2025-08-20	[clang][SYCL] Add sycl_external attribute and restrict emitting device code ↵	schittir
	(#140282) This patch is part of the upstreaming effort for supporting SYCL language front end. It makes the following changes: 1. Adds sycl_external attribute for functions with external linkage, which is intended for use to implement the SYCL_EXTERNAL macro as specified by the SYCL 2020 specification 2. Adds checks to avoid emitting device code when sycl_external and sycl_kernel_entry_point attributes are not enabled 3. Fixes test failures caused by the above changes This patch is missing diagnostics for the following diagnostics listed in the SYCL 2020 specification's section 5.10.1, which will be addressed in a subsequent PR: Functions that are declared using SYCL_EXTERNAL have the following additional restrictions beyond those imposed on other device functions: 1. If the SYCL backend does not support the generic address space then the function cannot use raw pointers as parameter or return types. Explicit pointer classes must be used instead; 2. The function cannot call group::parallel_for_work_item; 3. The function cannot be called from a parallel_for_work_group scope. In addition to that, the subsequent PR will also implement diagnostics for inline functions including virtual functions defined as inline. --------- Co-authored-by: Mariya Podchishchaeva <mariya.podchishchaeva@intel.com>

2023-03-30	[SYCL] Always set NoUnwind attribute for SYCL.	Harald van Dijk
	Like CUDA and OpenCL, the SYCL specification says that throwing and catching exceptions in device functions is not supported, so this change extends the logic for adding the NoUnwind attribute to SYCL. The existing convergent.cpp test, which tests that the convergent attribute is added to functions by default, is renamed and reused to test that the nounwind attribute is added by default. This test now has -fexceptions added to it, which the driver adds by default as well. The obvious question here is why not simply change the driver to remove -fexceptions. This change follows the direction given by the TODO comment because removing -fexceptions would also disable the __EXCEPTIONS macro, which should reflect whether exceptions are enabled on the host, rather than on the device, to avoid conflicts in types shared between host and device.
