7 years agoJIT: devirtualization support for EqualityComparer<T>.Default (#14125)
Andy Ayers [Wed, 27 Sep 2017 14:15:04 +0000 (07:15 -0700)]
JIT: devirtualization support for EqualityComparer<T>.Default (#14125)

Mark `EqualityComparer<T>.Default`'s getter as `[Intrinsic]` so
the jit knows there is something special about it. Extend the jit's
named intrinsic recognizer to recognize this method.

Add a new jit interface method to determine the exact type returned
by `EqualityComparer<T>.Default`, given `T`. Compute the return type by
mirroring the logic used in the actual implementation. Bail out when
`T` is not final as those cases won't simplify down much and lead to
code bloat.

Invoke this interface method when trying to devirtualize calls where
the 'this' object in the call comes from `EqualityComparer<T>.Default`.

The devirtualized methods can then be inlined. Since the specific comparer
`Equal` and `GetHashCode` methods look more complicated in IL than they
really are, mark them with AggressiveInlining attributes.

If devirtualization and inlining happen, it is quite likely that the value
of the comparer object itself is not used in the body of the comparer. This
value comes from a static field cache on the comparer helper.

When the comparer value is ignored, the jit removes the field access since it
is non-faulting. It also removes the the class init helper that is there to
ensure that the (no-longer accessed) field is properly initialized. This helper
has relatively high overhead even in the fast case where the class has been
initialized aready.

Add a perf test.

Closes #6688.

    - x86: Similarly to x64, the compiled functions are pushing and popping 2-3 additional registers in the hottest fast paths.
    - I believe this is the main remaining gap and PGO is not helping with this

Avoid async method delegate allocation

Previously when a task-returning async method would yield for the first time, there would be four allocations: the task, the state machine object boxed to the heap, a context "runner" object, and a delegate that points to the boxed state machine's MoveNext method.  A recent PR changed this to avoid the separate box object and the runner, but that still left the task and the delegate.

This PR avoids the delegate as well in a common case.  For async methods that only ever await Task/Task`1, that aren't using a custom sync context/scheduler, and for which tracing isn't enabled, we know the inner workings of both the builder and the awaiter and can thus bypass the awaiter's pattern APIs; instead of creating the delegate that gets passed to the awaiter and then stored in the wrapped task's continuation slot/list, we can instead just store the boxed state machine directly in the slot/list.

Improve thread pool worker thread's spinning for work

Closes https://github.com/dotnet/coreclr/issues/5928

Replaced UnfairSemaphore with a new implementation in CLRLifoSemaphore
- UnfairSemaphore had a some benefits:
  - It tracked the number of spinners and avoids waking up waiters as long as the signal count can be satisfied by spinners
  - Since spinners get priority over waiters, that's the main "unfair" part of it that allows hot threads to remain hot and cold threads to remain cold. However, waiters are still released in FIFO order.
  - Spinning helps with throughput when incoming work is bursty
- All of the above benefits were retained in CLRLifoSemaphore and some were improved:
  - Similarly to UnfairSemaphore, the number of spinners are tracked and preferenced to avoid waking up waiters
  - For waiting, on Windows, a I/O completion port is used since it releases waiters in LIFO order. For Unix, added a prioritized wait function to the PAL to register waiters in reverse order for LIFO release behavior. This allows cold waiters to time out more easily since they will be used less frequently.
  - Similarly to SemaphoreSlim, the number of waiters that were signaled to wake but have not yet woken is tracked to help avoid waking up an excessive number of waiters
  - Added some YieldProcessorNormalized() calls to the spin loop. This avoids thrashing on Sleep(0) by adding a delay to the spin loop to allow it to be more effective when there are no threads to switch to, or the only other threads to switch to are other similar spinners.
  - Removed the processor count multiplier on the max spin count and retuned the default max spin count. The processor count multiplier was causing excessive CPU usage on machines with many processors.
