Another big step toward a viable CMake build system for CompilerRT, ASan, and friends. This explicitly switches the CompilerRT CMake build to require CMake version 2.8.8 or newer which provides first-class support for "object" libraries which consist of a pile of '.o' files -- exactly what is desired for composing runtime libraries. I've gone ahead and switched to using this. I've also added the interception library which I missed initially. And I've added proper dependencies between the various libraries. With this, I'm able to build archives for asan that appear to contain all of the necessary .o files. The final tweak here is to start setting up the compile flags and macro defines expected by ASan and its helper libraries. These may not be entirely correct currently, they're based loosely on my reading of the old Makefiles. However, they can be tweaked more easily now that they're wired up properly. llvm-svn: 159129

[compiler-rt][XRay] re-submitting r276117, with fixes for build breakage due to extraneous and missing dependencies and attempts to build on unsupported OSes Summary: This is a fixed-up version of D21612, to address failure identified post-commit. Original commit description: This patch implements the initialisation and patching routines for the XRay runtime, along with the necessary trampolines for function entry/exit handling. For now we only define the basic hooks for allowing an implementation to define a handler that gets run on function entry/exit. We expose a minimal API for controlling the behaviour of the runtime (patching, cleanup, and setting the handler to invoke when instrumenting). Fixes include: - Gating XRay build to only Linux x86_64 and with the right dependencies in case it is the only library being built - Including <cstddef> to fix std::size_t issue Reviewers: kcc, rnk, echristo Subscribers: mehdi_amini, llvm-commits Differential Revision: https://reviews.llvm.org/D22611 llvm-svn: 276251

[CMake] Add options to control building sanitizers and builtins. There are situations where a user may want to build only the compiler-rt builtins, or only the sanitizer runtimes.

Reland "[compiler-rt] Simple crtbegin.o and crtend.o implementation" Clang relies on existence of certain symbols that are normally provided by crtbegin.o/crtend.o. However, LLVM does not currently provide implementation of these files, instead relying on either libgcc or implementations provided as part of the system. This change provides an initial implementation of crtbegin.o/crtend.o that can be used on system that don't provide crtbegin.o/crtend.o as part of their C library.

build: allow building a specific set of sanitizers Introduce a new CMake option `COMPILER_RT_SANITIZERS_TO_BUILD` which takes either a special token `all` (default) which will preserve the current behaviour or a CMake list of sanitizers to build. It will still perform the normal checks if the sanitizer is requested. It only permits a further means to exclude a particular sanitizer. This gives finer grained control than `COMPILER_RT_BUILD_SANITIZERS` which only gives an all or nothing control. llvm-svn: 279253

[scudo] Initial standalone skeleton check-in Summary: This is the initial check-in for the Standalone version of Scudo. The project is initially going to live in scudo/standalone then will replace scudo. See http://lists.llvm.org/pipermail/llvm-dev/2019-January/129113.html for details. This initial CL is meant to lay out the project structure, of both code & tests, providing a minimal amount of functionalities, namely various definitions, some atomic helpers and an intrusive list. (empty.cc is just here to have a compilation unit, but will go away in the upcoming CLs). Initial support is restricted to Linux i386 & x86_64 in make files and will be extended once things land & work. We will grow organically from here, adding functionalities in limited amounts.

scudo: Add support for diagnosing memory errors when memory tagging is enabled. Introduce a function __scudo_get_error_info() that may be called to interpret a crash resulting from a memory error, potentially in another process, given information extracted from the crashing process. The crash may be interpreted as a use-after-free, buffer overflow or buffer underflow. Also introduce a feature to optionally record a stack trace for each allocation and deallocation. If this feature is enabled, a stack trace for the allocation and (if applicable) the deallocation will also be available via __scudo_get_error_info().
