last file in LLVM to require the header. After ths commmit, our unistd.h

dependent behavior is now made through the lib/System interface.

llvm-svn: 19064

system dependent functionality has been moved to lib/System.

llvm-svn: 19063

as most system dependent behavior has been moved to lib/System.

* Implement GetMallocUsage to get usage of malloc heap
* Implement GetMemoryUsage to get total memory usage of process
* Implement GetTimeUsage to get elapsed/user/system time

llvm-svn: 19055

No need for Unix/SUS/Process.cpp any more, just ifdef it.

llvm-svn: 19054

* 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

* Add checks for sbrk and getpagesize functions
* Alphebetize the checks for functions

llvm-svn: 19052

* Add GetMallocUsage as a wrapper around mallinfo()
* Add GetTotalMemoryUsage to get approximate RSS size
* Add GetTimeUsage to get elapsed/system/user time

llvm-svn: 19051

This file is no longer needed as system dependent functions have been
encapsulated into lib/System.

llvm-svn: 19049

* llvm/Config/alloca.h already #includes config.h

* Support changes in sys::Program::ExecuteAndWait interface

llvm-svn: 19044

Move the functionality of RunProgramWithTimeout into the ExecuteAndWait
function: support a timeout and I/O redirects

llvm-svn: 19043

Add a needed include.

llvm-svn: 19042

* 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

Incorporate the abilities of RunPRogramWithTimeout into
sys::Program::ExecuteAndWait so that redirection and a timeout are optionally
supported.

llvm-svn: 19039

Turn path instance variables into sys::Path instead of std::string

llvm-svn: 19038

Replace RunProgramWithTimeout with an inline function that calls
sys::Program::ExecuteAndWait. This is now just a convenience function.

files from win32/* to platform/*, create one line files in platform that include the
corresponding file in win32.  This makes life much more enjoyable!

The cruel irony is that NTFS has hard links just like Unix, but there's no way to
get to them from the DOS prompt!
