[SPIR-V] ThreadSanitizer tests crashes when SYCL is running with the LLVM SPIR-V backend in PVC #160602
Description
The following 9 SYCL E2E tests in ThreadSanitizer fail when they are running with LLVM SPIR-V backend on PVC machine.
ThreadSanitizer/aot/gpu.cpp
ThreadSanitizer/check_buffer.cpp
ThreadSanitizer/check_device_global.cpp
ThreadSanitizer/check_device_usm.cpp
ThreadSanitizer/check_host_usm.cpp
ThreadSanitizer/check_shared_usm.cpp
ThreadSanitizer/check_sub_buffer.cpp
ThreadSanitizer/group_local_memory.cpp
ThreadSanitizer/local_accessor.cpp
The following command used to run the tests.
build/bin/llvm-lit --param sycl_devices=level_zero:gpu --param dpcpp_compiler=$(which clang++) -v --param spirv-backend=True sycl/test-e2e/ThreadSanitizer
An example of the failure is as below. This failure is given by running ThreadSanitizer/check_device_global.cpp with SPIR-V Backend, and the other tests fail with the same issue as well.
