            Bug ID: 49645
           Summary: [AMDGPU][MC][GFX10] v_pk_fmac_f16 is decoded with _e32
                    suffix
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            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

This is a VOP2 only opcode, so _e32 suffix is not valid.

Test:

    0x01,0x05,0xfe,0x79

Output:

    v_pk_fmac_f16_e32 v255, v1, v2
