call_once and TSan
Hi, I'm trying to write a TSan interceptor for the C++11 call_once function. There are currently false positive reports, because the inner __call_once function is located in the (non-instrumented) libcxx library, and on macOS we can't expect the users to build their own instrumented libcxx. TSan already supports pthread_once and dispatch_once by having interceptors that re-implement the

Since Phabricator automatically closed http://reviews.llvm.org/D12761 <http://reviews.llvm.org/D12761>, I've created a new revision. The attached diff is a very a slightly modified version of your original patch ... I have wanted to reopen a Phabricator revision too many times already, but

[LLVMdev] Proposal: ASan debugging API
Hi, I would like to improve the debugging experience for ASan. The idea is to have a couple of useful commands in LLDB (probably implemented as Python scripts) that could help the user when they are debugging an ASan-enabled binary. We already have some debugging API (asan_interface.h): // Print the description of addr (useful when debugging in gdb). void __asan_describe_address(void

greendragon build noisy due to mmap_stress.cc
Hm, I tried to reproduce this as well, but unsuccessfully. From the crash report: EXC_I386_GPFLT means we’re dereferencing a non-canonical pointer, in this case “0x00486000000025df”. This happens at wrap_OSSpinLockLock+17, which is just after the prologue and just after calling cur_thread(). So I’d say it happens when we’re dereferencing the pointer returned by cur_thread(). On OS X, we’re
