--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase (removing the C++ lambda):

#include <arm_sve.h>
svint8_t doit(svbool_t ptrue, svint8_t in) {
    int8_t data [2000];
    svst1(ptrue, (int8_t *)data, in);
    for (int _i = (int)svcntb()/2; _i < (int)svcntb(); ++_i)
        data[_i] = data[_i-(int)svcntb()];
    in = svld1(ptrue, data);
    return in;
}

Confirmed.
