           Summary: [AMDGPU][MC][GFX9] Enable inline constants for SDWA
                    operands
           Product: libraries
           Version: trunk

          Severity: enhancement
          Priority: P

SDWA should enable inline constants as operands. SP3 seems to support these.

An example of a valid test:

v_sub_f32_sdwa v5, -4.0, v2 dst_sel:DWORD dst_unused:UNUSED_PAD src0_sel:DWORD
src1_sel:DWORD
