--- Comment #13 from H.J. Lu <hjl.tools at gmail dot com> ---
Here is the equivalent C code:

---
#include <stdint.h>

#define loop_t uint32_t
#define idx_t uint32_t

void loop(double * const __restrict__ dst,
          double const * const __restrict__ src,
          idx_t const * const __restrict__ idx,
          loop_t const begin,
          loop_t const end)
{
  for (loop_t i =3D begin; i < end; ++i)
    dst[i] =3D 42.0 * src[idx[i]];
}
