[CMake] Connect Compiler-RT targets to LLVM Runtimes directory This patch builds on LLVM r279776. In this patch I've done some cleanup and abstracted three common steps runtime components have in their CMakeLists files, and added a fourth. The three steps I abstract are: (1) Add a top-level target (i.e asan, msan, ...) (2) Set the target properties for sorting files in IDE generators (3) Make the compiler-rt target depend on the top-level target The new step is to check if a command named "runtime_register_component" is defined, and to call it with the component name. The runtime_register_component command is defined in llvm/runtimes/CMakeLists.txt, and presently just adds the component to a list of sub-components, which later gets used to generate target mappings. With this patch a new workflow for runtimes builds is supported. The new workflow when building runtimes from the LLVM runtimes directory is: > cmake [...] > ninja runtimes-configure > ninja asan The "runtimes-configure" target builds all the dependencies for configuring the runtimes projects, and runs CMake on the runtimes projects. Running the runtimes CMake generates a list of targets to bind into the top-level CMake so subsequent build invocations will have access to some of Compiler-RT's targets through the top-level build. Note: This patch does exclude some top-level targets from compiler-rt libraries because they either don't install files (sanitizer_common), or don't have a cooresponding `check` target (stats). llvm-svn: 279863

add_compiler_rt_component(cfi)
Cross-DSO control flow integrity (compiler-rt part). This is an initial version of the runtime cross-DSO CFI support library. It contains a number of FIXMEs, ex. it does not support the diagnostic mode nor dlopen/dlclose, but it works and can be tested. Diagnostic mode, in particular, would require some refactoring (we'd like to gather all CFI hooks in the UBSan library into one function so that we could easier pass the diagnostic information down to __cfi_check). It will be implemented later. Once the diagnostic mode is in, I plan to create a second test configuration to run all existing tests in both modes. For now, this patch includes only a few new cross-DSO tests. llvm-svn: 255695

Make the cfi target available on more platforms. On non-Linux targets it just installs the blacklist. Differential Revision: https://reviews.llvm.org/D38661 llvm-svn: 315215
