Support overriding the Doxygen & OCamldoc install directories,
and provide a more FHS-compliant defaults for both of them. This extends
r282240 that added this override for Sphinx-built documentation.
LLVM_INSTALL_DOXYGEN_HTML_DIR and LLVM_INSTALL_OCAMLDOC_HTML_DIR are
added, to control the location where Doxygen-generated and
OCamldoc-generated HTML docs are installed appropriately. They both
specify CMake-style install paths, and therefore can either by relative
to the install prefix or absolute.
The new defaults are subdirectories of share/doc/llvm, and replace
the previous directories of 'docs/html' and 'docs/ocaml/html' that
resulted in creating invalid '/usr/docs' that furthermore lacked proper
namespacing for the LLVM package. The new defaults are consistent with
the ones used for Sphinx HTML documentation, differing only in the last
component. Since the 'html' subdirectory is already used for Sphinx
docs, the 'doxygen-html' and 'ocaml-html' directories are used instead.

My previous attempt at this connected the sub-project check targets to the test-depends target instead of to the check-all target. That resulted in the tests running multiple times on bots that built "test-depends" and "check-all" in separate build invocations.

The Xcode and Visual Studio generators always log "-- No build type selected, default to Debug". This is because CMake doesn't initialize "CMAKE_CONFIGURATION_TYPES" until the generator's EnableLanguage call gets hit.
The first place EnableLanguage gets hit in our configuration is in the project() call. Since CMAKE_BUILD_TYPE isn't used until after we call project() it is safe to just move this check down a bit.

This patch has the following changes
The CMake variable LLVM_CCACHE_BUILD is set to OFF by default.
Set this to ON for a ccache enabled build
CCACHE_CPP2 is required to compile the source file directly instead
of compiling the preprocessed file. This will help WERROR is turned ON
for a host clang compiler
The below two options makes more sense in the context of a buildbot
CCACHE_HASHDIR is required to maintain the separate cached data across
builders. This will also help the debuggers to point to the correct source
location
CCACHE_SIZE is important in the perspective of buildbot to increase the
limit on the amount of data to hold in cache for faster compilation
CCACHE_DIR is used to save the cached data to a specific directory.

OS X 10.11 has a feature named System Integrity Protection. The goal of the feature is to make system binaries immutable (even as root). One part of this is that protected binaries do not receive DYLD_* environment variables because the kernel scrubs them before process launch.
This causes problems for LTO bootstrap builds on Darwin that try to use the just-built libLTO with the host ar, ranlib, or libtool.
This patch addresses two problems.
(1) The tools themselves aren't protected binaries but the shim tools installed at / are, so we need to call xcrun -find to find libtool instead of using the one CMake finds.
(2) Some build tools (ninja and make) use /bin/sh to invoke their subprocesses. Since /bin/sh is a system binary, the kernel scrubs the DYLD envars from their environment. To work around this we need to set the environment variables as part of the archiver commands, so the envars are set by the shell process instead of on the shell process.
llvm-svn: 276710
It's been pointed out that arbitrarily spraying raw profiles into a
build directory is insane. Doing this wastes a tremendous amount of
space and is also very lossy, since the test harness tends to wipe away
temporary sub-directories (which usually contain relevant profile data).
The new default is a `profiles` directory inside of the build dir.
llvm-svn: 276504
This does not change anything by default since LLVM_INCLUDE_UTILS is already set
to TRUE by default. In addition, since LLVM_INCLUDE_TESTS => LLVM_INCLUDE_UTILS,
the only way that this can cause changes is in the case where LLVM_INCLUDE_UTILS
is set to TRUE, but LLVM_INCLUDE_TESTS is FALSE. In that case, building gtest is
not a huge cost.
The reason to do this is that without this change, one can not turn off
LLVM_INCLUDE_TESTS in downstream projects that also use gtest for unittests. It
also just in general makes more sense since LLVM_INCLUDE_UTILS gates FileCheck
and other utilities that are along the lines of gtest.
Additionally from talking with chandlerc, this was not done for any specific
reason, so there is no reason not to do it and lots of benefit to doing it.

This option is the equivalent option to LLVM_BUILD_TOOLS but for executables
created via add_llvm_utility.
This is a useful tool for improving compile time in situations where LLVM is
used as a library and no testing tools are needed.
It follows the exact same implemention model as LLVM_BUILD_TOOLS.
Since the option is by default set to on, no behavior is changed unless one sets
it from the command line to be false.

When compiling with modules, header A and B can be in the same module M.
B depends on intrinsics_gen and A doesn't. Compiling a source file #include-ing
header A, we implicitly request module M to be built. It puts header A and B in
the same TU and tries to build them. Since B depends on intrinsics_gen (which
might not be built yet) we run into build failures.
This should fix our modules buildbot.

On Darwin it is currently impossible to build LLVM with modules

Summary:
There are a few LLVM projects that produce runtime libraries. Ideally
runtime libraries should be built differently than other projects,
specifically they should be built using the just-built toolchain.
There is support for building compiler-rt in this way from the clang
build. Moving this logic into the LLVM build is interesting because it
provides a simpler way to extend the just-built toolchain to include
LLD and the LLVM object file tools.
Once this functionality is better fleshed out and tested we’ll want to
encapsulate it in a module that can be used for clang standalone
builds, and we’ll want to make it the default way to build compiler-rt.
With this patch applied there is no immediate change in the build.
Moving compiler-rt out from llvm/projects into llvm/runtimes enables
the functionality.
This code has a few improvements over the method provided by
LLVM_BUILD_EXTERNAL_COMPILER_RT. Specifically the sub-ninja command is
always invoked, so changes to compiler-rt source files will get built
properly, so this patch can be used for iterative development with
just-built tools.
This first patch only works with compiler-rt. Support for other
runtime projects will be coming in follow-up patches.

Summary:
Before this change certain Polly variables have been used both as user-facing
CACHED cmake variables as well as uncached internal variables. Even though
this seems to have worked OK in practice, the behavior only worked due to
one variable shadowing the other. This behavior has been found confusing.
To make the use of cmake variables more clear we now prefix the cached, user
facing variables with LLVM_ as it is common habit for LLVM options and also
moved the _POLLY_ term to the beginning to ensure related options are sorted
after each other. The variables that control the behavior of LLVM/Polly are then
set by forwarding the values set in the user facing option variables.
As a result, Polly is now enabled with LLVM_POLLY_BUILD instead of BUILD_POLLY
and the linking behavior of Polly is controlled with LLVM_POLLY_LINK_INTO_TOOLS
instead of LINK_POLLY_INTO_TOOLS.

This is the second try. This time we disable this feature if no Polly checkout

early enough that our decision is known before cmake generates Config/config.h.
With Polly checked into LLVM it was since a long time possible to compile
clang/opt/bugpoint with Polly support directly linked in, instead of only
providing Polly as a separate loadable module. This commit switches the
default from providing Polly as a module to linking Polly into tools, such
that it becomes unnecessary to load the Polly module when playing with Polly.
Such configuration has shown a lot more convenient for day-to-day Polly use.
This change does not impact the default behavior of any tool, if Polly is not

If anybody is actually using this, it probably doesn't do what they

The idea here is to provide a customizable install target that only depends on building the things you actually want to install. It relies on each component being installed having an auto-generated install-${component}, which in turn depends only on the target being installed.
This is fundamentally a workaround for the fact that CMake generates build files which have their "install" target depend on the "all" target. This results in "ninja install" building a bunch of unneeded things.

The example usage here is for the llvm test-suite. In this example, the test-suite is setup as dependent on clang and lld if they are in-tree. If the clang or lld binaries change the test-suite is re-configured, cleaned, and rebuilt.
This cleanup and abstraction wrapping ExternalProject can be extended and applied to other runtime libraries like compiler-rt and libcxx.

CMake 3.0 introduced the VERSION option for the project() command. If you don't specify the VERSION in the function it will clear out variables matching ${PROJECT_NAME}_VERSION_${MAJOR|MINOR|PATCH|TWEAK}.
This makes overriding LLVM_VERSION_* not work properly with newer versions of CMake. To make this work properly we need to:
(1) Optionally set the policy to NEW
(2) Move default versions and setting PACKAGE_VERSION to before the call to project()
(3) If the policy is set, pass the VERSION and LANGUAGES options in the new format
This change should have no behavioral change for CMake versions before 3.0, and it makes the behavior of later versions match the earlier versions.

Summary:
Cross-compilation uses recursive cmake invocations to build native host
tools. These recursive invocations only forward a fixed set of
variables/options, since the native environment is generally the default.
This change adds -DLLVM_TARGET_IS_CROSSCOMPILE_HOST=TRUE to the recursive
cmake invocations, so that cmake files can distinguish these recursive
invocations from top-level ones, which can explain why expected options
are unset.
LLILC will use this to avoid trying to generate its build rules in the
crosscompile native host target (where it is not needed), which would fail
if attempted because LLILC requires a cmake variable passed on the command
line, which is not forwarded in the recursive invocation.

Summary:
This diff attempts to address the concerns raised in
http://reviews.llvm.org/D12488.
We introduce a new USE_SHARED option to llvm_config,
which, if set, causes the target to be linked against
libLLVM.
add_llvm_utility now uniformly disables linking against
libLLVM. These utilities are not intended for distribution,
and this keeps the option handling more centralised.
llvm-shlib is now processes before any other "tools"
subdirectories, ensuring the libLLVM target is defined
before its dependents.
One main difference from what was requested: llvm_config
does not prune LLVM_DYLIB_COMPONENTS from the components
passed into explicit_llvm_config. This is because the "all"
component does something special, adding additional
libraries (namely libLTO). Adding the component libraries
after libLLVM should not be a problem, as symbols will be
resolved in libLLVM first.
Finally, I'm not really happy with the
DISABLE_LLVM_LINK_LLVM option, but I'm not sure of a
better way to get the following:
- link all tools and shared libraries to libLLVM if
LLVM_LINK_LLVM_DYLIB is set
- some way of explicitly *not* doing so for utilities
and libLLVM itself
Suggestions for improvement here are particularly welcome.

Summary:
Three closely related changes, to have a mode in which we link all
executables and shared libraries against libLLVM.
1. Add a new LLVM_LINK_LLVM_DYLIB cmake option, which, when ON, will link
executables and shared libraries against libLLVM. For this to work, it
is necessary to also set LLVM_BUILD_LLVM_DYLIB and LLVM_DYLIB_EXPORT_ALL.
It is not strictly necessary to set LLVM_DISABLE_LLVM_DYLIB_ATEXIT, but
we also default to OFF in this mode, or tools tend to misbehave (e.g.
stdout may not flush on exit when output is buffered.)
llvm-config and Tablegen do not use libLLVM, as they are dependencies of
libLLVM.
2. Modify llvm-go to take a new flag, "linkmode=component-libs|dylib".
Depending on which one is passed (default is component-libs), we link
with the individual libraries or libLLVM respectively. We pass in dylib
when LLVM_LINK_LLVM_DYLIB is ON.
3. Fix LLVM_DYLIB_EXPORT_ALL on Linux, and expand the symbols exported to
actually export all. Don't strip leading underscore from symbols on Linux,
and make sure we get all exported symbols and weak-with-default symbols
("W" in nm output). Without these changes, passes won't load because
the "Annotate..." symbols defined in lib/Support/Valigrind.cpp are not
found.
Testing:
- Ran default build ("ninja") with LLVM, clang, compiler-rt, llgo, lldb.
- Ran "check", "check-clang", "check-tsan", "check-libgo" targets. I've
never had much success with LLDB tests, and llgoi is currently broken
so check-llgo fails for an unrelated reason.
- Ran "lldb" to ensure it loads.

Fail-fast iterators that have been invalidated due to insertion into
the host `DenseMap` deterministically trip an assert (in debug mode)

issues.
Enabling fail-fast iterators breaks the LLVM C++ ABI, so they are

`LLVM_ENABLE_ABI_BREAKING_CHECKS` by default flips with
`LLVM_ENABLE_ASSERTS`, but can be clamped to ON or OFF using the CMake /

CMake 3.2 changed the Ninja generator to list both the .exe and .lib
