Moreover I think we should also add ECF_MALLOC (malloc attribute) because otherwise the allocated memory will not be considered as local. Extract from trans-mem.c: thread_private_new_memory() if (stmt && is_gimple_call (stmt) && gimple_call_flags (stmt) & ECF_MALLOC) /* Thread-local or transaction-local. */ ; else retval = mem_non_local; Thanks.
