#ifndef NO_WARN_X86_INTRINSICS
/* 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. */
