            Bug ID: 48883
           Summary: [AMDGPU][MC][GFX10] Incorrect error position for
                    missing dim modifier
           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

Missing value of dim modifier may result in an incorrect error position.

For example, assembling an instruction

    image_atomic_xor v4, v32, s[96:103] dmask:0x1 dim:, glc

results in the following error message:

    error: failed parsing operand
    image_atomic_xor v4, v32, s[96:103] dmask:0x1 dim:, glc
                                                        ^
