3b624625e7 Ignore intrinsic functions -- don't mangle their names or rewrite calls to them.

be6bf5668c CodeGeneratorBug.cpp:
* Temporarily externing InputArgv to print it out for the benefit of LLI command
  needed to reproduce the result.
* Print out the list of functions currently being tested
* ListReducer now returns a bool if there was a failure, so test for it

ListReducer.h:
* Handle the case where there is no problem by returning true if failure is
  found. Also correctly handles the case when there is only 1 pass/function.

Miscompilation.cpp:
* ListReducer now returns a bool if there was a failure, so test for it

9d679cbc6c * Moved InputArgv out of anonymous scope to be extern'd in another file.
* Added DEBUG() statements to print out parameters passed to executing programs
* Actually ADD parameters to a program running via the JIT (using vector<char*>)

5d5bc7b90c Revert change: default architecture is never set, it is guessed from input
bytecode file. This means that LLC on X86 will compile to Sparc assembly given a
64-bit input bytecode file...

c1e39ee659 Implemented cleanups as suggested by Chris:
* Use Module::getNamedFunction() to delete "main" instead of using a loop
* Compare function pointers instead of function names to determine equivalence
* Simplified creation of a 2-element vector containing zeroes
* Manually performed LICM on code
* Added an abort() in case a function we're considering occurs in something that
  is not an instruction
* Use DEBUG() around code sections instead of just in a statement in a loop,
  because GCC's DCE may not be good enough to completely remove it in a release
  build
* Print out a command that can be directly copied-and-pasted to re-execute
* Instead of just checking if a symbol begins with a dot and fixing it
  accordingly, use Mangler and fix all the problems (invalid chars in C symbol
  names) entirely
* The new `main' function has external linkage

91eabc13d3 BugDriver.h:
* Added method to query if BugDriver is executing the JIT currently.
  This provides the ability in adding code that is conditionally executed in
  codegen debugging phase.

CodeGeneratorBug.cpp:
* Delete test functions from the Safe module
* Code conditionally added when debugging the JIT:
  use the lazy resolver function added to Emitter.cpp to get function pointer
  by name. When compiled into an .so, this is the only way to get a pointer to
  an external function
* Added a symbol disambiguator which will keep symbols uniquely named across
  modules
* Delete generated files by default
* The function `main' *must* stay in the .bc file for the JIT, but that prevents
  debugging it alone. This patch makes the old `main' become `old_main' and adds
  a new function named `main' which just calls the original with the same
  parameters, thereby keeping functionality the same.

ExecutionDriver.cpp:
* Returned to getting unique filenames
* Simplified code choosing between using and not using shared library option

a259c9be2a Made a bunch of cleanups, as per Chris' recommendations:
* Removed unused global and member variables
* Fixed comments (CodeGeneratorBug.cpp)
* Check for possibly failing GCC::create() and CBE::create()
* Remove generated files after diffing the output (e.g., shared object)
* Instead of using std::for_each, use explicit loops as std::for_each may
  duplicate the functor, and ours carries state
* Changed member var from cl::opt<std::string> to just std::string
* Fixed doxygen comments
* Fixed string comparisons to use [ str.empty() ] instead of [ str == "" ]
* Cache instances of CBE and GCC in BugDriver across compilations and executions
  while testing tools.

5073336cd4 Major addition to bugpoint: ability to debug code generators (LLC and LLI).
The C backend is assumed correct and is used to generate shared objects to be
loaded by the other two code generators.

LLC debugging should be functional now, LLI needs a few more additions to work,
the major one is renaming of external functions to call the JIT lazy function
resolver.

Bugpoint now has a command-line switch -mode with options 'compile' and
'codegen' to debug appropriate portions of tools.

ExecutionDriver.cpp: Added implementations of AbstractInterpreter for LLC and
GCC, broke out common code within other tools, and added ability to generate C
code with CBE individually, without executing the program, and the GCC tool can
generate executables shared objects or executables.

If no reference output is specified to Bugpoint, it will be generated with CBE,
because it is already assumed to be correct for the purposes of debugging using
this method. As a result, many functions now accept as an optional parameter a
shared object to be loaded in, if specified.

fcf2be75ec Initialize the target architecture based on compiler defines, so if compiled on
x86 or Sparc, LLC will automatically default to that platform, no guessing
required. On another platform, it will default to `noarch' and will have to
guess which architecture to compile to.

82742916f3 * If compiling on X86 or Sparc, automagically enable the JIT for that arch
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will
  force the inclusion of that JIT on a different architecture
* If neither JIT is enabled (e.g., compiling on a different architecture), the
  -march option will not be available to LLI.
* As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit
  faster by not including the x86 library.

 Remove support for running arbitrary optimization passes. Use opt instead.
 Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
