[SYCL] Fix linkage adjustment of kernels

AlexeySachkov · AlexeySachkov · commit 79bcea6b7646 · 2025-08-12T12:41:00.000+02:00
This patch resolves intel#19409 Two main changes were done: 1. Corrected method of detection that kernel is defined as an inline function. The original code detecting this was introduced in intel#338, but by some reason we looked into a headers-provided wrapper that calls a kernel instead of a kernel itself. Alongside with fixing this, a dedicated clang-level test was added to check this behavior 2. Fixed a bug introduced by incorrect conflict resolution (commit fcd95a9) with llvm/llvm-project#137882. Specifically, when deciding if a function (that is expected to be a SYCL kernel) linkage should be promoted to non-discardable we used to check for OpenCL kernel attribute. That attribute is not present in SYCL headers and therefore was only generated for actual SYCL kernels emitted by front-end. However, with kernel attributes unified, we now promote linkage of non-kernel wrapper function that has `sycl_kernel` attribute attached to it explicitly by SYCL headers. The fix here is to only react to the kernel attribute if it was added implicitly, to preserve original behavior.
