/* In the list below, the BUILTIN_<ITERATOR> macros expand to create
   builtins for each of the modes described by <ITERATOR>.  When adding
   new builtins to this list, a helpful idiom to follow is to add
   a line for each pattern in the md file.  Thus, ADDP, which has one
   pattern defined for the VD_BHSI iterator, and one for DImode, has two
   entries below.

   Parameter 1 is the 'type' of the intrinsic.  This is used to
   describe the type modifiers (for example; unsigned) applied to
   each of the parameters to the intrinsic function.

   Parameter 2 is the name of the intrinsic.  This is appended
   to `__builtin_aarch64_<name><mode>` to give the intrinsic name
   as exported to the front-ends.

   Parameter 3 describes how to map from the name to the CODE_FOR_
   macro holding the RTL pattern for the intrinsic.  This mapping is:
   0 - CODE_FOR_aarch64_<name><mode>
   1-9 - CODE_FOR_<name><mode><1-9>
   10 - CODE_FOR_<name><mode>.

   Parameter 4 is the 'flag' of the intrinsic.  This is used to
   help describe the attributes (for example, pure) for the intrinsic
   function.  */
