2016-06-02[libcxxabi] Allow target flags to affect configuration tests.Eric Fiselier
Summary: This patch changes the libc++abi CMake so that it adds certain target flags like '-m32' or '--gcc-toolchain' before including `config-ix.cmake`. Since these flags can affect things like `check_library_exists([...])` they needed to be added before the tests are performed. Additionally this patch adds `LIBCXXABI_BUILD_32_BITS` which defaults to `LLVM_BUILD_32_BITS`.

2016-05-31[libcxxabi] Introduce a -fno-exceptions libc++abi libary variantAsiri Rathnayake
Currently there is only support for a -fno-exceptions libc++ build. This is problematic for functions such as std::terminate() which are defined in libc++abi and using any of those functions throws away most of the benefits of using -fno-exceptions (code-size). This patch introduces a -fno-exceptions libc++abi build to address this issue. This new variant of libc++abi cannot be linked against any with-exceptions code as some symbols necessary for handling exceptions are missing in this library.

Enable building libc++abi with hidden visibility by default. The ABI mandated interfaces (and a few extra) are already set up to be externally visible.

2016-05-25Allow explicit pthread opt-inBen Craig
When building libcxxabi in tree (i.e. in llvm/projects/libcxxabi, along with llvm/projects/libcxx), libcxx's config_site.in doesn't get created in a timely manner. This means that any configuration that is normally set in libcxx's config_site.in needs to be duplicated in libcxxabi to successfully build libcxxabi. This patch does exactly that for the _LIBCPP_HAS_THREAD_API_PTHREAD preprocessor define. http://reviews.llvm.org/D20574 git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@270732 91177308-0d34-0410-b5e6-96231b3b80d8

2016-04-18Respect LIBCXXABI_LIBDIR_SUFFIX before an installBen Craig
Prior to this patch, setting LIBCXXABI_LIBDIR_SUFFIX would confuse the check-libcxxabi target. libc++abi.* would get output to lib instead of lib${LIBCXXABI_LIBDIR_SUFFIX}, but the tests would look in the suffixed directory. Now, we match what libcxx does, and set the CMAKE_*_OUTPUT_DIRECTORY to the LIBRARY_DIR. http://reviews.llvm.org/D17410 git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@266611 91177308-0d34-0410-b5e6-96231b3b80d8

2015-03-03[libcxxabi] Build both static and shared versions of libc++abi by default.Eric Fiselier
Summary: This patch builds both static and shared versions of libc++abi by default. It adds/repurposes the following cmake options: * `LIBCXXABI_ENABLE_SHARED`: Enable/disable building the shared library. (Previously using `OFF` would build the static library instead) * `LIBCXXABI_ENABLE_STATIC`: Enable/disable building the static library. This patch also re-purposes the CMake target `cxxabi` to be a meta-target for `cxxabi_shared` and `cxxabi_static`. This could potentially break other builds that depend on `cxxabi` being a library target. We will need to apply a patch to libc++'s CMake before committing this change. Running the tests is still only supported when the shared version is built. Support for running the tests against the static library will come in another patch.

misc cleanup). Summary: The main section of this patch teaches CMake a new option `LIBCXXABI_LIBCXX_PATH` that specifies the path to the libcxx source root. This information is passed to lit so that it can better find libc++'s python module. `LIBCXXABI_LIBCXX_PATH` is also used to help find the libc++ headers. The rest of this patch is misc cleanup, mostly to make pep8 and pylint happy. I've also copied libc++'s .gitignore into libc++abi.

2014-12-29[cmake/multilib] Teach libc++abi's CMake build to support multilibChandler Carruth
libdir suffixes like 'lib64' or 'lib32'. This support is currently very rhudimentary. We define a variable LIBCXXABI_LIBDIR_SUFFIX. In a standalone build of libc++abi this can be directly set as a cached variable to control the multilib suffix used. When building libc++abi within a larger LLVM build, it is hard wired to whatever LLVM libdir suffix has been selected. If this doesn't work for someone, just let me know. I'm happy to change it. Unfortunately, libc++abi's lit setup made this somewhat problematic to change. It was setting variables up in a way that caused the resulting build to not work with lit at all. To fix that, I've moved some variables around in the CMake build to more closely match where and how they are defined in the libc++ CMake build. This includes specifically defining a library root variable in the CMake build where the libdir suffix can be applied, and then using that rather than re-computing it from the object directory in the lit config. This is essentially new functionality for libc++abi so I don't expect it to have any impact for folks until they start setting these variables. However, I know libc++abi is built in a diverse set of environments so just let me know if this causes you any problems. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@224927 91177308-0d34-0410-b5e6-96231b3b80d8
