Prevent lldb from crashing when multiple threads are concurrently accessing the SB API with reproducer capture enabled. The API instrumentation records both the input arguments and the return value, but it cannot block for the duration of the API call. Therefore we introduce a sequence number that allows to to correlate the function with its result and add locking to ensure those two parts are emitted atomically. Using the sequence number, we can detect situations where the return value does not succeed the function call, in which case we print an error saying that concurrency is not (currently) supported. In the future we might attempt to be smarter and read ahead until we've found the return value matching the current call. Differential revision: https://reviews.llvm.org/D92820 |
