Not all documented RVV 0.7.1 intrinsics supported

[mshabunin]

We have found that some of documented (1) intrinsics are not supported. Please find the reproducer code below. Enabling CASE1 or CASE2 results in an error. Is the documentation wrong or is it a compiler problem?

#include <riscv_vector.h>

#define CASE1 0
#define CASE2 0

int main()
{
#if CASE1    
    // does not work
    // snippet.cpp:16:26: error: 'vlmul_trunc_v_i64m2_i64m1' was not declared in this scope; did you mean 'vget_v_i64m2_i64m1'?
    //   12 |         vint64m1_t dst = vlmul_trunc_v_i64m2_i64m1(src);
    //      |                          ^~~~~~~~~~~~~~~~~~~~~~~~~

        vint64m1_t dst = vlmul_trunc_v_i64m2_i64m1(src);
    }

#endif

        vuint8m1_t bindex;
        vint8m1_t dst = vloxei8_v_i8m1 (data, bindex, 8);
    }

    // does not work
