Pull in r217410 from upstream llvm trunk (by Bob Wilson):
Set trunc store action to Expand for all X86 targets.
When compiling without SSE2, isTruncStoreLegal(F64, F32) would return
Legal, whereas with SSE2 it would return Expand. And since the Target
doesn't seem to actually handle a truncstore for double -> float, it
would just output a store of a full double in the space for a float
hence overwriting other bits on the stack.
Patch by Luqman Aden!
This should fix clang -O0 on i386 assigning garbage to floats, in
certain scenarios.

In r253839 the default behaviour of ld(1) was changed such that all
libraries that need to be linked into an executable or library have to be
listed on the command line explicitly. This commit fixes a bug in ld(1)
where it would scan dependencies of the libraries on the command line and
link them if needed if they were also found in ld.so.cache.
The important bit of the patch is the initialisation of needed.by such that
libraries found by scanning dependencies are marked as such and not used in
the link.
The patch is a backport of binutils git commit

Remove leading '/' from hardlink name when removing them from the

hardlinks to extracted files.
r266650:
Change libatf-c and libatf-c++ to be private libraries.
We should not be leaking these interfaces to the outside world given
that it's much easier for third-party components to use the devel/atf
package from ports.
As a side-effect, we can also drop the ATF pkgconfig and aclocal files
from the base system. Nothing in the base system needs these, and it
was quite ugly to have to get them installed only so that a few ports
could build. The offending ports have been fixed to depend on
devel/atf explicitly.

r267172:
Homogenize libatf-* version numbers with upstream.
The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected. This is just confusing and bound to cause
problems down the road.
Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default. However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.

r269806:
Fix too long (seed length >12 chars) challenge handling.
1) " ext" length should be included into OPIE_CHALLENGE_MAX (as all places
of opie code expects that).
2) Overflow check in challenge.c is off by 1 even with corrected
OPIE_CHALLENGE_MAX
3) When fallback to randomchallenge() happens and rval is 0 (i.e.
challenge is too long), its value should be set to error state too.
To demonstrate the bug, run opiepasswd with valid seed:
opiepasswd -s 1234567890123456
and notice that it falls back to randomchallenge() (i.e. no
1234567890123456 in the prompt).

We previously sent SIGKILL to the debuggee in DoDestroy, but did not
actually detach or kill via ptrace. It seems that this somehow didn't
matter on Linux, but did on FreeBSD.
This would happen when quitting LLDB while stopped at a breakpoint, for
example. The debuggee remained stopped in ptrace (with the signal
either pending or lost). After a timeout of a second or two LLDB exits,
which caused the debuggee to resume and dump core from an unhandled
SIGTRAP.
BringProcessIntoLimbo is a poorly named wrapper for ptrace(PT_KILL)
which is the desired behaviour from DoDestroy.

Implement a new -fstandalone-debug option. rdar://problem/15685848
It controls everything that -flimit-debug-info used to, plus the
vtable type optimization. The old -fno-limit-debug-info option is now an
alias to -fstandalone-debug and vice versa.
Standalone is the default on Darwin until dtrace is updated to work with
non-standalone debug info (rdar://problem/15758808).
Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind
because NoStandaloneDebugInfo sounded even more confusing.

Pull in r211627 from upstream llvm trunk (by Bill Schmidt):
[PPC64] Fix PR20071 (fctiduz generated for targets lacking that
instruction)
PR20071 identifies a problem in PowerPC's fast-isel implementation
for floating-point conversion to integer. The fctiduz instruction
was added in Power ISA 2.06 (i.e., Power7 and later). However, this
instruction is being generated regardless of which 64-bit PowerPC
target is selected.
The intent is for fast-isel to punt to DAG selection when this
instruction is not available. This patch implements that change.
For testing purposes, the existing fast-isel-conversion.ll test adds
a RUN line for -mcpu=970 and tests for the expected code generation.
Additionally, the existing test fast-isel-conversion-p5.ll was found
to be incorrectly expecting the unavailable instruction to be
generated. I've removed these test variants since we have adequate
coverage in fast-isel-conversion.ll.
This is needed to compile clang with debug+asserts on older powerpc64
and ppc970 targets.
