            Bug ID: 276282
           Summary: vectorized code fails on powerpc64le: typedef __vector
                    uint8_t __m128i; in the port misc/randomx
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: misc

This code fails:
#elif defined(__PPC64__) && defined(__ALTIVEC__) && defined(__VSX__) //sadly
only POWER7 and newer will be able to use SIMD acceleration. Earlier processors
cant use doubles or 64 bit integers with SIMD
#include <cstdint>
#include <stdexcept>
#include <cstdlib>
#include <altivec.h>
#undef vector
#undef pixel
#undef bool

typedef __vector uint8_t __m128i;
typedef __vector uint32_t __m128l;
typedef __vector int      __m128li;
typedef __vector uint64_t __m128ll;
typedef __vector double __m128d;

I don't know whether this code is valid, but based on the presence of #if
defined(__PPC64__) - it likely is valid.

See the linked log URL for details.
