04b8fe6b33 Add check-exit-code option, defaulting to true. 
Add ProgramExitedNonzero argument to executeProgram(), and make it
tell its caller whether the program exited nonzero.

Move executeProgramWithCBE() out of line, to ExecutionDriver.cpp, and remove
its extra arguments which are always defaulted.  Make it turn off
check-exit-code if the program exits nonzero while generating a reference
output.

Make diffProgram() assume that any nonzero exit code is a failure, if
check-exit-code is turned on.

15ea2aa0ff Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas. 
This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

207cf0a20d Modified the logic so that library objects with main() are only linked in 
if the program currently has main undefined.

8f95f1d2ca Modified the linker so that it always links in an object from an archive 
that defines the symbol "main."  This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.

There is probably a more correct way to do this, but this works for now.

4f8c392983 Shorten and correct some function-header comments. 
Make "verbose" output MUCH nicer. Now it tells you when you are linking a
bytecode file, or an archive, and whether it's because you called it by name,
or because you gave it a -l option, and it says "Trying" before it takes
action and prints a message in the past tense afterwards.

Make LinkFiles not skip the first file in Files.

Make LinkFiles warn you if it can't find a file and LLVM_LIB_SEARCH_PATH is
unset.

62b495bd5c I hate it when bugpoint is all ready to give me a bytecode file, then crashes 
in final cleanups.  Then you had to run the whole mess again with
-disable-final-cleanups.

This makes bugpoint run the cleanups in a protected environment so that if
they crash, bugpoint itself doesn't crash.  This makes things much happier,
implements a FIXME, and gets rid of YABPO (yet another bugpoint option).

Removed util.h and created gccld.h.
Refactored the linker functionality in linker.cpp so that it is easier to
follow, easier to modify, and it's library/object file search behavior is
easier to understand and document.
Added code to include library paths when doing native linking, but this
causes problems and is currently #ifdef'd out.

passed into main().  This may (or may not) be more portable, but it looks
nicer.
Added functions to copy the environment array and modify the copy, thus
preserving the environment.
Switched from using system() to using ExecWait().
The code now removes the assembly file generated when using the -native option.
Fixed the remove_env() function: The previous revision truncated the
environment variable list.  This version just zaps the variable as intended.

  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

844d79f8f5 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.

* 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.

e98a7e97d9 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.

582cf5be31 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.

009e42dd43 * 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.
