        <pre>In contrast with other 'movrels' opcodes, v_movrelsd_b32 accepts an
sgpr/constant as src0. This is incorrect. These operands are not supported by
SP3 for v_movrelsd_b32.

Compare:

    v_movrels_b32 v0, v0  // ok
    v_movrels_b32 v0, s0  // error
    v_movrels_b32 v0, 0   // error

    v_movrelsd_b32 v0, v0  // ok
    v_movrelsd_b32 v0, s0  // ok (but should trigger an error)
    v_movrelsd_b32 v0, 0   // ok (but should trigger an error)</pre>
