--- Comment #2 from Li Pan <pan2.li at intel dot com> ---
Thanks for reminding me. Sorry for missing that and will pay more attention=
 to
this next time.

The test case.

#include "riscv_vector.h"

vint64m1_t foo ()
{
    vint64m1_t v;
    return v;
}

According to the RVV SPEC below, the 'vint64m1_t' (aka '__rvv_int64m1_t')
requires the 'zve64x' extensions.
