            Bug ID: 49643
           Summary: [AMDGPU][MC][GFX90a] v_mul_legacy_f32 is decoded with
                    _e64 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

V_MUL_LEGACY_F32 has been moved from VOP2 to VOP3, so _e64 suffix is not valid.

Test:

    0x05,0x00,0xa1,0xd2,0xff,0x05,0x02,0x00

Output:

    v_mul_legacy_f32_e64 v5, v255, v2
