The problem with plugins on Windows is that when building a plugin DLL it needs
to explicitly link against something (an exe or DLL) if it uses symbols from
that thing, and that thing must explicitly export those symbols. Also there's a
limit of 65535 symbols that can be exported. This means that currently plugins
only work on Windows when using BUILD_SHARED_LIBS, and that doesn't work with
MSVC.
This patch adds an LLVM_EXPORT_SYMBOLS_FOR_PLUGINS option, which when enabled
automatically exports from all LLVM tools the symbols that a plugin could want
to use so that a plugin can link against a tool directly. Plugins can specify
what tool they link against by using PLUGIN_TOOL argument to llvm_add_library.
The option can also be enabled on Linux, though there all it should do is
restrict the set of symbols that are exported as by default all symbols are
exported.
This option is currently OFF by default, as while I've verified that it works
with MSVC, linux gcc, and cygwin gcc, I haven't tried mingw gcc and I have no
idea what will happen on OSX. Also unfortunately we can't turn on
LLVM_ENABLE_PLUGINS when the option is ON as bugpoint-passes needs to be
loaded by both bugpoint.exe and opt.exe which is incompatible with this
approach. Also currently clang plugins don't work with this approach, which
will be fixed in future patches.

Currently our cmake generates targets like check-llvm-unit and
check-llvm-transforms-loopunroll-x86, but not check-llvm-transforms or
check-llvm-transforms-adce. This is because the search for test suites
only lists the ones with a custom lit.cfg or lit.local.cfg.
Instead, we can do something a little smarter - any directory under
test that isn't called Inputs or inside a directory called Inputs is a
test suite.

Summary:
As per the discussion on LLVM-dev this patch proposes removing LLVM_ENABLE_TIMESTAMPS.
The only complicated bit of this patch is the Windows support. On windows we used to log an error if /INCREMENTAL was passed to the linker when timestamps were disabled.
With this change since timestamps in code are always disabled we will always compile on windows with /Brepro unless /INCREMENTAL is specified, and we will log a warning when /INCREMENTAL is specified to notify the user that the build will be non-deterministic.

Summary: For Incremental LTO, we need to make sure that an old
cache entry is not used when incrementally re-linking with a new
libLTO.
Adding a global LLVM_REVISION in llvm-config.h would for to
rebuild/relink the world for every "git pull"/"svn update".
So instead only libLTO is made dependent on the VCS and will
be rebuilt (and the dependent binaries relinked, i.e. as of
today: libLTO.dylib and llvm-lto).

1) We need to add this flag prior to adding any other, in case the user has
specified a -fmodule-cache-path= flag in their custom CXXFLAGS. Such a flag
causes -Werror builds to fail, and thus all config checks fail, until we add
the corresponding -fmodules flag. The modules selfhost bot does this, for
instance.
2) Delete module maps that were putting .cpp files into modules.
3) Enable -fmodules-local-submodule-visibility, to get proper module
visibility rules applied across submodules of the same module. Disable
-fmodules for C builds, since that flag is not available there.

This makes it so that when running 'ninja test-suite' from the top-level LLVM ninja build it *always* re-runs the ninja command in the test-suite directory.
This mechanism is required because the top-level ninja file doesn't have a view into the subdirectory dependency tree, so it can't know what, if anything, needs to be rebuilt.

Summary:
This is a re-commit of r257003, which was reverted,
along with the fixes from http://reviews.llvm.org/D15986.
r252532 added support for reporting the monolithic library
when LLVM_BUILD_LLVM_DYLIB is used. This would only be done
if the individual components were not found, and the dynamic
library is found.
This diff extends this as follows:
- If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared
library, even if all component libraries exist.
- Two flags, --link-shared and --link-static are introduced
to provide explicit guidance. If --link-shared is passed
and the shared library does not exist, an error results.
Additionally, changed the expected shared library names from
(e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an
installation (and then only in CMake builds I think?), and not
in the build tree; this breaks usage of llvm-config during
builds, e.g. by llvm-go.

add_version_info_from_vcs was setting SVN_REVISION to the last fetched

corresponding to HEAD. This leads to conflicts with the definition of

not the most recently fetched svn revision.

instead (as is done in GetSVN.cmake).

LLVM_ENABLE_TIMESTAMPS controls if timestamps are embedded into llvm's
binaries. Turning it off is useful for deterministic builds.
r246905 made it so that the define suddenly also controls if the binaries that
the llvm binaries _create_ embed timestamps or not – but this shouldn't be a
configure-time option. r256203/r256204 added a driver option to toggle this on
and off, so this patch now passes this driver option in LLVM_ENABLE_TIMESTAMPS
builds so that if LLVM_ENABLE_TIMESTAMPS is set, the build of LLVM is
deterministic – but the built clang can still write timestamps into other
executables when requested.
This also allows removing some of the test machinery added in r292012 to work
around this problem.

Summary:
This patch adds a new CMake module for working with ExternalProjects. This wrapper for ExternalProject supports using just-built tools and can hook up dependencies properly so that projects get cleared out.
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.

Summary:
Move handling of the SONAME option from add_llvm_library
to llvm_add_library, so that it can be used in sub-projects.
In particular, this makes it possible to have consistently
named shared libraries for LLVM, Clang and LLDB.
Also, base the SONAME and symlinks on the output name
by extracting the OUTPUT_NAME property, rather than assuming
it is the same as the target name.

This change makes the CMake build system generate libraries for Linux and Darwin matching the makefile build system.
Linux libraries follow the pattern lib${name}.${MAJOR}.${MINOR}.so so that ldconfig won't pick it up incorrectly.
Darwin libraries are not versioned.
Note: On linux the non-versioned symlink is generated at install-time not build time. I plan to fix that eventually, but I expect that is good enough for the purposes of fixing this bug.

Summary:
This prints NO if LLVM was built with -fno-rtti or an equivalent flag
and YES otherwise. The reasons to add -has-rtti rather than adding -fno-rtti
to --cxxflags are:
1. Building LLVM with -fno-rtti does not always mean that client
applications need this flag.
2. Some compilers have a different flag for disabling rtti, and the
compiler being used to build LLVM may not be the compiler being used to
build the application.

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.

Currently, if you call cmake with a typo in an LLVM_USE_SANITIZER
value, there's a cmake warning and the build goes on with no
sanitizers at all. This isn't a good behaviour, since cmake warnings
are fairly easy to miss and the resulting behaviour is that it looks
like the build is sanitizer clean.
Upgrade these warnings to errors so misconfigurations are more
obvious.

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.

gtest and gtest_main) when generating ``Makefile.llvmbuild``.
Libraries that are not installed should not be exported because they
won't be available from an install tree. Rather than filtering out the
gtest libraries in cmake/modules/Makefile, simply teach llvm-build to
filter out libraries that will not be installed from its generated list
of exported libraries.
Note that LLVMBUILD_LIB_DEPS_* are used during our own CMake build
process so we cannot filter LLVMBUILD_LIB_DEPS_gtest* out in llvm-build.
We must leave this gtest filter logic in cmake/modules/Makefile.

Move `LLVM_LIBS_TO_EXPORT` over to Makefile.llvmbuild and generate it
from `llvm-build` using the same logic used to export the dependencies
of these libraries. This avoids depending on `llvm-config`.
This refactoring was originally motivated by issue #24154 due to commit
r243297 (Fix `llvm-config` to emit the linker flag for the combined
shared object, 2015-07-27) changing the output of `llvm-config --libs`
to not have the individual libraries when we configure with
`--enable-shared`. That change was reverted by r244108 but this
refactoring makes sense on its own anyway.

Predefining _DEBUG_POINTER_IMPL disables Visual C++ 2013 headers from defining
it to a function performing the null pointer check. In practice, it's not that
bad since any function actually using the nullptr will seg fault. The other
iterator sanity checks remain enabled in the headers.

This patch never puts LLVM_EXTERNAL_${nameUPPER}_SOURCE_DIR into the cache. It will only end up in the cache if it is specified on the command line, which is the correct behavior.
There is also a temporary change to remove non-default values from the cache if they are already present.

Summary:
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:
* factored out canonicalizing tool names from paths to CMake variables
* removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

This patch changes linkage with dbghlp.dll for clang from static (at load time)
to on demand (at the first use of required functions). Clang uses dbghlp.dll
only in minor use-cases. First of all in case of crash and in case of plugin load.
The dbghlp.dll library can be absent on system. In this case clang will fail
to load. With lazy load of dbghlp.dll clang can work even if dbghlp.dll
is not available.

generated by the Autoconf/Makefile build system relocatable.
Previously the generated CMake files contained hardcoded paths which
prevented a binary installation from being relocated to a different
place in the file system. This problem was most noticeable in LLVM's
official binary releases which were completely unusable by a downstream
project trying to import the CMake targets.
Package maintainers who choose to modify the install location of the
CMake directory without using the ``PROJ_cmake`` Makefile variable
override will need to patch the generated``LLVMConfig.cmake`` so that
``LLVM_INSTALL_PREFIX`` and ``_LLVM_CMAKE_DIR`` variables are set
correctly.

CMake files and should not be by both build systems and also the targets
were also installed by the CMake build system which they should not be.
The problem was that
- the CMake build of LLVM installs and exports the gtest library
targets. We should not being doing this, these are not part of LLVM.
- the Autoconf/Makefile build of LLVM still had gtest libraries in the
installed LLVMConfig.cmake.
These problems would cause problems for an external project because when
calling llvm_map_components_to_libnames(XXX all) ${XXX} would to contain
LLVM's internal gtest libraries.

ctypes 0.3 and earlier contains an interface-definig bug:
its ptr_of_raw_address accepts Int64 and not Nativeint. ctypes 0.4
was not released during the 3.6 cycle, and because of that, LLVM 3.6
was released with ctypes 0.3 as a dependency, which now breaks
the build on modern ctypes.
Unbreak.

The cmake check for whether libatomic could be used had been
unconditionally setting the result to false. Which was somewhat
fortunate, because the prerequisite check for whether it was *needed*
was always claiming it was, even if it was not.
However, this made platforms where libatomic is actually necessary
fail to link.

I can't actually test this properly because uninstalling MSVC 2015 CTP 6
and reinstalling the 2015 RC takes hours. I can only verify that this
doesn't mess up MSVC 2013 and 2015 CTP 6 builds, which is what I've
done.

In CMake dependencies can be filenames or targets, and targets can't be filenames. The Ninja generator handles filename dependencies because it generates targets for every output file from a command. For example:
add_custom_command(OUTPUT foo.txt COMMAND touch foo.txt)
With the Ninja generator this generates a target foo.txt, but with the Makefile generator it doesn't. This is probably because Ninja explicitly requires these hard dependency ties, and Make just behaves oddly in general.
To fix this we need to make the tablegen actions depend on a target rather than a filename.

This adds the following targets to cmake. These can be used to build and link only specific parts of a backend, instead of having to link the whole backend.
- AllTargetsAsmPrinters, AllTargetsAsmParsers, AllTargetsDescs, AllTargetsDisassemblers, AllTargetsInfos
A typical use for these is instead of linking ${LLVM_TARGETS_TO_BUILD}. This commit changes llvm-mc to show how to use the new targets.

The CMake install command is defined as:
install(TARGETS targets... [EXPORT <export-name>]
[[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
[DESTINATION <dir>]
[INCLUDES DESTINATION [<dir> ...]]
[PERMISSIONS permissions...]
[CONFIGURATIONS [Debug|Release|...]]
[COMPONENT <component>]
[OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
] [...])
This means it can only take one parameter from the set of RUNTIME, LIBRARY, or ARCHIVE. If you set more than one of these it seems to gobble up the extra arguments and ignore the COMPONENT argument.
This adds a check to only set LIBRARY or ARCHIVE based on whether or not the library being built is shared.

Certain versions of CMake specify /W3 as part of CMAKE_CXX_FLAGS
by default, before you do anything. Appending /W4 to the end of
this and using the Ninja generator results in
cl : Command line warning D9025 : overriding '/W3' with '/W4'.
It is not possible to suppress this since it is a command line
warning and not a compiler warning, so we must fix the command
line to contain only one value for /Wn.

Unfortunately, on ELF there is not used attribute on the .o files,
so there is no easy way to keep the dump function alive.
If we are not gcing, we may as well produce non gcable files and
avoid the cost.
Linking a debug clang now takes 18.856225992 seconds, before it
