static __inline __uint32_t
__bswap32(__uint32_t _x)
{
return (__extension__ (({
register __uint32_t __X = (_x);
__asm ("bswap %0" : "+r" (__X));
__X;
})));
}
My new c2hs C parser can parse your example and indeed the whole of that
Node.i file that you posted. The GNU C extensions required were not just
the __extension__ expression but also compound statements as
expressions. The asm statement extension was already implemented.
So when I get this new parser into the mainline c2hs you should try
again.
