Misha Brukman 0fd3172754 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.

Misha Brukman d792c9bb46 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.

Misha Brukman 63e14b5a4a 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.

Misha Brukman 7dee443c1c * 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.

Brian Gaeke cf8c4f5fe4 lib/Target/Sparc/Sparc.cpp:
Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
  the corresponding -disable-strip and -d options, over here to the SPARC
  target-specific bits of llc. Rename -d to -dump-asm.

tools/llc/Makefile:
 Reindent. Add x86 library so that llc compiles again.

tools/llc/llc.cpp:
 Remove support for running arbitrary optimization passes. Use opt instead.
 Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
  above.
 Allow user to select a backend (x86 or SPARC); default to guessing from
  the endianness/pointer size of the input bytecode file.
 Fix typos.

  static compilation.

Chris Lattner d9cc372613 Do not link in the Sparc JIT when building on X86. Eventually the sparc will not
link in the X86 JIT either, but this makes testing easier.

For some reason, the sparc JIT was breaking the X86 JIT when it was linked in. :(

Brian Gaeke 5bfa37f4df gccld.cpp:
Fix typo in header.
 Add IsArchive static method.
 Roll LoadLibraryFromDirectory() into LoadLibrary(), and factor
  LoadLibraryExactName() out of the result. Instead of treating the current
  directory specially, just insert it into LibPaths in the beginning of
  main().
 Make LoadLibrary() take a "search" flag that says whether to search for the
  correct library, or just trust that LibName is right.
 Make LinkLibrary() take a "search" flag, and pass it to LoadLibrary().
 Change the for-loop over InputFilenames to detect ar archives and link them
  in as libraries without searching.
 Change the for-loop over Libraries to explicitly turn on the "search" flag
  to LinkLibrary() that makes LoadLibrary() search for the correct library
  (i.e., when processing -lNAME options.)
