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

llvm-svn: 19064

system dependent functionality 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

llvm-svn: 19050

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.
