Extended Description
According with AMD docs, the following opcodes should support op_sel:
- v_alignbit_b32
- v_alignbyte_b32
- v_interp_p2_f16
Also there are 'legacy' opcodes:
- v_mad_legacy_f16
- v_mad_legacy_i16
- v_mad_legacy_u16
- v_fma_legacy_f16
- v_interp_p2_legacy_f16
- v_div_fixup_legacy_f16
These are labelled in SP3 as accepting op_sel; AMD docs says nothing about that. I believe these legacy opcodes should not support op_sel because this feature is not in GFX8.
