   That does not contradict what I wrote.  Both assembly languages are   
   specific to the AMD64 architecture.

   You are confusing builtins with intrinsics.  Builtins are defined by   
   the compiler.  E.g., __builtin_addcll() is supported by clang on all   
   architectures, but is not supported by gcc.  By contrast, the   
   intrinsic _addcarry_u64() is defined by Intel and is supported on gcc   
   and clang (and, I guess icc, and maybe others), but only when   
   compiling for AMD64.
