 can be used to debug three types of failures: optimizer crashes, miscompilations

 **--additional-so** *library*
 
  Load the dynamic shared object *library* into the test program whenever it is
  run.  This is useful if you are debugging programs which depend on non-LLVM
  libraries (such as the X or curses libraries) to run.

-
 **--append-exit-code**\ =\ *{true,false}*
 
  Append the test programs exit code to the output file so that a change in exit
  code is considered a test failure. Defaults to false.

 **--args** *program args*
 
- Pass all arguments specified after -args to the test program whenever it runs.

  Pass all arguments specified after **--safe-tool-args** to the "safe" execution
  tool.

  Use valgrind to find faults in the optimization phase. This will allow
  bugpoint to find otherwise asymptomatic problems caused by memory
  mis-management.
