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.

cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts. In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.
This patch unifies all of the sizes to use size_t instead.

portability, the --track-space option was inadvertently ignored. This patch
fixes that so that sys::Process::GetMallocUsage() is only invoked if the
--track-spaces option is given. Apparently the mallinfo() call that
GetMallocUsage() uses is *very* slow, especially when processing very large
modules like projects/llvm-test/MultiSource/Applications/kimwitu++.
llvm-svn: 19163
* Move system dependent implementation out of this file.
* Make implementation use sys::Process::GetMallocUsage where necessary.
* Make implementation use sys::Process::GetTimeUsage where necessary.
llvm-svn: 19053
* Pass sys::Path instead of std::string for paths
* Correct the types of arguments passed to RunProgramWithTimeout due to its
interface using sys::Path instead of std::string
* Replace "/dev/null" (not portable) with empty string which
sys::Program::ExecuteAndWait recognizes as "redirect to bit bucket"
llvm-svn: 19041
* Remove unneeded header files.
* Move RedirectFD static function to lib/System/Unix/Program.cpp
* Delete RunProgramWithTimeout, now implemented by
sys::Program::ExecuteAndWait. RunProgramWithTimeout is now a convenience func.
llvm-svn: 19040
* Make the OutputC and OutputAsm functions work with sys::Path for the output
file name instead of using std::string.
* Get rid of extraneous "toString" calls.
* Change "removeFile" to sys::Path::destroyFile()
llvm-svn: 19000
* 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
llvm-svn: 18999
* Remove isExecutable as its now implemented by sys::Path::executable
* Make FindExecutable a thin veneer over sys::Program::FindProgramByName.

Remove AllocateRWXMemory as it is not used any more in LLVM. The function
has been replaced with sys::Memory::AllocateRWX several months ago.
llvm-svn: 18912
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.
