* Add runtime support for __cpu_model (__builtin_cpu_supports)Alina Sbirlea2016-07-082-1/+771
| | | | | | | | | | | | | | | | | | | Summary: This aims to add support for __cpu_model and address Bug 25510. It uses the code from lib/Support/Host.cpp for cpu detection, and creates __cpu_model with that info. Tested on OSX, it builts successfully, but the current version does *not* resolve Bug 25510. The __cpu_model symbol is present in the library but it only gets loaded with -all_load. This patch will not land until this issue is clarified. Built on Linux as well (though libgcc is the default). The use of "asm" required -std=gnu99, hence the cmake change. Corrections on better addressing this are welcome. Note: See additional comments on D20988 (committed as r271921).

* [compiler-rt] Fix sanitizer memory allocator on win64.Etienne Bergeron2016-07-073-4/+13
| | | | | | | | | | | | | | | | | | | | | | | Summary: This patch is fixing unittests for sanitizer memory allocator. There was two issues: 1) The VirtualAlloc can't reserve twice a memory range. The memory space used by the SizeClass allocator is reserved with NoAccess and pages are commited on demand (using MmapFixedOrDie). 2) The address space is allocated using two VirtualAlloc calls. The first one for the memory space, the second one for the AdditionnalSpace (after). On windows, they need to be freed separately.

* [tsan] Avoid false positives with GCD data callbacksKuba Brecka2016-07-072-0/+62
| | | | | | | | | | This patch adds synchronization between the creation of the GCD data object and destructor’s execution. It’s far from perfect, because ideally we’d want to synchronize the destruction of the last reference (via dispatch_release) and the destructor’s execution, but intercepting objc_release is problematic.

| | | | | | | | | | We already have interceptors for dispatch_source API (e.g. dispatch_source_set_event_handler), but they currently only handle submission synchronization. We also need to synchronize based on the target queue (serial, concurrent), in other words, we need to use dispatch_callback_wrap. This patch implements that.

| | | | | | | | | | | | original dispatch_once is used Because we use SCOPED_TSAN_INTERCEPTOR in the dispatch_once interceptor, the original dispatch_once can also be sometimes called (when ignores are enabled or when thr->is_inited is false). However the original dispatch_once function doesn’t expect to find “2” in the storage and it will spin forever (but we use “2” to indicate that the initialization is already done, so no waiting is necessary). This patch makes sure we never call the original dispatch_once.

* [compiler-rt] Fix passing debug information to unittest.Etienne Bergeron2016-06-292-0/+8
| | | | | | | | | | | | | | | | | | | | Summary: On windows, the debug information was not present in the unittest executables, which make them hard to debug. The Sanitizer Unittests are compiled with a local clang build. The link pass is also done by calling clang. This pass is adding the appropriate flags to bring the right debug information to these executables.

* [tsan] Stop extending the block’s lifetime in dispatch_group_asyncKuba Brecka2016-06-292-1/+46
| | | | | | | | | | The dispatch_group_async interceptor actually extends the lifetime of the executed block. This means the destructor of the block (and captured variables) is called *after* dispatch_group_leave, which changes the semantics of dispatch_group_async. This patch fixes that.

| | | | | | | | | | | | The triple must be parsed in base-config-ix.cmake. Otherwise, the cmake variable ANDROID won't be set and this will confuse cmake to build unsupported targets targeted for android.

| | | | | | | | | | Adding support for GCD barrier blocks in concurrent queues. This uses two sync object in the same way as read-write locks do. This also simplifies the use of dispatch groups (the notifications act as barrier blocks).

| | | | | | | | | | | | positives The non-barrier versions of OSAtomic* functions are semantically mo_relaxed, but the two variants (e.g. OSAtomicAdd32 and OSAtomicAdd32Barrier) are actually aliases of each other, and we cannot have different interceptors for them, because they're actually the same function. Thus, we have to stay conservative and treat the non-barrier versions as mo_acq_rel.

| | | | | | | | | | | | dynamic allocas, compiler-rt part See the bug report at https://github.com/google/sanitizers/issues/691. When a dynamic alloca has a constant size, ASan instrumentation will treat it as a regular dynamic alloca (insert calls to poison and unpoison), but the backend will turn it into a regular stack variable. The poisoning/unpoisoning is then broken. This patch will treat such allocas as static.

| | | | | | | | | | On OS X, we often get stack trace in a report that ends with a 0x0 frame. To get rid of it, let's trim the stack trace when we find a close-to-zero value, which is obviously not a valid PC.
