            Bug ID: 32927
           Summary: [mc] Disassembler incorrectly appends "_e32" suffix to
                    v_madak/v_madmk instructions
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: AMDGPU
          Assignee: unassignedbugs at nondot.org
          Reporter: dpreobrazhensky at luxoft.com
                CC: llvm-bugs at lists.llvm.org

v_madak/v_madmk instructions cannot be promoted to VOP3, so "_e32" suffix
should not be used.

Examples of failed tests:


Disassembled as

v_madak_f16_e32 v5, 0, v2, 0x1121
v_madak_f32_e32 v5, 0, v2, 0x11213141
v_madmk_f16_e32 v5, 0, 0x1121, v3
v_madmk_f32_e32 v5, 0, 0x11213141, v3
