<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>
