27#ifndef NO_WARN_X86_INTRINSICS
28/* This header is distributed to simplify porting x86_64 code that
29   makes explicit use of Intel intrinsics to powerpc64le.
30   It is the user's responsibility to determine if the results are
31   acceptable and make additional changes as necessary.
32   Note that much code that uses Intel intrinsics can be rewritten in
33   standard C or GNU C extensions, which are more portable and better
34   optimized across multiple targets.
35
36   In the specific case of X86 SSE3 intrinsics, the PowerPC VMX/VSX ISA
37   is a good match for most SIMD operations.  However the Horizontal
38   add/sub requires the data pairs be permuted into a separate
39   registers with vertical even/odd alignment for the operation.
40   And the addsub operation requires the sign of only the even numbered
41   elements be flipped (xored with -0.0).
42   For larger blocks of code using these intrinsic implementations,
43   the compiler be should be able to schedule instructions to avoid
44   additional latency.
45
46   In the specific case of the monitor and mwait instructions there are
47   no direct equivalent in the PowerISA at this time.  So those
48   intrinsics are not implemented.  */
