This revision now requires changes to proceed.
Instead of not using `__builtin_bswap{32,64}` entirely, we should check if
they're available.
You can use the clang feature-checking macro `__has_builtin` (and if it doesn't
exist you can define it). So you could amend this patch like so:
#if !defined(__has_builtin)
#define __has_builtin(x) 0
#endif
#if __has_builtin(__builtin_bswap32)
#define bswap_32(x) __builtin_bswap32(x)
#elif _MSC_VER
#define bswap_32(x) _byteswap_ulong(x)
#else
#include <byteswap.h>
#endif
