2017-11-17[libcxxabi][CMake] Provide option to disable installing of the libraryPetr Hosek
This is useful in cases where we only build static library and libc++abi.a is combined with libc++.a into a single archive in which case we don't want to have libc++abi.a installed separately. The same option is already provided by libcxx CMake build.

2017-05-10[libc++abi] Disable libc++ extern templates project-wideShoaib Meenai
libc++abi can't depend on libc++, so disable extern templates in libc++ headers project-wide. This was previously done in cxa_demangle.cpp, but I consider it more appropriate to do at the cmake level (since none of libc++abi's source files can use libc++ extern templates). I also think the _LIBCPP_NO_EXCEPTIONS in cxa_demangle.cpp is suspicious, but I'm doing one thing at a time.

2017-04-04Fix exception address alignment test for EHABIAsiri Rathnayake
This test fails on ARM bare-metal targets because it assumes the Itanium ABI, whereas EHABI requires the exception address to be 8-byte aligned. I was a bit puzzled at first because this should've failed on the public arm-linux builder too. I think the reason it passes there is because we don't include libunwind headers in the include path when running the libcxxabi tests, so the system unwind.h gets picked up.

Summary: Currently both libc++ and libc++abi provide definitions for operator new/delete. However I believe this is incorrect and that one or the other should offer them. This patch adds the CMake option `-DLIBCXXABI_ENABLE_NEW_DELETE_DEFINITIONS` which defaults to `OFF` unless otherwise specified.

2016-11-13[CMake] Fix libc++abi arm build w/o libunwind.Logan Chien
This commit fixes libc++abi build when LLVM unwinder (libunwind_llvm) is not enabled. This commit fixes the problem by removing "LLVM_NATIVE_ARCH MATCHES ARM" from CMakeLists.txt so that LIBCXXABI_USE_LLVM_UNWINDER will only be defined when LLVM unwinder is enabled. We need LIBCXXABI_USE_LLVM_UNWINDER becase there is a subtle difference between the unwinder from libgcc and the one from libunwind_llvm. For the unwinder from libgcc, we have to initialize register r12 with the address of _Unwind_Control_Block; otherwise, _Unwind_GetLanguageSpecificData() and _Unwind_GetRegionStart() won't work properly. Consequently, there is an extra _Unwind_SetGR() when LLVM unwinder is disabled.
