| 14 | /* This header file is to help porting code using Intel intrinsics | 
        ||
| 15 |    explicitly from x86_64 to powerpc64/powerpc64le. | 
        ||
| 16 | |||
| 17 |    Since X86 SSE intrinsics mainly handles __m128 type, PowerPC | 
        ||
| 18 |    VMX/VSX ISA is a good match for vector float SIMD operations. | 
        ||
| 19 |    However scalar float operations in vector (XMM) registers require | 
        ||
| 20 |    the POWER8 VSX ISA (2.07) level. There are differences for data | 
        ||
| 21 |    format and placement of float scalars in the vector register, which | 
        ||
| 22 |    require extra steps to match SSE scalar float semantics on POWER. | 
        ||
| 23 | |||
| 24 |    It should be noted that there's much difference between X86_64's | 
        ||
| 25 |    MXSCR and PowerISA's FPSCR/VSCR registers. It's recommended to use | 
        ||
| 26 |    portable <fenv.h> instead of access MXSCR directly. | 
        ||
| 27 | |||
| 28 |    Most SSE scalar float intrinsic operations can be performed more | 
        ||
| 29 |    efficiently as C language float scalar operations or optimized to | 
        ||
| 30 |    use vector SIMD operations. We recommend this for new applications. */ |
