| 14 | /* This header file is to help porting code using Intel intrinsics |
| 15 | explicitly from x86_64 to powerpc64/powerpc64le. |
| 16 | |
| 17 | Since PowerPC target doesn't support native 64-bit vector type, we |
| 18 | typedef __m64 to 64-bit unsigned long long in MMX intrinsics, which |
| 19 | works well for _si64 and some _pi32 operations. |
| 20 | |
| 21 | For _pi16 and _pi8 operations, it's better to transfer __m64 into |
| 22 | 128-bit PowerPC vector first. Power8 introduced direct register |
| 23 | move instructions which helps for more efficient implementation. |
| 24 | |
| 25 | It's user's responsibility to determine if the results of such port |
| 26 | are acceptable or further changes are needed. Please note that much |
| 27 | code using Intel intrinsics CAN BE REWRITTEN in more portable and |
| 28 | efficient standard C or GNU C extensions with 64-bit scalar |
| 29 | operations, or 128-bit SSE/Altivec operations, which are more |
| 30 | recommended. */ |
