            Bug ID: 49447
           Summary: [AMDGPU][GFX9][DOC] Incorrect description of SDWA src0
           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

Description states that SDWA src0 may be a literal or lds_direct. This is
incorrect, these operands are not supported for SDWA.
