Change 636428c enabled BlockingRegion hooks for pthread_once(). Unfortunately this seems to cause crashes on Mac OS X which uses pthread_once() from locations that seem to result in crashes: | ThreadSanitizer:DEADLYSIGNAL | ==31465==ERROR: ThreadSanitizer: stack-overflow on address 0x7ffee73fffd8 (pc 0x00010807fd2a bp 0x7ffee7400050 sp 0x7ffee73fffb0 T93815) | #0 __tsan::MetaMap::GetSync(__tsan::ThreadState*, unsigned long, unsigned long, bool, bool) tsan_sync.cpp:195 (libclang_rt.tsan_osx_dynamic.dylib:x86_64+0x78d2a) | #1 __tsan::MutexPreLock(__tsan::ThreadState*, unsigned long, unsigned long, unsigned int) tsan_rtl_mutex.cpp:143 (libclang_rt.tsan_osx_dynamic.dylib:x86_64+0x6cefc) | #2 wrap_pthread_mutex_lock sanitizer_common_interceptors.inc:4240 (libclang_rt.tsan_osx_dynamic.dylib:x86_64+0x3dae0) | #3 flockfile <null>:2 (libsystem_c.dylib:x86_64+0x38a69) | #4 puts <null>:2 (libsystem_c.dylib:x86_64+0x3f69b) | #5 wrap_puts sanitizer_common_interceptors.inc (libclang_rt.tsan_osx_dynamic.dylib:x86_64+0x34d83) | #6 __tsan::OnPotentiallyBlockingRegionBegin() cxa_guard_acquire.cpp:8 (foo:x86_64+0x100000e48) | #7 wrap_pthread_once tsan_interceptors_posix.cpp:1512 (libclang_rt.tsan_osx_dynamic.dylib:x86_64+0x2f6e6) From the stack trace it can be seen that the caller is unknown, and the resulting stack-overflow seems to indicate that whoever the caller is does not have enough stack space or otherwise is running in a limited environment not yet ready for full instrumentation. Fix it by reverting behaviour on Mac OS X to not call BlockingRegion hooks from pthread_once(). Reported-by: azharudd Reviewed By: glider Differential Revision: https://reviews.llvm.org/D108305

This patch 1. aligns these extensions with SYCL 2020 [section #6 in the spec]: - Enqueue barrier [SYCL_EXT_INTEL_ENQUEUE_BARRIER] - Level Zero backend [SYCL_EXT_ONEAPI_BACKEND_LEVEL_ZERO] - Local memory [SYCL_EXT_ONEAPI_LOCAL_MEMORY] - mem_channel property [SYCL_EXT_INTEL_MEM_CHANNEL_PROPERTY] - USM address spaces [SYCL_EXT_INTEL_USM_ADDRESS_SPACES] 2. deprecates these extensions: - sycl::detail::bit_cast [SYCL_INTEL_bitcast] 3. changes the location of these extensions: - sycl::ext::intel::online_compiler moves to sycl::ext::intel::experimental. sycl::ext::intel::online_compiler is deprecated.

Although THREADLOCAL variables are supported on Darwin they cannot be used very early on during process init (before dyld has set it up). Unfortunately the checked lock is used before dyld has setup TLS leading to an abort call (`_tlv_boostrap()` is never supposed to be called at runtime). To avoid this problem `SANITIZER_CHECK_DEADLOCKS` is now disabled on Darwin platforms. This fixes running TSan tests (an possibly other Sanitizers) when `COMPILER_RT_DEBUG=ON`. For reference the crashing backtrace looks like this: ``` * thread #1, stop reason = signal SIGABRT * frame #0: 0x00000002044da0ae dyld`__abort_with_payload + 10 frame #1: 0x00000002044f01af dyld`abort_with_payload_wrapper_internal + 80 frame #2: 0x00000002044f01e1 dyld`abort_with_payload + 9 frame #3: 0x000000010c989060 dyld_sim`abort_with_payload + 26 frame #4: 0x000000010c94908b dyld_sim`dyld4::halt(char const*) + 375 frame #5: 0x000000010c988f5c dyld_sim`abort + 16 frame #6: 0x000000010c96104f dyld_sim`dyld4::APIs::_tlv_bootstrap() + 9 frame #7: 0x000000010cd8d6d2 libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::CheckedMutex::LockImpl(this=<unavailable>, pc=<unavailable>) at sanitizer_mutex.cpp:218:58 [opt] frame #8: 0x000000010cd8a0f7 libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::Mutex::Lock() [inlined] __sanitizer::CheckedMutex::Lock(this=0x000000010d733c90) at sanitizer_mutex.h:124:5 [opt] frame #9: 0x000000010cd8a0ee libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::Mutex::Lock(this=0x000000010d733c90) at sanitizer_mutex.h:162:19 [opt] frame #10: 0x000000010cd8a0bf libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::GenericScopedLock<__sanitizer::Mutex>::GenericScopedLock(this=0x000000030c7479a8, mu=<unavailable>) at sanitizer_mutex.h:364:10 [opt] frame #11: 0x000000010cd89819 libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::GenericScopedLock<__sanitizer::Mutex>::GenericScopedLock(this=0x000000030c7479a8, mu=<unavailable>) at sanitizer_mutex.h:363:67 [opt] frame #12: 0x000000010cd8985b libclang_rt.tsan_iossim_dynamic.dylib`__sanitizer::LibIgnore::OnLibraryLoaded(this=0x000000010d72f480, name=0x0000000000000000) at sanitizer_libignore.cpp:39:8 [opt] frame #13: 0x000000010cda7aaa libclang_rt.tsan_iossim_dynamic.dylib`__tsan::InitializeLibIgnore() at tsan_interceptors_posix.cpp:219:16 [opt] frame #14: 0x000000010cdce0bb libclang_rt.tsan_iossim_dynamic.dylib`__tsan::Initialize(thr=0x0000000110141400) at tsan_rtl.cpp:403:3 [opt] frame #15: 0x000000010cda7b8e libclang_rt.tsan_iossim_dynamic.dylib`__tsan::ScopedInterceptor::ScopedInterceptor(__tsan::ThreadState*, char const*, unsigned long) [inlined] __tsan::LazyInitialize(thr=0x0000000110141400) at tsan_rtl.h:665:5 [opt] frame #16: 0x000000010cda7b86 libclang_rt.tsan_iossim_dynamic.dylib`__tsan::ScopedInterceptor::ScopedInterceptor(this=0x000000030c747af8, thr=0x0000000110141400, fname=<unavailable>, pc=4568918787) at tsan_interceptors_posix.cpp:247:3 [opt] frame #17: 0x000000010cda7bb9 libclang_rt.tsan_iossim_dynamic.dylib`__tsan::ScopedInterceptor::ScopedInterceptor(this=0x000000030c747af8, thr=<unavailable>, fname=<unavailable>, pc=<unavailable>) at tsan_interceptors_posix.cpp:246:59 [opt] frame #18: 0x000000010cdb72b7 libclang_rt.tsan_iossim_dynamic.dylib`::wrap_strlcpy(dst="\xd2", src="0xd1d398d1bb0a007b", size=20) at sanitizer_common_interceptors.inc:7386:3 [opt] frame #19: 0x0000000110542b03 libsystem_c.dylib`__guard_setup + 140 frame #20: 0x00000001104f8ab4 libsystem_c.dylib`_libc_initializer + 65 ... ``` rdar://83723445 Differential Revision: https://reviews.llvm.org/D111243
