           Summary: Function deleted in an error
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: asl at math.spbu.ru


Consider attached testcase.

Run llc via "./llc -enable-eh". You'll see, that _Z17handle_unexpected function
is dropped from the generated assembly. This is horrible bad :(. Everything is
ok with "-fast". Almost surely the problem is due to "unreachable" inst in the
"invcont16" BB (note, that cxa_throw will always throw, so the code is correct).
