miscompilation. This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.

through to gcc when its being used as a linker. This allows -L and -l
(and any other) options to be added so that non-complete bytecode files
can be processed with bugpoint. The -Xlinker option can be added as many
times as needed.

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:
makeReadable -> makeReadableOnDisk
makeWriteable -> makeWriteableOnDisk
makeExecutable -> makeExecutableOnDisk
setStatusInfo -> setStatusInfoOnDisk
createDirectory -> createDirectoryOnDisk
createFile -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy -> eraseFromDisk
rename -> renamePathOnDisk
These changes pass the Linux Deja Gnu tests.

Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:
appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set
Changes pass Dejagnu and llvm-test/SingleSource tests.

* removeFile() -> sys::Path::destroyFile()
* remove extraneous toString() calls
* convert local variables representing path names from std::string to
sys::Path
* Use sys::Path objects with FileRemove instead of std::string
* Use sys::Path methods for construction of path names

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

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.

* Added DEBUG() statements to print out parameters passed to executing programs
* Actually ADD parameters to a program running via the JIT (using vector<char*>)
llvm-svn: 7433
* 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
llvm-svn: 7364
* 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.
