Clang has better diagnostics in this case. It is not necessary therefore
to change the destructor to avoid what is effectively an invalid warning
in gcc. Instead, better handle the warning flags given to the compiler.

One of the earlier patches updated the cmake rule to install the

If you externalize debug info for unit tests the test runner finds the mach-o inside the dsym bundle and tries to execute it as a test.
llvm-svn: 255056
Summary: This adds support for generating dSYM files and stripping debug info from executables and dylibs. It also supports passing -object_path_lto to the linker to generate dSYMs for LTO builds.

CMAKE_EXE_LINKER_FLAGS is a string. Appending a flag using list(APPEND) introduces an extra
semicolon which breaks stuff. Change this to append the value in the same way that everyone else
seems to be doing.

Building clang with -fno-pie generates slightly faster code. In my not-very-rigorous testing I saw about a 4% speed up using the clang test-suite sources.

This is similar to the fix for FreeBSD in r226862. Without this patch,
the build aborts when linkling libLTO.so, complaining about undefined
references to assert2, cxa_atexit, etc.

On the average user's system, those libraries will not be compiled with
MSan. Prior to this change, the LLVM test suite was full of false
positives from calls from third party libraries to MSan interceptors
like strlen.
We can remove this check if MSan ever grows a suppression mechanism
similar to TSan's.

I'm unaware of any reasons why -fvisibility-inlines-hidden would depend on PIC, and since autoconf supports this flag without PIC, we should support it in CMake too.
llvm-svn: 253517
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.

Summary:
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.

r250835 unintentionally discarded the optional parameter to the
add_llvm_external_project() macro that may point to a path when the said
path is different from ${name}. This should fix it by passing ${ARGN} on
to add_llvm_subdirectory(). The problem manifests itself with e.g.
add_llvm_external_project(clang-tools-extra extra) from
clang/tools/CMakeLists.txt

This particularly helps enforce the C++ Rule of 5 (for new move ops this
is already an error, but for a type only using C++98 features (copy
ctor/assign, dtor) it is only deprecated, not invalid)
Applying the flag for any GCC compatible compiler - GCC doesn't warn on
the Rule of 5 cases that C++11 deprecates, but it doesn't have other
false positives so far as I could see (compiling with GCC 4.8 didn't
produce any -Wdeprecated warnings I could spot).

When building a plugin against an installed LLVM toolchain using
add_llvm_loadable_module (in the documented manner) doesn't work as nothing sets
the *_OUTPUT_INTDIR variables causing an error when set_output_directory is

to be used) fixes this.

Currently LLVM_COMPILER_IS_GCC_COMPATIBLE is set as a side-effect of determining
the stdlib to use in HandleLLVMStdlib, which causes problems when attempting to

from both AddLLVM and HandleLLVMStdlib.

In order to support building clang out-of-tree the install_symlink script needs to be installed, and it needs to be found by searching the CMAKE_MODULE_PATH.
This change renames install_symlink -> LLVMInstallSymlink so it doesn't conflict with naming from other projects, and adds searching behavior in AddLLVM.cmake
llvm-svn: 248009
Summary: This change generalizes symlink generation and makes symlinks to tools obey LLVM_TOOLCHAIN_TOOLS. It makes it so that if you exclude llvm-ar from LLVM_TOOLCHAIN_TOOLS you don't end up with broken symlinks to llvm-lib and llvm-ranlib in your install.

This amends chapuni's r246156 to handle an Xcode quirk, one even called out
in the CMake documentation:
Some native build systems may not like targets that have only object files,
so consider adding at least one real source file to any target that
references $<TARGET_OBJECTS:objlib>.
I've limited the scope of this hack to Xcode for now.
llvm-svn: 247305
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.
