            Bug ID: 48295
           Summary: [AMDGPU][MC] Misleading diagnostics message for
                    operands specified as expr/macro
           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

Some operands may be specified as either a 'macro' or an expression. Assembler
may issue a misleading error message for such operands stating that only an
expression is expected.

An example:

    ds_swizzle_b32 v8, v2 offset:typo(QUAD_PERM, 0, 1, 2, 3)

Error message:

    expected absolute expression
