This implementation is no longer needed, its been merged to Unix/Path.cpp since
there is such little variation between the platforms.

llvm-svn: 19133

Use the LLVM_ON_UNIX and LLVM_ON_WIN32 #defines to include the implementation
instead of relying upon the "platform" link

is now implemented via ltdl.cpp which has its own way of dealing with
the different platforms.

a function call at the core of the loop inline and removing unused
stack variables from an often called function. This doesn't improve things
much, the real saving will be by reducing the number of calls to this
function (100K+ when linking kimwitu++).

Include local FDHandle.h file now that FDHandle is local to this library
and not in lib/System/FileUtilities.

llvm-svn: 19108

FDHandle class (non-portable) moved here from lib/Support/FileUtilities

llvm-svn: 19107

Move non-portable FDHandle class to its only user: lib/Debugger

Remove unix specific code (use of errno and read) from the reader.

* 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

* llvm/Config/alloca.h already #includes config.h
* Minor readability/stylistic changes

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.
