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.

No direct link to 2.8.8 doc): http://www.cmake.org/cmake/help/v3.0/module/CMakeParseArguments.html?highlight=cmake_parse_arguments Since I was already changing these calls, I changed ARCH and LIB into ARCHS and LIBS to make it more clear that they're lists of arguments.

2015-06-10[CMake] Cleanup add_compiler_rt_object_library to be platform-agnosticChris Bieneman
Summary: This change takes darwin-specific goop that was scattered around CMakeLists files and spread between add_compiler_rt_object_library and add_compiler_rt_darwin_object_library and moves it all under add_compiler_rt_object_library. The goal of this is to try to push platform handling as low in the utility functions as possible.

2015-05-29Add descriptive names to sanitizer entries in /proc/self/maps. Helps debugging.Evgeniy Stepanov
This is done by creating a named shared memory region, unlinking it and setting up a private (i.e. copy-on-write) mapping of that instead of a regular anonymous mapping. I've experimented with regular (sparse) files, but they can not be scaled to the size of MSan shadow mapping, at least on Linux/X86_64 and ext3 fs. Controlled by a common flag, decorate_proc_maps, disabled by default. This patch has a few shortcomings: * not all mappings are annotated, especially in TSan. * our handling of memset() of shadow via mmap() puts small anonymous mappings inside larger named mappings, which looks ugly and can, in theory, hit the mapping number limit. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@238621 91177308-0d34-0410-b5e6-96231b3b80d8

2015-04-01[UBSan] Embed UBSan into ASan runtime (compiler-rt part).Alexey Samsonov
Summary: Change the way we use ASan and UBSan together. Instead of keeping two separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on a platform, all UBSan sources are just compiled into dummy empty object files. UBSan initialization code (e.g. flag parsing) is directly called from ASan initialization, so we are able to enforce correct initialization order. This mirrors the approach we already use for ASan+LSan. This change doesn't modify the way we use standalone UBSan.

2015-01-23[compiler-rt] Ensure AsanInitFromRtl is called from a static initializer on ↵Kuba Brecka
OS X by using ASAN_DYNAMIC=1 The idea is to ensure that the ASan runtime gets initialized early (i.e. before other initializers/constructors) even when DYLD_INSERT_LIBRARIES is not used. In that case, the interceptors are not installed (on OS X, DYLD_INSERT_LIBRARIES is required for interceptors to work), and therefore ASan gets currently initialized quite late -- from the main executable's module initializer. The following issues are a consequence of this: https://code.google.com/p/address-sanitizer/issues/detail?id=363 https://code.google.com/p/address-sanitizer/issues/detail?id=357 Both of them are fixed with this patch.

2014-12-17[ASan] Always build shared ASan runtime on Linux.Alexey Samsonov
This commit changes the strategy for building shared ASan runtime and the way we test it: - COMPILER_RT_BUILD_SHARED_ASAN CMake option is removed. We now always build shared ASan runtime (it is the default on Android, Windows and Mac, and not the default on Linux and FreeBSD). - Platforms, which use static runtime by default now have "check-asan-dynamic" testsuite. This testsuite contains instrumented unit tests, and ASan lit tests, and runs them with shared ASan runtime. This testsuite is *not* a part of "check-asan" and *not* a part of "check-all", as adding 1000 more test cases, which duplicate existing ones is costly. However, you're welcome to add this command to your buildbot. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@224470 91177308-0d34-0410-b5e6-96231b3b80d8

Change the LC_ID_DYLIB of ASan's dynamic libraries on OS X to be set to "@rpath/libclang_rt.asan_osx_dynamic.dylib" and similarly for iossim. Clang driver then sets the "-rpath" to be the real path to where clang currently has the dylib (because clang uses the relative path to its current executable). This means if you move the compiler or install the binary release, -fsanitize=address will link to the proper library.
