[Openmp-commits] [PATCH] D96438: [OpenMP] Move synchronization into `__tgt_async_info`

================
Comment at: openmp/libomptarget/src/omptarget.cpp:647
+  if (AsyncInfo) {
+    Ret = AsyncInfo->synchronize();
     if (Ret != OFFLOAD_SUCCESS)
----------------
This will cause `synchronize` to be called twice: one here, and another when `AsyncInfo` is destroyed. For now `__tgt_rtl_synchronize` is not designed to be called on a same object twice because it will `assert(async_info_ptr->Queue)`, and every time we call `synchronize`, `Queue` will be set to `nullptr`.
