Craig Topper 2617dccea2 [C++11] More 'nullptr' conversion. In some cases just using a boolean check instead of comparing to nullptr.

Ahmed Charles 56440fd820 Replace OwningPtr<T> with std::unique_ptr<T>.
This compiles with no changes to clang/lld/lldb with MSVC and includes
overloads to various functions which are used by those projects and llvm
which have OwningPtr's as parameters. This should allow out of tree
projects some time to move. There are also no changes to libs/Target,
which should help out of tree targets have time to move, if necessary.

Benjamin Kramer 17388a61b2 Revert "[C++11] Replace LLVM atomics with std::atomic."
Breaks the MSVC build.

Benjamin Kramer 0b6eb591a4 [C++11] Replace LLVM atomics with std::atomic.
With C++11 we finally have a standardized way to specify atomic operations. Use
them to replace the existing custom implemention. Sadly the translation is not
entirely trivial as std::atomic allows more fine-grained control over the
atomicity. I tried to preserve the old semantics as well as possible.

Rafael Espindola 90c7f1cc16 Replace the F_Binary flag with a F_Text one.
After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

Rafael Espindola 6d35481c94 Add a wrapper for open.
This centralizes the handling of O_BINARY and opens the way for hiding more
differences (like how open behaves with directories).

Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Dan Gohman 6e681a5fbe Give NamedRegionTimer an Enabled flag, allowing all its clients to
switch from this:

  if (TimePassesIsEnabled) {
    NamedRegionTimer T(Name, GroupName);
    do_something();
  } else {
    do_something(); // duplicate the code, this time without a timer!
  }

to this:

  {
    NamedRegionTimer T(Name, GroupName, TimePassesIsEnabled);
    do_something();
  }

Chris Lattner 9a608d248e change TimerGroup to keep a linked list of active timers
instead of just a count of them, and refactor the guts of
report printing out of removeTimer into its own method.

Chris Lattner 09a4074869 remove support for per-time peak memory tracking, this
isn't used by anyone and is better exposed as a non-per-timer 
thing.  Also, stop including System/Mutex.h in Timer.h

Chris Lattner b355db7877 various timer fixes: move operator= out of line,
eliminate the per-timer lock (timers should be 
externally locked if needed), the info-output-stream
can never be dbgs(), so drop the check.  Make some
stuff private.

Owen Anderson e9b1beb543 Make timers threadsafe again. This isn't quite as nice as I'd hoped (it uses locking rather than atomic arithmetic),
but should work on all the platforms we care about.

I might revisit this if a totally awesome way to do it occurs to me.

Dan Gohman 5ceb8b676c Append to the ActiveTimers std::vector before looking at the timer instead
of after, so that any reallocation it does doesn't get counted for the pass
being timed.  This probably doesn't account for a timing discrepancy I was
looking into, but I'm fixing it anyway.
