Unify default construction of error_code uses on this idiom so that users don't
feel compelled to make static globals for naming convenience. (unfortunately I
couldn't make the original ctor private as some APIs don't return their result,
instead using an out parameter (that makes sense to default construct) - which
is a bit of a pity. I did, however, find/fix some cases of unnecessary default
construction of error_code before I hit the unfixable cases)

start of a filename, not a filename+length. All clients can produce a
null terminated name, and the system api's require null terminated
strings anyway.

not an mmapped file. This more closely matches its requirements and
provides an implicitly null terminated buffer, something this
routine had to emulate itself before.

Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

Final remove of exception handling from this file. lib/System can no longer
throw exceptions so there's no need for try/catch blocks here.

Adjust users of MappedFile to its new non-throwing interface. Note that in
most cases the lazy step of just throwing after a call to MappedFile was
installed. This was done in the name of incremental changes. Getting rid of
the new throw statements will take adjustment of interfaces and propagation
of errors to higher levels. Those changes will come in subsequent patches.

instead of throwing an exception. This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

handling zero length files a little more intelligently. If both files are
zero length then we return 0 (true) indicating a match. If only one of the
files is zero length then we return 1 (false) indicating that the files
differ. If the files don't agree in length then they can't match so we
skip the first loop that looks for a quick match.

* Remove the "removeFile" function, now implemented by the
sys::Path::destroyFile method.
* Make the FileRemove work with a sys::Path instead of a std::string

Remove the MakeFileReadable and MakeFileExecutable functions which are no
longer present in LLVM. They have been replaced with the sys::Path methods
makeReadable and makeExecutable, respectively.
llvm-svn: 18910
The ReadFileIntoAddressSpace and UnmapFileFromAddressSpace functions are no
longer used by LLVM. Remove them. Replacement functionality for both
functions is now encapsulated in the sys::MappedFile class.
llvm-svn: 18903
The getFileTimestamp and getFileSize functions have been removed from \
FileUtilities.{h,cpp}. They are replaced by Path::getTimestamp and \
Path::getSize,respectively.
llvm-svn: 18892
into memor. This is just a reminder that the ReadFileIntoAddressSpace
function needs to be properly converted to lib/System and implemented via
read/write if there's no mmap of file support.

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/.
