Sven van Haastregt 4e8337e001 [CMake] Avoid REVERSE on unset variable
If required_libs happens to remain unset, CMake would fail with:

  list sub-command REVERSE requires list to be present.

Fix by ensuring we do not attempt to reverse an unset variable.

Zachary Turner a0a738b184 Fix a configure issue with Visual Studio generators.
We can't put the unittest source dir map in the configuration
specific directory because VS doesn't have a configure-specific
directory, instead it only knows this at runtime.  So we have
to remove this from the path.  This in turn means that the path
will be slightly different in VS configurations vs non vs
configurations.  In the former, the source map will be in the
parent directory of the executable, and in the latter it will
be in the same directory as the executable.  So check both.

Zachary Turner e9f1df84af Add support for unittest inputs.
Occasionally it is useful to have unittest which take inputs.
While we normally try to have this test be more of a lit test
we occasionally don't have tools that can exercise the code
in the right way to test certain things.  LLDB has been using
this style of unit test for a while, particularly with regards
to how it tests core dump and minidump file parsing.  Recently
i needed this as well for the case where we want to test that
some of the PDB reading code works correctly.  It needs to
exercise the code in a way that is not covered by any dumper
and would be impractical to implement in one of the dumpers,
but requires a valid PDB file.  Since this is now needed by
more than one project, it makes sense to have this be a
generally supported thing that unit tests can do, and we just
encourage people to use this sparingly.

Kirill Bobyrev 0addd170ab Pull google/benchmark library to the LLVM tree
This patch pulls google/benchmark v1.4.1 into the LLVM tree so that any
project could use it for benchmark generation. A dummy benchmark is
added to `llvm/benchmarks/DummyYAML.cpp` to validate the correctness of
the build process.

The current version does not utilize LLVM LNT and LLVM CMake
infrastructure, but that might be sufficient for most users. Two
introduced CMake variables:

* `LLVM_INCLUDE_BENCHMARKS` (`ON` by default) generates benchmark
  targets
* `LLVM_BUILD_BENCHMARKS` (`OFF` by default) adds generated
  benchmark targets to the list of default LLVM targets (i.e. if `ON`
  benchmarks will be built upon standard build invocation, e.g. `ninja` or
  `make` with no specific targets)

List of modifications:

* `BENCHMARK_ENABLE_TESTING` is disabled
* `BENCHMARK_ENABLE_EXCEPTIONS` is disabled
* `BENCHMARK_ENABLE_INSTALL` is disabled
* `BENCHMARK_ENABLE_GTEST_TESTS` is disabled
* `BENCHMARK_DOWNLOAD_DEPENDENCIES` is disabled

Chris Bieneman dc622702aa [CMake] Use LLVM_ENABLE_IDE instead of CMAKE_CONFIGURATION_TYPES
There are several places where we use CMAKE_CONFIGURATION_TYPES to determine if we are using an IDE generator and in turn decide not to generate some of the convenience targets (like all the install-* and check-llvm-* targets). This decision is made because IDEs don't always deal well with the thousands of targets LLVM can generate.

This approach does not work for Visual Studio 15's new CMake integration. Because VS15 uses a Ninja generator, it isn't a multi-configuration build, and generating all these extra targets mucks up the UI and adds little value.

With this change we still don't generate these targets by default for Visual Studio and Xcode generators, and LLVM_ENABLE_IDE becomes a switch that can be enabled on the VS15 CMake builds, to improve the IDE experience.

Michal Gorny c4ede8f8af [cmake] Append LLVM_VERSION_SUFFIX to SOVERSION
Append LLVM_VERSION_SUFFIX to SOVERSION. This makes it possible
to use the suffix to differentiate binary-incompatible versions
of LLVM built via BUILD_SHARED_LIBS.

We are planning to use this to temporarily preserve ABI-incompatible
variants of LLVM while switching the system between them, e.g. when
rebuilding the system to use libc++. Normally this would mean that once
LLVM is rebuilt using libc++ all the reverse dependencies become
immediately broken. Using a distinct SOVERSION allows us to preserve
the ABI compatibility before all the packages are rebuilt.

Store LLVM_VERSION_SUFFIX along with other version components

LLVM to stand-alone builds of other components, e.g. clang,
and therefore improves uniformity between the two build models.

Given that there is no apparent reason to omit this part of version,
that it is distributed to subprojects when building as part of LLVM
and that it is included in LLVM_PACKAGE_VERSION, I think it was omitted
accidentally rather than done on purpose.

Philip Pfaffe 3b8b3c2a2c [CMake] Export the LLVM_LINK_LLVM_DYLIB setting
Summary:
When building out-of-tree tools, there are several macros available to
automate linking against llvm. An examples is `add_llvm_executable`, or
the clang variant of this.

These macros use the LLVM_LINK_LLVM_DYLIB option to decide whether to
link against libraries defined by setting LLVM_LINK_COMPONENTS or to
link against libLLVM instead. Currently this is problematic in
out-of-tree targets, because they cannot identify whether this option is
required or even available. If the option was enabled in LLVM's own
build, the clang libraries are built against libLLVM, so a client
linking against those must link against it too. On the other hand the
client can't just always link against it, because it might not be
available.

This is related to D44391, but that change assumed the client knew
whether they wanted the dylib or not.

since `ld64.lld -v` doesn't yield any useful version output, but we can
add that detection later, and in the meantime it's still useful to have
the ld64 identification.

just checking for the presence of an ld64 executable.

Petr Hosek 24b61ac832 [Support] Avoid normalization in sys::getDefaultTargetTriple
The return value of sys::getDefaultTargetTriple, which is derived from
-DLLVM_DEFAULT_TRIPLE, is used to construct tool names, default target,
and in the future also to control the search path directly; as such it
should be used textually, without interpretation by LLVM.

Normalization of this value may lead to unexpected results, for example
if we configure LLVM with -DLLVM_DEFAULT_TARGET_TRIPLE=x86_64-linux-gnu,
normalization will transform that value to x86_64--linux-gnu. Driver will
use that value to search for tools prefixed with x86_64--linux-gnu- which
may be confusing. This is also inconsistent with the behavior of the
--target flag which is taken as-is without any normalization and overrides
the value of LLVM_DEFAULT_TARGET_TRIPLE.

Users of sys::getDefaultTargetTriple already perform their own
normalization as needed, so this change shouldn't impact existing logic.

This change causes us to re-run tablegen for every single target on
every single build. This is much, much worse than the problem being
fixed AFAICT.

On my system, it makes a clean rebuild of `llc` with nothing changed go
from .5s to over 8s. On systems with less parallelism, slower file
systems, or high process startup overhead this will be even more
extreme.

The only way I see this could be a win is in clean builds where we churn
the filesystem. But I think incremental rebuild is more important, and
so if we want to re-instate this, it needs to be done in a way that
doesn't trigger constant re-runs of tablegen.

Summary:
Due to some android peculiarities, in some build configurations
(statically linked executables targeting older releases) we could detect
the presence of these functions (because they are present in libc.a,
where check_library_exists searches), but then fail to build because the
headers did not include the definition.

This attempts to remedy that by upgrading the check_library_exists to
check_symbol_exists, which will check that the function is declared too.

I am hoping that a more thorough check will make the messy #ifdef we
have accumulated in the code obsolete, so I optimistically try to remove
them.
