[LLVMdev] FD_ZERO unsupported inline asm on 64 bit
..._64.
This code worked just fine with older versions of llvm-gcc on 32 bit Linux.
FD_ZERO is defined in /usr/include/bits/select.h like this:
# if __WORDSIZE == 64
# define __FD_ZERO_STOS "stosq"
# define __FD_SET_BTS "btsq"
# define __FD_CLR_BTR "btrq"
# define __FD_ISSET_BT "btq"
# else
# define __FD_ZERO_STOS "stosl"
# define __FD_SET_BTS "btsl"
# define __FD_CLR_BTR "btrl"
# define __FD_ISSET_BT "btl"
# endif
# define __FD_ZERO(fdsp) \
do {...
