Renamed functions that were all lower-case.
Moved functions from util.cpp into linker.cpp or gccld.cpp.
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.

With this option, gccld links the program into LLVM bytecode and a native code
binary. This allows llvmgcc to correctly tell GNU configure scripts when
things aren't defined properly (because the native link will fail).

Switch Interpreter and JIT's "run" methods to take a Function and a vector of
GenericValues.
Move (almost all of) the stuff that constructs a canonical call to main()
into lli (new methods "callAsMain", "makeStringVector").
Nuke getCurrentExecutablePath(), enableTracing(), getCurrentFunction(),
isStopped(), and many dead decls from interpreter.
Add linux strdup() support to interpreter.
Make interpreter's atexit handler runner and JIT's runAtExitHandlers() look
more alike, in preparation for refactoring.
atexit() is spelled "atexit", not "at_exit".

Mung some comments.

Removed the use of sys/types.h and sys/stat.h.

file existance. This requires less header files and might even be a tad bit
faster.

* 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

* 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

* 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.

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.

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.

* 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.

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 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.)
