#ifndef NO_WARN_X86_INTRINSICS
/* This header file is to help porting code using Intel intrinsics
   explicitly from x86_64 to powerpc64/powerpc64le.

   Since PowerPC target doesn't support native 64-bit vector type, we
   typedef __m64 to 64-bit unsigned long long in MMX intrinsics, which
   works well for _si64 and some _pi32 operations.

   For _pi16 and _pi8 operations, it's better to transfer __m64 into
   128-bit PowerPC vector first. Power8 introduced direct register
   move instructions which helps for more efficient implementation.

   It's user's responsibility to determine if the results of such port
   are acceptable or further changes are needed. Please note that much
   code using Intel intrinsics CAN BE REWRITTEN in more portable and
   efficient standard C or GNU C extensions with 64-bit scalar
   operations, or 128-bit SSE/Altivec operations, which are more
   recommended. */
