[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(safestack)
Protection against stack-based memory corruption errors using SafeStack: compiler-rt runtime support library This patch adds runtime support for the Safe Stack protection to compiler-rt (see http://reviews.llvm.org/D6094 for the detailed description of the Safe Stack). This patch is our implementation of the safe stack on top of compiler-rt. The patch adds basic runtime support for the safe stack to compiler-rt that manages unsafe stack allocation/deallocation for each thread. Original patch by Volodymyr Kuznetsov and others at the Dependable Systems Lab at EPFL; updates and upstreaming by myself. Differential Revision: http://reviews.llvm.org/D6096 llvm-svn: 239763

# Build universal binary on APPLE.
[CMake] merge add_compiler_rt_runtime and add_compiler_rt_darwin_runtime into a single function Summary: This refactoring moves much of the Apple-specific behavior into a function in AddCompilerRT. The next cleanup patch will remove more of the if(APPLE) checks in the outlying CMakeLists. This patch adds a bunch of new functionality to add_compiler_rt_runtime so that the target names don't need to be reconstructed outside the call. It also updates some of the call sites to exercise the new functionality, but does not update all uses fully. Subsequent patches will further update call sites and move to using the new features.

[sanitizer] Implement logging to syslog. Previously, Android target had a logic of duplicating all sanitizer output to logcat. This change extends it to all posix platforms via the use of syslog, controlled by log_to_syslog flag. Enabled by default on Android, off everywhere else. A bit of cmake magic is required to allow Printf() to call a libc function. I'm adding a stub implementation to support no-libc builds like dfsan and safestack. This is a second attempt. I believe I've fixed all the issues that prompted the revert: Mac build, and all kinds of non-CMake builds (there are 3 of those). llvm-svn: 243051
