| * [Sanitizer] Cleanup {ASAN, MSAN}_INTERCEPT_FUNC[_VER] macroJulian Lettner2019-04-292-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | Note that this change is not strictly NFC since we add the `(&(name) != &WRAP(name)` part to the conditional for the `_VER` variant of the macro.

| | | | | | | | | | | | | | | | | | | | | | | | | | Symbol aliases are supported by all platforms that compiler-rt builtins target, and we can use these instead of function redirects to avoid the extra indirection.

| * [CMake] Don't modify `FUZZER_SUPPORTED_ARCH` is place.Dan Liew2019-04-281-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On a Darwin host we were modifying the `FUZZER_SUPPORTED_ARCH` in place which would strip out non-x86 architectures. This unhelpful if we want to use `FUZZER_SUPPORTED_ARCH` later. To fix this we introduce `FUZZER_TEST_ARCH` which is similar to what we have for for the other sanitizers. For non-Darwin host platforms `FUZZER_TEST_ARCH` is the same as `FUZZER_SUPPORTED_ARCH` but for Darwin host platforms we use `darwin_filter_host_archs(...)` as the previous code did. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@359394 91177308-0d34-0410-b5e6-96231b3b80d8

| * [asan_symbolize] Teach `asan_symbolize.py` to symbolicate using a module mapDan Liew2019-04-262-0/+274
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The use case here is to be able get the UUIDs of the modules that need to be symbolicated so that external plugins can see them. This information can be extracted from ASan reports if the `print_module_map` ASan option is enabled. Currently printing of the module map is only implemented on Darwin and so this is effectively a Darwin only feature right now. The module map hooks into symbolization using the new plugin infrastructure. A new hook in `AsanSymbolizerPlugInProxy` (and in `AsanSymbolizerPlugIn`) is also provided to allow external plugins to hook into the module look up process. This will allow external plugins to look up modules with knowledge of their UUID. The new plug-in is currently stored in the `asan_symbolize.py` script. We could potentially move this into a separate file in the future (to reduce clutter) if we can come up with a policy for where to search for plugins that should always get loaded. rdar://problem/49476995 Reviewers: kubamracek, yln, samsonov, dvyukov, vitalybuka Subscribers: #sanitizers, llvm-commits Tags: #llvm, #sanitizers Differential Revision: https://reviews.llvm.org/D60531 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@359322 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | platforms. The main problem here is that `-*-version_min=` was not being passed to the compiler when building test cases. This can cause problems when testing on devices running older OSs because Clang would previously assume the minimum deployment target is the the latest OS in the SDK which could be much newer than what the device is running. Previously the generated value looked like this: `-arch arm64 -isysroot <path_to_xcode>/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk` With this change it now looks like: `-arch arm64 -stdlib=libc++ -miphoneos-version-min=8.0 -isysroot <path_to_xcode>/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.1.sdk` This mirrors the setting of `config.target_cflags` on macOS. This change is made for ASan, LibFuzzer, TSan, and UBSan. To implement this a new `get_test_cflags_for_apple_platform()` function has been added that when given an Apple platform name and architecture returns a string containing the C compiler flags to use when building tests. This also calls a new helper function `is_valid_apple_platform()` that validates Apple platform names. rdar://problem/50124489 Differential Revision: https://reviews.llvm.org/D58578 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@359305 91177308-0d34-0410-b5e6-96231b3b80d8

| * [CMake] Add fuzzer as a component for runtime buildsChris Bieneman2019-04-191-0/+2
| | | | | | | | | | | | Calling `add_compiler_rt_component` sets up the component connection between runtime builds and the parent CMake configuration. Adding this call allows specifying `fuzzer` as a `LLVM_RUNTIME_DISTRIBUTION_COMPONENT`. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@358780 91177308-0d34-0410-b5e6-96231b3b80d8

| * [asan_symbolize] Workaround bug in old Python 2 versions.Dan Liew2019-04-181-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change landed in r358657 broke some of the buildbots because they use an older version of Python 2 that raises this error. ``` File "/Volumes/data/dev/llvm/upstream/master/src/projects/compiler-rt/lib/asan/scripts/asan_symbolize.py", line 509 exec(f.read(), globals_space, None) SyntaxError: unqualified exec is not allowed in function 'load_plugin_from_file' it contains a nested function with free variables ``` I can reproduce this problem when using Python 2.7.6. To workaround this some indirection has been added to prevent the broken (the line at fault would never be executed) SyntaxError error in old Python versions from being raised. rdar://problem/49476995 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@358682 91177308-0d34-0410-b5e6-96231b3b80d8
