            Bug ID: 22743
           Summary: UNREACHABLE executed at X86Disassembler.cpp:380!
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

On recent trunk:

--------------------------------------------------
$ echo '98 129 165 88 194 227 127' | llvm-mc -disassemble
-triple=x86_64-apple-darwin9
        .section        __TEXT,__text,regular,pure_instructions
unexpected opcode
UNREACHABLE executed at
/home/sliedes/projects/llvm/llvm.src/lib/Target/X86/Disassembler/X86Disassembler.cpp:380!
--------------------------------------------------

This is probably not any valid instruction (I haven't checked and have no
reason to think it is), however it probably shouldn't crash.
