--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I suspect if __riscv_vle8_v_u8m1 gets lowered into a load on the gimple lev=
el,
it might just work ...

But it gets expanded as:
(insn 14 13 0 (set (reg/v:RVVM1QI 134 [ varrD.56526 ])
        (if_then_else:RVVM1QI (unspec:RVVMF8BI [
                    (const_vector:RVVMF8BI repeat [
                            (const_int 1 [0x1])
                        ])
                    (reg:DI 145)
                    (const_int 2 [0x2]) repeated x2
                    (const_int 0 [0])
                    (reg:SI 66 vl)
                    (reg:SI 67 vtype)
                ] UNSPEC_VPREDICATE)
            (mem:RVVM1QI (reg:DI 144) [0  S[16, 16] A8])
            (unspec:RVVM1QI [
                    (reg:SI 0 zero)
                ] UNSPEC_VUNDEF))) "/app/example.c":7:23 -1
     (nil))

That seems complex.=
