - defined(vax) || defined(MIPSEL) || defined(_ARM_) || defined(__arm__) -@@ -46,6 +48,8 @@ extern "C" { - # define IS_LITTLE_ENDIAN 1 - #elif (defined(__BYTE_ORDER) && defined(__BIG_ENDIAN) && \ - __BYTE_ORDER == __BIG_ENDIAN) || \ -+ (defined(__BYTE_ORDER__) && defined(__ORDER_BIG_ENDIAN__) && \ -+ __BYTE_ORDER__ == __ORDER_BIG_ENDIAN__) || \ - defined(__sparc) || defined(__sparc__) || defined(sparc) || \ - defined(_ARCH_PPC) || defined(_ARCH_PPC64) || defined(_POWER) || \ - defined(__POWERPC__) || defined(POWERPC) || defined(__powerpc) || \ --- -2.8.3 - |
