[esan] EfficiencySanitizer base runtime library Summary: Adds the initial version of a runtime library for the new EfficiencySanitizer ("esan") family of tools. The library includes: + Slowpath code via callouts from the compiler instrumentation for each memory access. + Registration of atexit() to call finalization code. + Runtime option flags controlled by the environment variable ESAN_OPTIONS. The common sanitizer flags are supported such as verbosity and log_path. + An initial simple test. Still TODO: common code for libc interceptors and shadow memory mapping, and tool-specific code for shadow state updating.

# Build for the EfficiencySanitizer runtime support library.
[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

[esan] EfficiencySanitizer libc interceptors Summary: Adds libc interceptors to the runtime library for the new EfficiencySanitizer ("esan") family of tools.

Add working set base runtime library Summary: Adds the base runtime library for the working set tool. Adds slowpath code for updating the shadow memory.

[esan] Add handling of large stack size rlimits Summary: Adds detection of large stack size rlimits (over 1 TB or unlimited), which results in an mmap location that our shadow mapping does not support. We re-exec the application in this situation. Adds a test of this behavior. Adds general detection of mmap regions outside of our app regions. In the future we want to try to adaptively handle these but for now we abort. Moves the existing Linux-specific mmap code into a platform-specific file where the new rlimit code lives.

[esan] Add sideline itimer support Summary: Adds support for creating a separate thread for performing "sideline" actions on a periodic basis via an itimer. A new class SidelineThread implements this feature, exposing a sampling callback to the caller. Adds initial usage of sideline sampling to the working set tool. For now it simply prints the usage at each snapshot at verbosity level 1. Adds a test of this behavior. Adds a new option -record_snapshots to control whether we sample and a new option -sample_freq to control the periodicity of the sampling.

[esan] Intercept and chain signal handlers Summary: In preparation for fault-based shadow memory iteration, we add support for our own signal handler by adding app signal handler interception as well as chaining for SIGSEGV. This is done in a simple manner: we do not honor the app's alternate stack nor any sigaction flags for SIGSEGV. Adds a new test of transparency in app signal handling.

[sanitizer] Split Symbolizer/StackTraces from core RTSanitizerCommon Summary: Host symbolizer & stacktraces related code in their own RT: `RTSanitizerCommonSymbolizer`, which is "libcdep" by nature. Symbolizer & stacktraces specific code that used to live in common files is moved to a new file `sanitizer_symbolizer_report.cc` as is. The purpose of this is the enforce a separation between code that relies on symbolization and code that doesn't. This saves the inclusion of spurious code due to the interface functions with default visibility, and the extra data associated. The following sanitizers makefiles were modified & tested locally: - dfsan: doesn't require the new symbolizer RT - esan: requires it - hwasan: requires it - lsan: requires it - msan: requires it - safestack: doesn't require it - xray: doesn't require it - tsan: requires it - ubsan: requires it - ubsan_minimal: doesn't require it - scudo: requires it (but not for Fuchsia that has a minimal runtime) This was tested locally on Linux, Android, Fuchsia.
