            Bug ID: 36876
           Summary: IRET instruction has a different naming convention to
                    RET/LRET
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: X86
          Assignee: unassignedbugs at nondot.org
          Reporter: llvm-dev at redking.me.uk
                CC: craig.topper at gmail.com, llvm-bugs at lists.llvm.org

Found during fixing models for D44687:

RET/LRET use the naming pattern:
RET(L|Q|W)
LRET(L|Q|W)


But IRET uses the naming pattern:
IRET(16|32|64)

Do we want to standardize this?

The IRET mnemonic is IRETW/IRETD/IRETQ so it seems a better match, and would
have helped the AMD guys who wrote the Znver1 entries assuming it.
