Summary:
This makes it so that IR files using triples without an environment work
out of the box, without normalizing them.
Typically, the MSVC behavior is more desirable. For example, it tends to
enable things like constant merging, use of associative comdats, etc.

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.

HermitCore is a POSIX-compatible kernel for running a single application in an isolated environment to get maximum performance and predictable runtime behavior. It can either be used bare-metal on hardware or a VM (Unikernel) or side by side to an existing Linux system (Multikernel).
Due to the latter feature, HermitCore binaries are marked with ELFOSABI_STANDALONE to let the Linux ELF loader distinguish them from regular Unix/Linux binaries and load them using the HermitCore "proxy" tool.

LLVM triple normalization is handling "unknown" and empty components
differently; for example given "x86_64-unknown-linux-gnu" and
"x86_64-linux-gnu" which should be equivalent, triple normalization
returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's
config.sub returns "x86_64-unknown-linux-gnu" for both
"x86_64-linux-gnu" and "x86_64-unknown-linux-gnu". This changes the
triple normalization to behave the same way, replacing empty triple
components with "unknown".

Summary: The lib paths are not correctly picked up for OpenEmbedded sysroots
(like arm-oe-linux-gnueabi). I fix this in a follow-up clang patch. But in
order to add the correct libs I need to detect if the vendor is oe. For this
reason, it is first necessary to teach llvm to detect oe vendor, which is what
this patch does.

Until this patch, only `powerpc` and `ppc32` were recognized as valid
PowerPC 32-bit architectures in a target triple. This was incompatible
with the triple `ppc-apple-darwin` as returned for libObject. I found
out about this when working on a test case using a binary generated on
an old PowerBook G4.
We had the choice of either fix this in the Mach-O object parser or
in the Triple implementation. I chose the latter because it feels like
the most canonical place.

Apple's iOS, tvOS and watchOS simulator platforms have never been clearly
distinguished in the target triples. Even though they are intended to
behave similarly to the corresponding device platforms, they have separate
SDKs and are really separate platforms from the compiler's perspective.
Clang now defines a macro when building for one of these simulator platforms
(r297866) but that relies on the very indirect mechanism of checking to see
which option was used to specify the minimum deployment target. That is not
so great. Swift would also like to distinguish these simulator platforms in
a similar way, but unlike Clang, Swift does not use a separate option to
specify the minimum deployment target -- it uses a -target option to
specify the target triple directly, including the OS version number.
Using a different target triple for the simulator platforms is a much
more direct and obvious way to specify this. Putting the "simulator" in
the environment component of the triple means the OS values can stay the
same and existing code the looks at the OS field will not be affected.

Summary:
This operating system type represents the AMDGPU PAL runtime, and will
be required by the AMDGPU backend in order to generate correct code for
this runtime.
Currently it generates the same code as not specifying an OS at all.
That will change in future commits.

This adds the OS check for the Haiku operating system, as it was

i586-pc-haiku were also added.
These patches only affect Haiku and are completely harmless for

Ananas is a home-brew operating system, mainly for amd64 machines. After

back - yet, having to manually patch things is annoying, so it'd be much

clang-format (https://reviews.llvm.org/D33932) to keep primary headers
at the top and handle new utility headers like 'gmock' consistently with
other utility headers.
No other change was made. I did no manual edits, all of this is
clang-format.
This should allow other changes to have more clear and focused diffs,
and is especially motivated by moving some headers into more focused
libraries.

Summary:
For AMDGPU, we have been using the operating system component of the triple
for specifying the low-level runtime that is being used. The rationale for
this is that the host operating system (e.g. Linux) is irrelevant for GPU code,
since its execution enviroment will be mostly controled by the low-level runtime
being used to execute the code.
In most cases, higher level languages have their own runtime which is
implemented on top of the low-level runtime. The kernel ABIs of each
language mostly depend on the low-level runtime, but there may be some
slight differences between languages. OpenCL for example, may append
additional arguments to the kernel in order to pass values like global
offsets or buffers for printf. OpenMP, HCC, or other languages may want
to add their own values which differ from OpenCL.
The reason for adding a new opencl environment type is to make it possible for the backend
to distinguish between the ABIs of the higher-level languages and handle them correctly.
It seems cleaner to use the enviroment component for this rather than creating a new
OS type for every combination of low-level runtime / high-level language.

The current approach isn't a long-term viable pattern. Given the set of
architectures A, vendors V, operating systems O, and environments E, it
does |A| * |V| * |O| * |E| * 4! tests. As LLVM grows, this test keeps
getting slower, despite my working very hard to make it get some
"optimizations" even in -O0 builds in order to lower the constant
factors. Fundamentally, we're doing an unreasonable amount of work.i
Looking at the specific thing being tested -- the goal seems very
clearly to be testing the *permutations*, not the *combinations*. The
combinations are driving up the complexity much more than anything else.
Instead, test every possible value for a given triple entry in every
permutation of *some* triple. This really seems to cover the core goal
of the test. Every single possible triple component is tested in every
position. But because we keep the rest of the triple constant, it does
so in a dramatically more scalable amount of time. With this model we do
(|A| + |V| + |O| + |E|) * 4! tests.
For me on a debug build, this goes from running for 19 seconds to 19
milliseconds, or a 1000x improvement. This makes a world of difference
for the critical path of 'ninja check-llvm' and other extremely common
workflows.
Thanks to Renato, Dean, and David for the helpful review comments and
helping me refine the explanation of the change.
