const because they affect the file system, not the Path object.

because LLVM should be agnostic to the needs of specific front ends.

createTemporaryFile semantics where it doesn't create a fully unique name
if the basename doesn't exist. This functionality is now optionally
provided by the boolean reuse_current parameter to createTemporaryFile and
makeUnique. The default values differ because of the way these functions
are used in LLVM.

llvm-svn: 18961

* Fix implementation and documentation about LLVMGCCDIR/bytecode-libs
* Add the makeUnique method, replacement for getUniqueFilename in Support.
* Add the sys::CopyFile function, replacement for CopyFile in Support.
* Move GetLLVMConfigDir() into generic code area since its generic.

Implement three new functions to allow setting access/permission bits on
the file referenced by a path. The makeReadable and makeExecutable methods
replace the FileUtilities MakeFileReadable and MakeFileExecutable
functions. The makeWritable function is new and provided for consistency
since Path has a writable() method.

properly (examples: "", ".", "a").

llvm-svn: 18883

* Correct the std::string constructor to take a const reference.

llvm-svn: 18877

* Remove IsLibrary and GetLibraryPath, replaced by FindLibrary in ../Path.cpp \
* Implement GetSystemLibraryPaths and GetBytecodeLibraryPaths, instead of the \
  GetSystemLibraryPath1 and GetSystemLibraryPath2 methods

* Don't use variable length arrays (replaced with alloca)

llvm-svn: 17901

* Clean up the StatusInfo constructor to construct all members and give
  them reasonable values.
* Get rid of the Vector typedef and make the interface to
  getDirectoryContent use a std::set instead of a std::vector so the dir
  content is sorted.
* Make the getStatusInfo method const and not return a useless boolean.

returnn false if the file doesn't exist rather than throw ane exception.

llvm-svn: 17809

* Implement getDirectoryContents * Implement getStatusInfo * Implement setStatusInfo * Implement renameFile

llvm-svn: 17780

* Implement createTemporaryFile for mkstemp(3) functionality
* Fix isBytecodeFile to accept llvc magic # (compressed) as bytecode.

path and suffix to leave basename, and getting the DLL suffix.

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/.

note individually but these essence of it is to not derive from
std::string, clarify the interface, and provide better documentation.
There is now also (untested) implementations for AIX, Darwin, and SunOS.
