2018-10-08[CMake] Link to compiler-rt if LIBUNWIND_USE_COMPILER_RT is ON.Charles Davis
Summary: If `-nodefaultlibs` is given, we weren't actually linking to it. This was true irrespective of passing `-rtlib=compiler-rt` (see previous patch). Now we explicitly link it to handle that case. I wonder if we should be linking these libraries only if we're using `-nodefaultlibs`...

Even though SEH for ARM is incomplete, make what code already exists at least compile correctly. The _LIBUNWIND_CURSOR_SIZE wasn't correct. ARM (and AArch64) have a DISPATCHER_CONTEXT field named TargetPc instead of TargetIp. For the libunwind.h UNW_* constants, there is no UNW_ARM_PC, only UNW_ARM_IP.

Special thanks to KJK::Hyperion for his excellent series of articles on how EH works on x86-64 Windows. (Seriously, check it out. It's awesome.) I'm actually not sure if this should go in as is.

This is essential when building with -nodefaultlibs. In some CMake versions (noticed in 3.5.1), the same libraries are picked up from CMAKE_REQUIRED_LIBRARIES in some exceptional situations (if CXX probing failed, due to libc++ not being built yet, the libraries from CMAKE_REQUIRED_LIBRARIES are used for linking the target library), but not at all in other newer CMake versions (3.10).

Currently it's only possible to control whether shared or static library build of libc++, libc++abi and libunwind is enabled or disabled and whether to install everything we've built or not. However, it'd be useful to have more fine grained control, e.g. when static libraries are merged together into libc++.a we don't need to install libc++abi.a and libunwind.a.

2018-06-28Support for multiarch runtimes layoutPetr Hosek
This change adds a support for multiarch style runtimes layout, so in addition to the existing layout where runtimes get installed to: lib/clang/$version/lib/$os Clang now allows runtimes to be installed to: lib/clang/$version/$target/lib This also includes libc++, libc++abi and libunwind; today those are assumed to be in Clang library directory built for host, with the new layout it is possible to install libc++, libc++abi and libunwind into the runtime directory built for different targets. The use of new layout is enabled by setting the LLVM_ENABLE_RUNTIME_TARGET_DIR CMake variable and is supported by both projects and runtimes layouts. The runtimes CMake build has been further modified to use the new layout when building runtimes for multiple targets.
