Justin Bogner 80bee97477 cmake: Don't try to install exports if there aren't any
When using LLVM_DISTRIBUTION_COMPONENTS, it's possible for LLVM's
export list to be empty. If this happens the install(EXPORTS) command
will fail, but since there isn't anything to install anyway we really
just want to skip it.

Mandeep Singh Grang 96999de55d [CMake] Fix llvm_setup_rpath function
Summary:
Set _install_rpath to CMAKE_INSTALL_RPATH if it is defined, so that eventually
INSTALL_RPATH is set to CMAKE_INSTALL_RPATH.
The "if(NOT DEFINED CMAKE_INSTALL_RPATH)" was missing a corresponding else
clause.
This also cleans up the fix made in r285908.

Michal Gorny bab7943c6c [cmake] Make LIT_COMMAND configurable and improve fallback support
Make LIT_COMMAND configurable, use source tree only when actually
available and extend the default search to other common executable names
'lit.py' and 'lit', in order to increase uniformity between all LLVM
projects and support using installed lit.

Changing the conditional used to determine whether in-tree or external
lit is being used covers the case when LLVM_MAIN_SRC_DIR is defined but
does not exist (anymore). In this case, the functions falls back to
looking for installed lit rather than attempting to use a non-existing
path. The same conditional is used in clang already.

Making LIT_COMMAND a cache variable in case the source tree variant is
used serves two purposes. Firstly, it increases uniformity between
the two branches since find_program() implicitly makes LIT_COMMAND
a cache variable. Secondly, it allows overriding the lit executable used
to run the tests when the LLVM source tree is provided. Gentoo is
planning to use this to use installed (and byte-compiled) lit instead of
re-compiling it in every LLVM project.

Extending default search is meant to increase uniformity between
different LLVM projects. The 'lit.py' name is already used by a few of
them, and 'lit' is the name used by utils/lit/setup.py when installing.

Michal Gorny 6b929d5ba9 [cmake] Reintroduce (ldconfig-compatible) SOVERSIONs on shared libraries
Reintroduce versioning of shared libraries via SOVERSION, addressing
the issues with the previous design, since Gentoo is relying
on shared-split install of LLVM. The SOVERSIONs were originally
introduced in r229720 for all libraries, and removed in r252093 in favor
of custom SONAME. As far as I understand, the major concern with the old
versioning was that the used versions were incompatible with ldconfig.

Having considered that, this commit introduce SOVERSIONS with the
following considerations:

1. SOVERSIONs are formed of major & minor version concatenated -- i.e.
for 4.0 its .so.40. This matches the common practice where the first
version number indicates ABI breakage, and therefore fixes the issues
with ldconfig. Additionally, VERSION with the remaining verion
components appended is used, however this is not strictly necessary.

2. The versioning is only applied to libraries with no explicit SONAME
specified -- i.e. it won't apply to libLLVM but only to the split
libraries. It will also apply to libraries installed by the subprojects.

3. The versioning is only done on *nix systems, Darwin excluded. This
matches the current use of SONAME.

Michal Gorny b002f6370b cmake: Install the OCaml libraries into a more correct path
Add a OCAML_INSTALL_PATH variable that can be used to control
the install path for OCaml libraries. The new variable defaults to
${OCAML_STDLIB_PATH}, i.e. the OCaml library path obtained from
the OCaml compiler. Install libraries into "llvm" subdirectory.

This fixes two issues:

1. OCaml library directories differ between systems, and 'lib/ocaml' is
incorrect e.g. on amd64 Gentoo where OCaml is installed
in 'lib64/ocaml'. Therefore, obtain the library path from the OCaml
compiler using 'ocamlc -where' (which is already used to set
OCAML_STDLIB_PATH), which is the method used commonly in OCaml packages.

2. The top-level directory is reserved for the standard library, and has
precedence over local directory in search path. As a result, OCaml
preferred the files installed along with previous LLVM version over the
source tree when building a new version, resulting in two versions being
mixed during the build. The new layout is used commonly by other OCaml
packages, and findlib is able to find the LLVM libraries successfully.

Michael Gottesman 31e9363a3e [cmake] Export gtest/gtest_main and its dependencies via a special build tree only cmake exports file.
Previously, gtest/gtest_main were not exported via cmake. The intention here was
to ensure that users whom are linking against the LLVM install tree would not
get the gtest/gtest_main targets. This prevents downstream projects that link
against the LLVM build tree (i.e. Swift) from getting this dependency
information in their cmake builds. Without such dependency information, linker
issues can result on linux due to LLVMSupport being put before gtest on the
linker command line.

This commit preserves behavior that we want for the install tree, while adding
support for the build tree by:

1. The special casing for gtest/gtest_main in the add_llvm_library code is
removed in favor of a flag called "BUILDTREE_ONLY". If this is set, then the
library is communicating that it is only meant to be exported into the build
tree and is not meant to be installed or exported via the install tree. This
part is just a tweak to remove the special case, the underlying code is the
same.

2. The cmake code that exports cmake targets for the build tree has special code
to import an additional targets file called
LLVMBuildTreeOnlyExports.cmake. Additionally the extra targets are added to the
LLVMConfig.cmake's LLVM_EXPORTED_TARGETS variable. In contrast, the
"installation" cmake file uses the normal LLVM_EXPORTS_TARGETS as before and
does not include the extra exports file. This is implemented by
defining/undefining variables when performing a configure of the build/install
tree LLVMConfig.cmake files.

Chris Bieneman 76864f9c77 [CMake] Cleanup LLVM_OPTIMIZED_TABLEGEN
This cleanup removes the need for the native support library to have its own target. That target was only needed because makefile builds were tripping over each other if two tablegen targets were building at the same time. This causes problems because the parallel make invocations through CMake can't communicate with each other. This is fixed by invoking make directly instead of through CMake which is how we handle this in External Project invocations.

The other part of the cleanup is to mark the custom commands as USES_TERMINAL. This is a bit of a hack, but we need to ensure that Ninja generators don't invoke multiple tablegen targets in the same build dir in parallel, because that too would be bad.

Marking as USES_TERMINAL does have some downside for Ninja because it results in decreased parallelism, but correct builds are worth the minor loss and LLVM_OPTIMZIED_TABLEGEN is such a huge win, it is worth it.

Rafael Espindola b940b66c60 Add an c++ itanium demangler to llvm.
This adds a copy of the demangler in libcxxabi.

The code also has no dependencies on anything else in LLVM. To enforce
that I added it as another library. That way a BUILD_SHARED_LIBS will
fail if anyone adds an use of StringRef for example.

The no llvm dependency combined with the fact that this has to build
on linux, OS X and Windows required a few changes to the code. In
particular:

    No constexpr.
    No alignas

On OS X at least this library has only one global symbol:
__ZN4llvm16itanium_demangleEPKcPcPmPi

My current plan is:

    Commit something like this
    Change lld to use it
    Change lldb to use it as the fallback

    Add a few #ifdefs so that exactly the same file can be used in
    libcxxabi to export abi::__cxa_demangle.

Once the fast demangler in lldb can handle any names this
implementation can be replaced with it and we will have the one true
demangler.

This renames:
LLVM_INCLUDE_DIRS -> LLVM_INCLUDE_DIR
LLVM_LIBRARY_DIRS -> LLVM_LIBRARY_DIR

The versions ending in S are not used in-tree anywhere. This also cleans up LLVM_LIBRARY_DIR being set to the same value with and without the "S".
