[need example] findFunction

Related to .llvm
 [done] makeRFunction()
 [ignore] run()

Context
 getContext(), getGlobalContext()

[ignore] llvmLoadDLL
[done] llvmAddSymbol

[finish] findFunction to get address of routine in an ExecutionEngine and can pass that to 
  a regular C routine.
  Example of compiling a routine and passing that to a routine.
     sort is one example
     numerical optimization

% Mention in exporting/importing IR code with other languages.
I/O of code
{write,read}BitCode, parseIR, parseAssembly

Pass manager
 getPassManager

 addPass, addAnalysisPasses

 addPassesToEmitFile, stringRawOstream, rawFDOstream, formattedRawOstream

Different targets:
  getLLVMTargets
  getTargetTriple 
  {g,s}etDataLayout
  lookupTarget
  targetLibraryInfo
  InitializeNVPTXTarget, InitializeCppBackendTarget


System-level commands
[done] llvmVersion
 InitializeNativeTarget - should this be in back-ends

setAlignment

Explain module instance is specific to an execution engine


Module
