Summary:
When using Xcode to build LLVM with code signing, the post-build rule is executed even if the actual build-step was skipped. This causes double-signing errors. We can currently only avoid it by passing the `--force` flag.
Plus some polishing for my previous patch D54443.

Allow clients to suppress setup of default RPATHs in designated library targets. This is used in LLDB when emitting liblldb as a framework bundle, which itself doesn't load further RPATH-dependent libraries.
This follows the approach in add_llvm_executable().

I found the pattern of setting the project_BUILD variable to OFF after
processing the project to be pretty confusing. Using global properties
to explicitly keep track of whether a project has been processed or not
seems much more straightforward, and it also allows us to convert the
macro into a function (which is required for the early return).
Factor the project+type+name combination out into a variable while I'm
here, since it's used a whole bunch of times.
I don't believe this should result in any functional changes.

Summary: When using `LLVM_EXTERNALIZE_DEBUGINFO` in LLDB, the default dSYM location for the shared library in LLDB.framework is inside the framework bundle. With `LLVM_EXTERNALIZE_DEBUGINFO_OUTPUT_DIR` we can easily fix that. I consider it a useful feature to be able to set a global output directory for external debug info (rather then having a target-specific one). Only implemented for Darwin so far.

When using multi-stage builds, we would like support cross-compilation.
Example is 2-stage build when the first stage is compiled for host while
the second stage is compiled for the target.
Normally, the second stage would be also used for compiling runtimes,
but that's not possible when cross-compiling, so we use the first stage
compiler instead. However, we still want to use the second stage paths.
To do so, we set the -resource-dir of the first stage compiler to point
to the resource directory of the second stage.
We also need compiler tools that support the target architecture. These
tools are not guaranteed to be present on the host, but in case of
multi-stage build, we can build these tools in the first stage.

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.
This is a re-land of r340435, with a few minor fix-ups. The issues causing the revert were addressed in r344218, r344219, and r344553.
llvm-svn: 344555
There really aren't any generator behaviors that we need to take `CMAKE_EXTRA_GENERATOR` into account for. Where we need to take different behaviors for IDEs is mostly in enabling or disabling certain build system features that are optional but trip up the IDE UIs. Like the generation of lots of utility targets.
By changing the LLVM_ENABLE_IDE default to only being on for multi-configuration generators, we allow gating where it will impact the UI presentation, while also supporting optionally disabling the generation if your tooling workflow encounters problems. Presently being able to manually disable extra target generation is useful for Visual Studio 2017's CMake integration where the IDE has trouble displaying and working with the large number of optional targets.
llvm-svn: 344553
All uses of this option have been removed, and the intent is to change the purpose and default value of this option. To prevent it from having impacts on users, this patch temporarily removes the option and purges it from CMake caches. In a few days, once this has propagated to contributors I will re-introduce the option with the new default value.
llvm-svn: 344219
Previously adding header and table gen files was conditional on using an IDE. Since these files have the `HEADER_FILE_ONLY` attribute applied they are ignored as sources by all non-IDE generators, so there is really no reason not to include them.
Additionally having the CMake always include these files allows the CMake-server to include them in the sources list for targets, which is valuable to anyone using CMake-server integrated tools.

Some projects rely on using libraries from the Windows SDK with their
original casing, just with a lowercase extension. E.g. the WinSock2 lib
is named WS2_32.Lib in the Windows SDK, and we would previously only
create a ws2_32.lib symlink for it (i.e. all lowercase). Also create a
WS2_32.lib symlink (i.e. original casing with lowercase extension) to
cover users of this casing. As a drive-by fix, only create these
symlinks when they differ from the original name to reduce the amount of
noise in the library symlinks directory.

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.

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.

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

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
in LLVMConfig.cmake. This fixes preserving the suffix set while building
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.

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.
