Code-size optimisation for top-level indirections (#7308) Top-level indirections are often generated when there is a cast, e.g. foo :: T foo = bar `cast` (some coercion) For these we were generating a full-blown CAF, which is a fair chunk of code. This patch makes these indirections generate a single IND_STATIC closure (4 words) instead. This is exactly what the CAF would evaluate to eventually anyway, we're just shortcutting the whole process.

Implement threadDelay with the new Windows IO manager
2:15 AM Changeset in base [3f5ad30]windows-iocp by Joey Adams <joeyadams3.14159@…>
Add GHC.Event.Windows This is an IO manager for Windows, using IO completion ports. It is loosely modeled after GHC.Event, and even uses a few of its components (PSQ, IntMap, Unique). It is named GHC.Event.Windows, rather than GHC.Event.IOCP, to suggest the possibility of additional facilities not related to IOCP, such as RegisterWaitForSingleObject.

1:12 PM Changeset in base [b107946]windows-iocp by Joey Adams <joeyadams3.14159@…>
Add forkOSMasked to GHC.Conc.Sync Also, make rtsSupportsBoundThreads an unsafe foreign import, and move its definition to GHC.Conc.Sync. This breaks an import cycle, as the new Windows I/O manager will (likely) need forkOS. Importing it from Control.Concurrent produces a cycle: IO manager -> Control.Concurrent -> GHC.Conc.IO -> IO manager. forkOSMasked is defined in GHC.Conc.Sync, which has much fewer transitive dependencies. forkOSMasked is intended to be internal. That's why it's exported by GHC.Conc.Sync but not by Control.Concurrent.

GHC.Windows: more error support (guards, system error strings) This changes the output of throwGetLastError to include the system error message, rather than the message of our fictitious errno. It also adds several definitions to GHC.Windows, mostly from the Win32 package. The exceptions are: * getErrorMessage: returns a String, unlike in System.Win32.Types, where it returns an LPWSTR. * errCodeToIOError: new * c_maperrno_func: new

Add a write barrier for TVAR closures This improves GC performance when there are a lot of TVars in the heap. For instance, a TChan with a lot of elements causes a massive GC drag without this patch. There's more to do - several other STM closure types don't have write barriers, so GC performance when there are a lot of threads blocked on STM isn't great. But fixing the problem for TVar is a good start.
