The Freescale SDK is based on OpenEmbedded, and this might be useful
for other OpenEmbedded-based configurations as well.
With minor modifications, patch by Tobias von Koch!

This change adds detection of C++ headers and libraries paths when
building with the standalone toolchain from Android NDK. They are in a
slightly unusual place.

Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".
Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

diagnostics for bad deployment targets and adding a few
more predicates. Includes a patch by Jonathan Schleifer
to enable ARC for ObjFW.

The hack of recognizing a -D__IPHONE_OS_VERSION_MIN_REQUIRED option
in place of -mios-simulator-version-min leaves the Darwin version
unspecified. It can be set separately with -mmacosx-version-min (which
makes no sense) or inferred to match the host version (which is unpredictable
and usually wrong). This really needs to get cleaned up, but in the
meantime, force the OS X version to 10.6 so that the behavior is sane for
the iOS simulator. Thanks for Argyrios for the patch.

target Objective-C runtime down to the frontend: break this
down into a single target runtime kind and version, and compute
all the relevant information from that. This makes it
relatively painless to add support for new runtimes to the
compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime. This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.
As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.
I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

option. On the driver, check if we are using libraries from gcc 4.7 or newer
and if so pass -fuse-init-array to the frontend.
The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in
.ctors, so we have to use .init_array.

architecture; this was happening for tools such as lipo and dsymutil.
Also, if no -arch option has been specified, set the architecture based
on the TC default.

inside of a sysroot targeting a system+sysroot which is "similar" or
"compatible" with the host system. This shows up when trying to build
system images on largely compatible hardware as-if fully cross compiled.
The problem is that previously we *perfectly* mimiced GCC here, and it
turns out GCC has a bug that no one has really stumbled across. GCC will
try to look in thy system prefix ('/usr/local' f.ex.) into which it is
instaled to find libraries installed along side GCC that should be
preferred to the base system libraries ('/usr' f.ex.). This seems not
unreasonable, but it has a very unfortunate consequence when combined
with a '--sysroot' which does *not* contain the GCC installation we're
using to complete the toolchain. That results in some of the host
system's library directories being searched during the link.
Now, it so happens that most folks doing stuff like this use
'--with-sysroot' and '--disable-multilib' when configuring GCC. Even
better, they're usually not cross-compiling to a target that is similar
to the host. As a result, searching the host for libraries doesn't
really matter -- most of the time weird directories get appended that
don't exist (no arm triple lib directory, etc). Even if you're
cross-compiling from 32-bit to 64-bit x86 or vice-versa, disabling
multilib makes it less likely that you'll actually find viable libraries
on the host. But that's just luck. We shouldn't rely on this, and this
patch disables looking in the system prefix containing the GCC
installation if that system prefix is *outside* of the sysroot. For
empty sysroots, this has no effect. Similarly, when using the GCC
*inside* of the sysroot, we still track wherever it is installed within
the sysroot and look there for libraries. But now we can use a cross
compiler GCC installation outside the system root, and only look for the
crtbegin.o in the GCC installation, and look for all the other libraries
inside the system root.
This should fix PR12478, allowing Clang to be used when building
a ChromiumOS image without polluting the image with libraries from the
host system.

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.
This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator. We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

NSNumber, and boolean literals. This includes both Sema and Codegen support.
Included is also support for new Objective-C container subscripting.
My apologies for the large patch. It was very difficult to break apart.
The patch introduces changes to the driver as well to cause clang to link
in additional runtime support when needed to support the new language features.
Docs are forthcoming to document the implementation and behavior of these features.

Debian multiarch libraries, this should in theory add support for those
platform's header search rules. I don't have a system to check this
with, so review appreciated. I've added the corresponding tests
referring to the debian multiarch tree.
We are starting to have a relatively completely tested Linux platform
for header search and library search, with several interesting
peculiarities. We should point people at the debian_multiarch_tree when
suggesting new tests. Folks with Debian systems that can check this for
correctness, it would be much appreciated. The missing chunks I know of
are testing bi-arch peudo-cross-compiling toolchains betwen 32-bit and
64-bit variants of platforms, and the MIPS and ARM Debian toolchains.

Patch from Michel Dänzer, sent our way via Jeremy Huddleston who added
64-bit support. I just added one other place where powerpc64-linux-gnu
was missing (we only had powerpc64-unknown-linux-gnu).
I've also added a tree to test out the debian multiarch stuff. I don't
use debian regularly, so I'm not certain this is entirely accurate. If
anyone wants to check it against a debian system and fix any
inaccuracies, fire away. This way at least folks can see how this is
*supposed* to be tested.
It'd be particularly good to get the Debian MIPS toolchains tested in
this way.

world on Solaris 11 for both x86 and x86-64 using the built-in assembler and
Solaris (not GNU) ld, however it currently relies on a hard-coded GCC location
to find crtbegin.o and crtend.o, as well as libgcc and libgcc_eh.

And remove HAVE_CLANG_CONFIG_H, now that the header is generated
in the autoconf build, too.
Reverts r149571/restores r149504, now that config.h is generated
correctly by LLVM's configure in all build configurations.
