* [ASan] Add CMake configs for libclang_rt.asan_iossim_dynamic.dylib Alexander Potapenko2013-11-07
| | | | | | | | | | | CMake changes to build the ASan runtime for the iOS simulator. This is a universal library targeting the same architectures as the OSX ASan runtime does, thus the iossim version can't live in the same universal libclang_rt.asan_osx_dynamic.dylib The difference between the OSX and iossim builds is in the -mios-simulator-version-min and -ios_simulator_version_min flags that tell Clang to compile and link iossim code. The iossim runtime can only be built on a machine with both Xcode and the iOS Simulator SDK installed. If xcodebuild -version -sdk iphonesimulator Path returns a nonempty path, it is used when compiling and linking the iossim runtime. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194199 91177308-0d34-0410-b5e6-96231b3b80d8

* Properly generate lists of exported symbols for sanitizer runtimesAlexey Samsonov2013-08-27
| | | | | | | | | | This change adds a Python script that is invoked for the just-built sanitizer runtime to generate the list of exported symbols passed to the linker. By default, it contains interceptors and sanitizer interface functions, but can be extended with tool-specific lists. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@189356 91177308-0d34-0410-b5e6-96231b3b80d8

* [nolibc] Disable the GCC stack protector when building sanitizer runtimes.Peter Collingbourne2013-05-08
| | | | | | | | | | | | | | | | | | | This is the first in a sequence of changes designed to eliminate the libc dependency in sanitizer_common. The main motivation for these changes is to be able to provide an alternative for the current interceptor-based technique for instrumenting functions in libc. In this new technique, we compile libc with instrumentation. This has the potential advantages of being more accurate than interception and reducing the amount of custom code required for each libc function. As a side effect of this, we cannot depend on libc in the sanitizer runtime due to mutual dependency issues. This change disables the GCC stack protector, which introduces a libc dependency and is enabled by default in Ubuntu.

Now just-built Clang is used to: 1) compile instrumented sources (as before); 2) compile non-instrumented sources; 3) compile our own instrumented version of googletest; 4) link it all together using -fsanitize=address flag (instead of trying to copy linker behavior in CMake build rules).

* Relocate the external headers provided by ASan and the common sanitizerChandler Carruth2012-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | library. These headers are intended to be available to user code when built with AddressSanitizer (or one of the other sanitizer's in the future) to interface with the runtime library. As such, they form stable external C interfaces, and the headers shouldn't be located within the implementation. I've pulled them out into what seem like fairly obvious locations and names, but I'm wide open to further bikeshedding of these names and locations. I've updated the code and the build system to cope with the new locations, both CMake and Makefile. Please let me know if this breaks anyone's build. The eventual goal is to install these headers along side the Clang builtin headers when we build the ASan runtime and install it. My current thinking is to locate them at: <prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h <prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h <prefix>/lib/clang/X.Y/include/sanitizer/... But maybe others have different suggestions? Fixing the style of the #include between these headers at least unblocks experimentation with installing them as they now should work when installed in these locations. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@162822 91177308-0d34-0410-b5e6-96231b3b80d8
* Some flag cleanup for the sanitizer runtimes.Chandler Carruth2012-08-29
| | | | | | | | | | | | This hoists most of the CFLAGS into a common variable. It also adds detection for -Wno-c99-extensions and uses it to silence a pile of warnings. Finally, it switches to the proper flag -rdynamic.

* Add support for building the ASan instrumentation unit tests with theChandler Carruth2012-06-27
| | | | | | | | | | | | | | just-built Clang binary, and linking them against the just-built ASan runtime. This is *very* brittle. I expect it will require tweaking, and I've pro-actively disabled it on non-Unix builds and on cross-builds. It is also currently missing dependency edges on GoogleTest header files and a few other corner cases, but those can be fixed. This is the major milestone of a mini-bootstrap-like build of the unittest. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@159255 91177308-0d34-0410-b5e6-96231b3b80d8
* Another big step toward a viable CMake build system for CompilerRT,Chandler Carruth2012-06-25
| | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@159129 91177308-0d34-0410-b5e6-96231b3b80d8

* Initial, very rough cut at a new CMake build system for compiler-rt.Chandler Carruth2012-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some high-level notes: 1) An explicit goal is to support building compiler-rt as a subproject build, checked out into the projects/compiler-rt directory. There are many other possible ways of building the code here, but this is optimized for development on LLVM/Clang/compiler-rt, and incremental trial and testing of the toolchain. 2) The current support is targeted at Linux. I would love to see this generalized to other platforms, but for the sake of simplicity in testing, I'm focusing here first. Much of this patch was paired with Manuel, and I credit him with the majority of the work here. Some important caveats that I'll be working on in subsequent patches: 1) This uses the host compiler rather than using the just-built-clang. 2) Currently only x86 is supported. 3) Currently, none of the tests are built or run. 4) Uses CMake's builtin globbing which doesn't update correctly. 5) This is still turned off from LLVM's CMake build until these issues are addressed git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@154060 91177308-0d34-0410-b5e6-96231b3b80d8
