            Bug ID: 39315
           Summary: [AMDGPU][MC][DISASSEMBLER][GFX8+] Missing _e32/_e64
                    suffices for v_nop and v_clrexcp instructions
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: AMDGPU
          Assignee: unassignedbugs at nondot.org

v_nop and v_clrexcp are VOP1 opcodes which can be promoted to VOP3. According
with our conventions, VOP1 versions should have _e32 suffix while VOP3 versions
should have _e64 suffix.

Currently disassembler does not append any suffices to there instructions.
