This fallback path is used at least on PPC.
If this doesn't work on some compilers that take this path,
then this will have to be changed to either abort,
or partitioned to do different things based on the compiler.
Please refer to https://reviews.llvm.org/D105338.
We've accumulated a scary amount of local patches to this directory. I
tried to merge them all, but if your favorite change is missing please
reapply it manually (and send it upstream).
Summary:
Simplifies the C++11-style "-> decltype(...)" return-type deduction.
Note that you have to be careful about whether the function return type
is `auto` or `decltype(auto)`. The difference is that bare `auto`
strips const and reference, just like lambda return type deduction. In
some cases that's what we want (or more likely, we know that the return
type is a value type), but whenever we're wrapping a templated function
which might return a reference, we need to be sure that the return type
is decltype(auto).
No functional change.

Clone+exec death test allocates a single page of stack to run chdir + exec on.
This is not enough when gtest is built with ASan and run on particular
hardware.
With ASan on x86_64, ExecDeathTestChildMain has frame size of 1728 bytes.
Call to chdir() in ExecDeathTestChildMain ends up in
_dl_runtime_resolve_xsavec, which attempts to save register state on the stack;
according to cpuid(0xd) XSAVE register save area size is 2568 on my machine.
This results in something like this in all death tests:
Result: died but not with expected error.

Renames GTEST_NO_LLVM_RAW_OSTREAM -> GTEST_NO_LLVM_SUPPORT and guards
the new features behind it.
This reverts commit a063bcf3ef5a879adbe9639a3c187d876eee0e66.
llvm-svn: 369527
Summary:
These are detected by gtest as containers, and so previously printed as e.g.
{ '.' (46, 0x2E), 's' (115, 0x73), 'e' (101, 0x65), 'c' (99, 0x63), '0' (48, 0x30) },
gtest itself overloads PrintTo for std::string and friends, we use the same mechanism.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
The operators simply print the underlying value or "None".
The trickier part of this patch is making sure the streaming operators
work even in unit tests (which was my primary motivation, though I can
also see them being useful elsewhere). Since the stream operator was a
template, implicit conversions did not kick in, and our gtest glue code
was explicitly introducing an implicit conversion to make sure other
implicit conversions do not kick in :P. I resolve that by specializing
llvm_gtest::StreamSwitch for llvm:Optional<T>.

Summary:
These are functions like operator<<(raw_ostream&, Foo).
Previously these were only supported for messages. In the assertion
EXPECT_EQ(A, B) << C;
the local modifications would explicitly try to use raw_ostream printing for C.
However A and B would look for a std::ostream printing function, and often fall
back to gtest's default "168 byte object <00 01 FE 42 ...>".
This patch pulls out the raw_ostream support into a new header under `custom/`.
I changed the mechanism: instead of a convertible stream, we wrap the printed
value in a proxy object to allow it to be sent to a std::ostream.
I think the new way is clearer.
I also changed the policy: we prefer raw_ostream printers over std::ostream
ones. This is because the fallback printers are defined using std::ostream,
while all the raw_ostream printers should be "good".

a cxxabi.h in the include search paths.
This comes up when libc++ is installed with some other abi library. At
some points in time in history we have had CMake hackery to try and get
a cxxabi.h installed that would work, but there are lots of examples
lacking this. Also, the just-built tree with libc++ seems to not quite
get this right.
To let folks make progress, we can easily work around this by detecting
that the header is missing and disabling the relevant parts of gtest.
This should fix the last remainging build bot failures. While these
failures are typically indicative of a questionable install, I don't
think gtest should be the thing that surfaces those issues and I don't
want folks blocked on this.

r100895 landed an llvm-only change to add minix support to googletest.
It did that by putting "defined()" in a macro, which has undefined
behavior. Slightly reshuffle things to remove that undefined behavior.
Also mention in README.LLVM that minix support is a local change.

Modern compilers (Clang 3.4, GCC 4.8) warn on variadic macros being
introduced in C99, which produces a huge number of useless diagnostics
since this macro is unused in the whole project.

This patch removes most of the trivial cases of weak vtables by pinning them to
a single object file. The memory leaks in this version have been fixed. Thanks

This change is incorrect. If you delete virtual destructor of both a base class
and a subclass, then the following code:
Base *foo = new Child();
delete foo;
will not cause the destructor for members of Child class. As a result, I observe
plently of memory leaks. Notable examples I investigated are:
ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl.

externally to simplify our integration of GoogleTest into LLVM. Also,
build the single source file gtest-all.cc instead of the individual
source files as we don't expect these to change and thus gain nothing
from increased incrementality in compiles.
This makes our standard build of googletest exactly like upstream's
recommended build and the sanitizer's build. It also simplifies the
steps of importing a new version should we ever want one.
