            Bug ID: 36001
           Summary: [AMDGPU][MC] r128 modifier of image instructions
                    should affect SRSRC size
           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

r128 modifier specifies 128-bit resource size when present (256-bit by
default). This modifier should affect SRSRC size.

An example of a failed test:

    image_atomic_add v5, v1, s[8:11] dmask:0x1 r128

The instruction shown above is how SP3 disassembles the code.

Note: r128 is removed in GFX9 so this issue has low priority
