Most of the new inspection logic is in Remote Mirror. New code in swift-inspect calls the new Remote Mirror functions and formats the resulting information for display. Specific Remote Mirror changes: * Add a call to check if a given metadata is an actor. * Add calls to get information about actors and tasks. * Add a `readObj` call to MemoryReader that combines the read and the cast, greatly simplifying code chasing pointers in the remote process. * Add a generalized facility to the C shims that can allocate a temporary object that remains valid until at least the next call, which is used to return various temporary arrays from the new calls. Remove the existing `lastString` and `lastChunks` member variables in favor of this new facility. Swift-inspect changes: * Add a new dump-concurrency command. * Add a new `ConcurrencyDumper.swift` file with the implementation. The dumper needs to do some additional work with the results from Remote Mirror to build up the task tree and this keeps it all organized. * Extend `Inspector` to query the target's threads and fetch each thread's current task. Concurrency runtime changes: * Add `_swift_concurrency_debug` variables pointing to the various future adapters. Remote Mirror uses these to provide a better view of a tasks's resume pointer. rdar://85231338

// Ensure that we do not export any weak symbols from the dylibs.
|
|
//
|
|
// Weak symbols require additional work from the loader to resolve the symbol at
|
|
// load time and can cause ODR violations as well as unexpected symbol
|
|
// satisfaction because the weak symbol may be used from a separate module.
|
|
|
|
// NOTE: this test is fragile. It is dependent on the specifics of the GNU C++
|
|
// runtime. The C++ headers from the runtime explicitly force the weak symbols
|
|
// to be publicly visible without allowing the user to control the visibility.
|
|
// We explicitly filter out the ones that we see being leaked after manually
|
|
// validating that they are being leaked because of the forceful nature of
|
|
// libstdc++.
