George Rimar 4c2ae3a171 Return back the zero parameter of aggregate initialization in OutputSectionFactory::lookup().
That was removed in r266304, but leads to warnings by Clang.
Thanks to Rafael Espíndola for pointing on that.

Though I think change was legal from point of C++.

Ed Maste fe2b70637c [sanitizer] remove FreeBSD PS_STRINGS fallback
The PS_STRINGS constant can easily be incorrect with mismatched
kernel/userland - e.g. when building i386 sanitizers on FreeBSD/amd64
with -m32. The kern.ps_strings sysctl was introduced over 20 years ago
as the supported way to fetch the environment and argument string
addresses from the kernel, so the fallback is never used.

Marcin Koscielnicki c8dda336bb [sanitizer] [SystemZ] Abort if the kernel might be vulnerable to CVE-2016-2143.
In short, CVE-2016-2143 will crash the machine if a process uses both >4TB
virtual addresses and fork().  ASan, TSan, and MSan will, by necessity, map
a sizable chunk of virtual address space, which is much larger than 4TB.
Even worse, sanitizers will always use fork() for llvm-symbolizer when a bug
is detected.  Disable all three by aborting on process initialization if
the running kernel version is not known to contain a fix.

Unfortunately, there's no reliable way to detect the fix without crashing
the kernel.  So, we rely on whitelisting - I've included a list of upstream
kernel versions that will work.  In case someone uses a distribution kernel
or applied the fix themselves, an override switch is also included.

Pavel Labath a212c58db0 FileSpec: make matching separator-agnostic again
Summary:
In D18689, I removed the call to Normalize() in FileSpec::SetFile, because it no longer seemed
needed, and it resolved a quirk in the FileSpec API (spec.GetCString() returnes a path with
backslashes, but spec.GetDirectory().GetCString() has forward slashes). This turned out to be a
problem because we would consider paths with different separators as different (which led to
unresolved breakpoints for instance).

Here, I am putting back in the call to Normalize() and adding a unittest for FileSpec::Equal. I
am commenting out the GetDirectory unittests until we figure out the what is the expected
behaviour here.

Kuba Brecka 173c690a61 [tsan] Fix size reporting for OS X zone allocator with 0-sized allocations
The custom zone implementation for OS X must not return 0 (even for 0-sized allocations). Returning 0 indicates that the pointer doesn't belong to the zone. This can break existing applications. The underlaying allocator allocates 1 byte for 0-sized allocations anyway, so returning 1 in this case is okay.

David Majnemer 0f26b0aeb4 [CodeGen] Teach LLVM how to lower @llvm.{min,max}num to {MIN,MAX}NAN
The behavior of {MIN,MAX}NAN differs from that of {MIN,MAX}NUM when only
one of the inputs is NaN: -NUM will return the non-NaN argument while
-NAN would return NaN.

It is desirable to lower to @llvm.{min,max}num to -NAN if they don't
have a native instruction for -NUM.  Notably, ARMv7 NEON's vmin has the
-NAN semantics.

N.B.  Of course, it is only safe to do this if the intrinsic call is
marked nnan.

Reid Kleckner 9305fd1f86 [CodeGen] Avoid ctor/dtor boilerplate with some C++11
Non-owning pointers that cache LLVM types and constants can use
'nullptr' default member initializers so that we don't need to mention
them in the constructor initializer list.

Owning pointers should use std::unique_ptr so that we don't need to
manually delete them in the destructor. They also don't need to be
mentioned in the constructor at that point.

Tim Northover 5c02f9ad28 ARM: override cost function to re-enable ConstantHoisting (& fix it).
At some point, ARM stopped getting any benefit from ConstantHoisting because
the pass called a different variant of getIntImmCost. Reimplementing the
correct variant revealed some problems, however:

  + ConstantHoisting was modifying switch statements. This is simply invalid,
    the cases must remain integer constants no matter the notional cost.
  + ConstantHoisting was mangling alloca instructions in the entry block. These
    should be handled by FrameLowering, so constants actually have a cost of 0.
    Worse, the resulting bitcasts meant they became dynamic allocas.
