imo no need to test this, ll tests should cover it, can remove. If you really want to keep it name is wrong, legalize tests test Legalizer, we don't really test amdgpu-regbanklegalize mir only, similar old tests are named regbankselect-xyz but we do amdgpu-regbankselect + amdgpu-regbanklegalize there
