2021-06-07cxa_guard: avoid sys/syscall.h and SYS_gettidRyan Prichard
Avoid including sys/syscall.h on Android Trusty, because sys/syscall.h tries to include bits/syscall.h, which doesn't exist. Detect this situation using _LIBCXXABI_HAS_NO_THREADS, which Trust seems to define, and if there are no threads, then SYS_gettid isn't needed. Disable the SYS_gettid call for Bionic, because some Android processes have a seccomp filter blocking gettid.

2021-06-03Rewrite cxa guard implementation.Eric Fiselier
This patch does three main things: (1) It re-writes the cxa guard implementation to make it testable. (2) Adds support for recursive init detection on non-apple platforms. (3) It adds a futex based implementation. The futex based implementation locks and notifies on a per-object basis, unlike the current implementation which uses a global lock for all objects. Once this patch settles I'll turn it on by default when supported. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@359060 91177308-0d34-0410-b5e6-96231b3b80d8 (cherry picked from commit 57e82af58dd4515ab4885f32273268f34f757101) Bug: http://b/189279320 Test: treehugger Change-Id: Id518751bb508319b8491929092ddac1d0ccb73ad

2021-06-03Further refactor cxa_guard.cppEric Fiselier
This patch is a part of a series of patches to cleanup our implementation of __cxa_acquire et al. No functionality change was intended. This patch does two primary things. It introduces the GuardObject class to abstract the reading and writing to the guard object. In future, it will be used to ensure atomic accesses are used when needed. It also introduces the GuardValue class used to represent values of the guard object. It is an abstraction to access and write to the various different bits of a guard. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@357804 91177308-0d34-0410-b5e6-96231b3b80d8 (cherry picked from commit 45dccfe519d6ff73a41212f4f673ebafb196d688) Bug: http://b/189279320 Test: treehugger Change-Id: Ida958365f627587e353ab74dd0c8d74c8f36deaf
2021-06-03Create RAII lock guard for global initialization lock.Eric Fiselier
This patch is a part of a series of cleanups to cxa_guard.cpp. It should introduce no functionality change. This patch refactors the use of the global mutex and condvar into a RAII lock guard class. This improves correctness (since unlocks can't be forgotten). It also allows the unification of the non-threading and threading implementations. git-svn-id: https://llvm.org/svn/llvm-project/libcxxabi/trunk@357669 91177308-0d34-0410-b5e6-96231b3b80d8 (cherry picked from commit 43cb674684655c8ca907f814e90c65b3ea5b9106) Bug: http://b/189279320 Test: treehugger Change-Id: Ied307fc69e1ba563e5cb76e454084f9c5827e2d3
