Comment at: openmp/libomptarget/src/device.cpp:594
+ /// RAII to establish tool anchors before and after data allocation
+ OmptInterfaceTargetDataOpRAII TgtDataAlloc(
+ RTLDeviceID, Size, HstPtr, nullptr /* TgtPtr */, ompt_target_data_alloc);
----------------
I wonder if these RAII objects are constructed when OMPT support is not built, or if it is optimized away in such cases?
================
Comment at: openmp/libomptarget/src/device.cpp:624
+ /// RAII to establish tool anchors before and after data submit
+ OmptInterfaceTargetDataOpRAII TargetDataSubmitRAII(
+ RTLDeviceID, Size, HstPtrBegin, TgtPtrBegin,
----------------
In the asynchronous case, the lifetime of the RAII object is probably too short to account for the actual data transfer events.

Comment at: openmp/libomptarget/src/device.cpp:651
+ /// RAII to establish tool anchors before and after data retrieval
+ OmptInterfaceTargetDataOpRAII TargetDataRetrieve(
+ RTLDeviceID, Size, HstPtrBegin, TgtPtrBegin,
----------------
In the asynchronous case, the lifetime of the RAII object is probably too short to account for the actual data transfer events.
