           Summary: bugpoint erroneously assumes exit code 1 is bad by
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: bugpoint
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nicholas at mxc.ca
                CC: resistor at mac.com, llvmbugs at cs.uiuc.edu

Try bugpoint'ing spiff some time. It happens to trigger this code in

  // If we're checking the program exit code, assume anything nonzero is bad.
  if (CheckProgramExitCode && ProgramExitedNonzero) {
    if (RemoveBitcode)
    return true;

which is really horrible because ProgramExitedNonzero is true even when running
the native version, but bugpoint doesn't check for that. CheckProgramExitCode
is on by default, but you can pass in -check-exit-code=false which makes it

I think with the advent of -append-exit-code, this check can just be removed,
or at least changed somehow. I'm not really sure up front what to do about it.
