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