| #ifndef NO_WARN_X86_INTRINSICS |
| /* This header is distributed to simplify porting x86_64 code that |
| makes explicit use of Intel intrinsics to powerpc64le. |
| It is the user's responsibility to determine if the results are |
| acceptable and make additional changes as necessary. |
| Note that much code that uses Intel intrinsics can be rewritten in |
| standard C or GNU C extensions, which are more portable and better |
| optimized across multiple targets. |
| |
| In the specific case of X86 SSE (__m128) intrinsics, the 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. Also there are important |
| differences for data format and placement of float scalars in the |
| vector register. For PowerISA Scalar floats in FPRs (left most |
| 64-bits of the low 32 VSRs) is in double format, while X86_64 SSE |
| uses the right most 32-bits of the XMM. These differences require |
| extra steps on POWER to match the SSE scalar float semantics. |
| |
| 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. |
| |
| Another difference is the format and details of the X86_64 MXSCR vs |
| the PowerISA FPSCR / VSCR registers. We recommend applications |
| replace direct access to the MXSCR with the more portable <fenv.h> |
| Posix APIs. */ |
