2017-12-12[CMake] Support runtimes and monorepo layouts when looking for libcxxPetr Hosek
This also slightly refactors the code that's checking the directory presence which allows eliminating one unnecessary variable. Differential Revision: https://reviews.llvm.org/D40637 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@320446 91177308-0d34-0410-b5e6-96231b3b80d8
2017-12-06[TSan] Make more TSan interceptors symbolizer-aware.Alex Shlyapnikov
Summary: Switching the rest of intercepted allocs to InternalAlloc (well, except __libc_memalign) when current thread is 'in_symbolizer'. Symbolizer might (and does) use allocation functions other than malloc/calloc/realloc. posix_memalign is the one actually used, others switched just in case (since the failure is obscure and not obvious to diagnose).

2017-11-28Support the setjmp(3) family of functions in TSan/NetBSDKamil Rytarowski
Summary: This change adds support for the setjmp(3)/longjmp(3) family of functions on NetBSD. There are three types of them on NetBSD: - setjmp(3) / longjmp(3) - sigsetjmp(3) / sigsetjmp(3) - _setjmp(3) / _longjmp(3) Due to historical and compat reasons the symbol names are mangled: - setjmp -> __setjmp14 - longjmp -> __longjmp14 - sigsetjmp -> __sigsetjmp14 - siglongjmp -> __siglongjmp14 - _setjmp -> _setjmp - _longjmp -> _longjmp This leads to symbol renaming in the existing codebase. There is no such symbol as __sigsetjmp/__longsetjmp on NetBSD Add a comment that GNU-style executable stack note is not needed on NetBSD. The stack is not executable without it.

2017-11-20Handle NetBSD specific indirection of libpthread functionsKamil Rytarowski
Summary: Correct handling of libpthread(3) functions in TSan/NetBSD: - pthread_cond_init(3), - pthread_cond_signal(3), - pthread_cond_broadcast(3), - pthread_cond_wait(3), - pthread_cond_destroy(3), - pthread_mutex_init(3), - pthread_mutex_destroy(3), - pthread_mutex_trylock(3), - pthread_rwlock_init(3), - pthread_rwlock_destroy(3), - pthread_rwlock_rdlock(3), - pthread_rwlock_tryrdlock(3), - pthread_rwlock_wrlock(3), - pthread_rwlock_trywrlock(3), - pthread_rwlock_unlock(3), - pthread_once(3). Code out of the libpthread(3) context uses the libc symbols that are prefixed with __libc_, for example: __libc_cond_init. This caused that these functions were invisible to sanitizers on NetBSD. Intercept the libc-specific ones and add them as NetBSD-specific aliases for the common pthread(3) ones. NetBSD needs to intercept both functions, as the regularly named ones are used internally in libpthread(3).

2017-11-08Correct atexit(3) support in TSan/NetBSDKamil Rytarowski
Summary: The NetBSD specific implementation of cxa_atexit() does not preserve the 2nd argument if dso is equal to NULL. Changes: - Split paths of handling intercepted __cxa_atexit() and atexit(3). This affects all supported Operating Systems. - Add a local stack-like structure to hold the __cxa_atexit() context. atexit(3) is documented in the C standard as calling callback from the earliest to the oldest entry. This path also fixes potential ABI problem of passing an argument to a function from the atexit(3) callback mechanism. - Add new test to ensure LIFO style of atexit(3) callbacks: atexit3.cc Proposal to change the behavior of __cxa_atexit() in NetBSD has been rejected. With the above changes TSan/NetBSD with the current tsan_interceptors.cc can bootstrap into operation.

Summary: Stop using the Linux solution with pthread_key_create(3). This approach does not work on NetBSD, because calling the thread destructor is not the latest operation on a POSIX thread entity. NetBSD's libpthread still calls at least pthread_mutex_lock and pthread_mutex_unlock. Detect _lwp_exit(2) call as it is really the latest operation called from a detaching POSIX thread.

__tsan_mutex_linker_init behavior Add a new flag, _⁠_tsan_mutex_not_static, which has the opposite sense of _⁠_tsan_mutex_linker_init. When the new _⁠_tsan_mutex_not_static flag is passed to _⁠_tsan_mutex_destroy, tsan ignores the destruction unless the mutex was also created with the _⁠_tsan_mutex_not_static flag. This is useful for constructors that otherwise woud set _⁠_tsan_mutex_linker_init but cannot, because they are declared constexpr. Google has a custom mutex with two constructors, a "linker initialized" constructor that relies on zero-initialization and sets ⁠_⁠_tsan_mutex_linker_init, and a normal one which sets no tsan flags. The "linker initialized" constructor is morally constexpr, but we can't declare it constexpr because of the need to call into tsan as a side effect. With this new flag, the normal c'tor can set _⁠_tsan_mutex_not_static, the "linker initialized" constructor can rely on tsan's lazy initialization, and _⁠_tsan_mutex_destroy can still handle both cases correctly.

Given that cxx-abi may be the full libstdc++/libc++, it makes sense for it to be ahead of libc and libgcc, at least. The real motivation is Android, where in the arm32 NDK toolchain libstdc++.a is actually a linker script that tries to sneak LLVM's libunwind ahead of libgcc's. Wrong library order breaks unwinding.

2017-08-15[sanitizers CMake] NFC Refactor the logic for compiling and generating testsGeorge Karpenkov
into a function. Most CMake configuration under compiler-rt/lib/*/tests have almost-the-same-but-not-quite functions of the form add_X_[unit]tests for compiling and running the tests. Much of the logic is duplicated with minor variations across different sub-folders. This can harm productivity for multiple reasons: For newcomers, resulting CMake files are very large, hard to understand, and hide the intention of the code. Changes for enabling certain architectures end up being unnecessarily large, as they get duplicated across multiple folders. Adding new sub-projects requires more effort than it should, as a developer has to again copy-n-paste the configuration, and it's not even clear from which sub-project it should be copy-n-pasted. With this change the logic of compile-and-generate-a-set-of-tests is extracted into a function, which hopefully makes writing and reading CMake much easier.

Summary: `CheckForPvallocOverflow` was introduced with D35818 to detect when pvalloc would wrap when rounding up to the next multiple of the page size. Add this check to TSan's pvalloc implementation.

2017-07-28[sanitizers test CMake] further refactor testing CMake for tsanGeorge Karpenkov
TSan tests on Darwin first link all libraries into a static archive file. With this change, the linking is done once per all architecture, and previously the linking step was repeated per each architecture per each add_tsan_test call. Furthermore, the code is cleared up.

2017-07-28[sanitizer tests CMake] Factor out CMake logic for compiling sanitizer testsGeorge Karpenkov
Currently there's a large amount of CMake logic duplication for compiling sanitizer tests. If we add more sanitizers, the duplication will get even worse. This change factors out common compilation commands into a macro available to all sanitizers. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@309405 91177308-0d34-0410-b5e6-96231b3b80d8

This allows using the in tree version of libunwind and libc++abi which is useful when building a toolchain for different target.
