//===- ExecutionDriver.cpp - Allow execution of LLVM program --------------===//

//
|

// This file contains code used to execute the program utilizing one of the
|
|
// various ways of running LLVM bytecode.

BUGPOINT NOTES:
|
|
|
|
1. Bugpoint should not leave any files behind if the program works properly
|
|
2. There should be an option to specify the program name, which specifies a
|
|
unique string to put into output files. This allows operation in the
|
|
SingleSource directory, e.g. default to the first input filename.
