            Bug ID: 30829
           Summary: [mc][gfx8] No checks for ADDC/SUBB/V_CNDMASK source
                    operand restrictions
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: AMDGPU
          Assignee: artem.tamazov at amd.com

    Classification: Unclassified

SGPR, M0, EXEC or literal constant are not allowed for ADDC/SUBB/V_CNDMASK
instructions. Still assembler allows illegal encodings like:

v_addc_u32 v40, vcc, s49, 0, vcc
