Whitespace update for lint check by myself (Will). Otherwise code and comments by Peter Bergner, as previously seen on llvm-commits.
The following patch gets ASAN somewhat working on powerpc64le-linux.
It currently assumes the LE kernel uses 46-bit addressing, which is
true, but it doesn't solve the case for BE where it may be 44 or
46 bits. That can be fixed with a follow on patch.
There are some test suite fails even with this patch that I haven't had
time to solve yet, but this is better than the state it is in now.
The limited debugging of those test suite fails seems to show that the
address map for 46-bit addressing has changed and so we'll need to
modify the shadow memory location slightly. Again, that can be fixed
with a follow on patch.

We have to #define _WANT_RTENTRY to get struct rtentry, and add headers
that it depends on.
SIOCADDRT and SIOCDELRT also do not exist in FreeBSD 10.1 and were removed
in FreeBSD rev. 263203:
Garbage collect long time obsoleted (or never used) stuff from routing
API.

When compiling with -mfpu=vfpv3, those tests began to pass, like the others
with "Illegal Instruction" error, so removing the XFAIL from them should
get the bot green (and have more tests!).

Clang r219557 introduces libcalls to complex multiply/divide functions.
Since these functions are not available in iOS for arm64 devices, add them to
the static libraries.

This change fixes 2 issues in the fast unwinder from r217079:
* A crash if a frame pointer points below current stack head, but
inside the current thread stack limits. That memory may be
unmapped. A check for this was lost in r217079.
* The last valid stack frame (the first one with an invalid next
frame pointer) is always interpreted as a GCC layout frame. This
results in garbled last PC in the (expected) case when the last
frame has LLVM layout.

Updated the URL to reflect information on the problem as well as build the
case for ARM. This seems to be a wider problem, not ARM or PPC specific.
llvm-svn: 219680
Allows to specify the unwinder to use for CHECK failures. Previous behaviour
was to use the "fatal" unwinder.
As compiler-rt is built without frame pointers, only the slow unwinder
really makes sense here, and it is the default.

The current handling (manual execution of atexit callbacks)
is overly complex and leads to constant problems due to mutual ordering of callbacks.
Instead simply wrap callbacks into our wrapper to establish
the necessary synchronization.

This change adds UBSan check to upcasts. Namely, when we
perform derived-to-base conversion, we:
1) check that the pointer-to-derived has suitable alignment
and underlying storage, if this pointer is non-null.
2) if vptr-sanitizer is enabled, and we perform conversion to
virtual base, we check that pointer-to-derived has a matching vptr.
llvm-svn: 219642
to pass in an opt build.
The test case in question does show UBSan catching the error, but it
doesn't then successfully set the exit code of the program. I'll let the
UBSan folks sort out why. It should reproduce trivially with an
optimized build.

ASAN, UBSAN and profile tests that don't work with arm-linux-gnueabi and
android also don't work on armv7l-linux-gnueabihf. Some of the tests have
known causes, others not yet. In order to get a green bot, I'm disabling
those tests for now and will investigate when the priority rises.

We should check whether the compiler & linker support ARM64 before attempting
to build a version of compiler-rt for it. Otherwise things will go badly.

Makes sure ARM bots don't run AArch64 and vice-versa, since not all
AArch64 systems can run AArch32 and no ARM hardware can run AArch64.

FreeBSD does not have libdl, so set it via lit.cfg instead of the test
input, as with asan. Also remove it from Darwin test runs - it's not
necessary, but harmless there.
Add FreeBSD to the list of hosts to test.
