            Bug ID: 44582
           Summary: [AMDGPU][MC][GFX908] 'glc' is not supported for
                    global_atomic_add_f32 and global_atomic_pk_add_f16
           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

It is not clear why glc modifier is not supported for these opcodes:

      global_atomic_add_f32 v0, v[1:2], v2, off offset:-1 glc // error
      global_atomic_add_f32     v[1:2], v2, off offset:-1     // ok

sp3 assembler supports this modifier:

      global_atomic_add_f32 v0, v[0:1], v0, s[0:1] glc // sp3: ok
