/* 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. */
