2016-09-15[compiler-rt] Do not introduce __sanitizer namespace globallyAnna Zaks
The definitions in sanitizer_common may conflict with definitions from system headers because: The runtime includes the system headers after the project headers (as per LLVM coding guidelines). lib/sanitizer_common/sanitizer_internal_defs.h pollutes the namespace of everything defined after it, which is all/most of the sanitizer .h and .cc files and the included system headers with: using namespace __sanitizer; // NOLINT This patch solves the problem by introducing the namespace only within the sanitizer namespaces as proposed by Dmitry.

2016-08-26[CMake] Connect Compiler-RT targets to LLVM Runtimes directoryChris Bieneman
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). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@279863 91177308-0d34-0410-b5e6-96231b3b80d8
2016-07-11[compiler-rt] Fix VisualStudio virtual folders layoutEtienne Bergeron
Summary: This patch is a refactoring of the way cmake 'targets' are grouped. It won't affect non-UI cmake-generators. Clang/LLVM are using a structured way to group targets which ease navigation through Visual Studio UI. The Compiler-RT projects differ from the way Clang/LLVM are grouping targets. This patch doesn't contain behavior changes.

2015-12-11[compiler-rt] [safestack] Enable for aarch64Adhemerval Zanella
This patch enables the safestack for aarch64. The frontend already have it enabled on all supported architectures and no adjustment is required in llvm. The compiler-rt adjustments are basically add on the cmake configuration to enable the tests and fix the pagesize debug check by getting its value at runtime (since aarch64 has multiple pagesize depending of kernel configuration). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@255345 91177308-0d34-0410-b5e6-96231b3b80d8

2015-10-01[compiler-rt] Apply modernize-use-nullptr fixes in sanitizersVedant Kumar
- Trim spaces. - Use nullptr in place of 0 for pointer variables. - Use '!p' in place of 'p == 0' for null pointer checks. - Add blank lines to separate function definitions. - Add 'extern "C"' or 'namespace foo' comments after the appropriate closing brackets This is a continuation of work from 409b7b82. The focus here is on the various sanitizers (not sanitizer_common, as before). Patch by Eugene Zelenko!

2015-08-25[CMake] merge add_compiler_rt_runtime and add_compiler_rt_darwin_runtime ↵Chris Bieneman
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.

2015-07-23[sanitizer] Implement logging to syslog.Evgeniy Stepanov
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). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@243051 91177308-0d34-0410-b5e6-96231b3b80d8

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.
