It reports that Intel multiplications involving subnormals can be about 45 to 50 times slower than normal multiplications, while additions and subtractions remain at full speed. AMD Zen 5 performs much better in the tested workloads. ### Source excerpt We represent floating-point numbers using the IEEE standard. For very small numbers, the standard uses special subnormal numbers. Unfortunately, they have a reputation of making operations slow. Thus video game programmers and machine learning specialists sometimes avoid computing with subnormal numbers for performance. How slow are they? Let me measure. I wrote a small C++ ...

It explains that the retry mechanism appears to jump back to the start of the block without releasing resources, so it can leave the deadlock unresolved and potentially add more deadlocks. ### Source excerpt Kevin sends us an exception handler from C++. Let's see if we can spot what's going wrong: catch (Exception::Deadlock) { retry; } When we catch a deadlock happening, we retry. That's not a keyword in C++, and looking at how it's used, it has to be some kind of macro, and I suspect that the macro is hiding a goto underneath it. The real problem, though, is that we suspect we're in a deadlock situation. That means this thread is waiting on a resource held by another thread which is waiting for a resource held by this thread. Neither train may continue until the other has passed. So this retry only works if it releases the resource held by this thread (letting the deadlocking thread proceed). But does it? Not according ot Kevin. The code already had a pile of deadlocks in it, so they brought in a highly paid consultant to try and fix them by reordering access and tracing where mutexes were causing issues. This retry just jumps back up to the top of the block, without releasing any resources. It "seems the consultant wanted to add some deadlocks of their own," Kevin says.

The APIs can suspend storage-bound reads, allowing a small executor to run other ready tasks and maintain more storage queue depth without one blocked application thread per read. The feature targets throughput for I/O-bound point lookups rather than reducing individual device-read latency. ### Source excerpt A point lookup that misses RocksDB's block cache can spend most of its time waiting for storage. The traditional way to keep more reads in flight is to add threads. That works, but each outstanding read parks a thread, carries a stack, and adds context-switching overhead. RocksDB now has experimental asynchronous Get and MultiGet APIs backed by native C++ coroutines. When a read reaches storage, RocksDB can suspend the request, let its read-executor worker run another ready task, and resume the request when the filesystem reports completion. A small executor can therefore maintain more storage queue depth without requiring one blocked application thread per read. These APIs are available in RocksDB 11.10.0. This is primarily a throughput feature for I/O-bound point lookups. It does not make an individual device read faster. Its benefit comes from keeping the device busy and using CPU threads for runnable work. The API surface RocksDB exposes the new read path through two public interfaces: DB::GetAsync and DB::MultiGetAsync return immediately on the native path and report completion through AsyncCallback::OnComplete. CoroDB::CoGet and CoroDB::CoMultiGet return lazy folly::coro::Task objects. CoGet produces a Status; CoMultiGet fills the same per-key values and statuses as synchronous MultiGet. The callback APIs suit applications that do not expose Folly tasks at their boundaries. The CoroDB APIs let coroutine-based callers await RocksDB directly, avoiding an application-side callback-to-Baton adapter and its extra completion handoff. Native execution requires RocksDB to be built with Folly and USE_COROUTINES=1. Neither interface requires ReadOptions::async_io. That flag continues to control the older internal async-I/O optimizations for synchronous MultiGet and iterators. The task APIs are lazy: no read begins until a task is awaited or started. Both interfaces take pointer and reference parameters, so keep the DB, column-family handles, ReadOptions, keys and their ## Rust Function Overloading - Call for Experimentation DevFeed: [Rust Function Overloading - Call for Experimentation]() Original publisher: [Read original article]() Author: teor Published: 2026-08-19T00:00:00Z Content type: release Language: en Sources: [Inside Rust Blog]() Topics: [Rust](), [C++](), [Compiler](), [interoperability]() Tags: [c-plus-plus](), [compiler](), [interoperability](), [languages](), [rust](), [syntax]() ### AI overview The Rust Project is experimenting with function and method overloading for FFI bindings through the incomplete nightly "splat" compiler feature. The experiment aims to assess implementation complexity and improve interoperability with C++, while its design may change or be removed. ### Source excerpt In partnership with the Rust Foundation's Rust-C++ Interop Initiative, the Rust Project has been experimenting with function overloading for FFI bindings. This experiment is now at a stage where compiler and interop tool developers can start exploring function overloading. Stable Rust already supports a form of overloading using tuples and traits, but calling these overloaded functions looks strange, because the overloaded arguments have to be passed as a single tuple argument, like this: hypot((2.0, 3.0, 6.0)). Stable Rust also allows overloading of built-in operators with user-defined types, via traits like Add (the + operator) and Neg (the - value negation operator). We are running an unstable nightly Rust language experiment to answer questions like: How much overloading can we do with Rust's existing trait system? Could this help us call C++ from Rust ergonomically? In the tradition of yeet (to avoid bikeshedding), we are using basic syntax in the first stage of the experiment: the #[rustc_splat] attribute. Alternative syntaxes can be considered later, if the experiment generates useful outcomes. Experimental Function Overloading Rust nightly builds from 2026-07-31 onwards have experimental support for more ergonomic function and method overloading, using the incomplete "splat" compiler feature; if you're a compiler or interop tool developer, we encourage you to experiment with it! This experiment lets overloaded functions be called with separate arguments, like this: hypot(2.0, 3.0, 6.0). No double parentheses required! But type inference and type checking still happen as they would in a stable Rust overload. We are experimenting with splat to get a feel for the complexity of the implementation, and to see if it solves some language interoperability use cases. Like most Rust language experiments, this nightly feature has no RFC, and can change or be removed at any time. Experiment Design We expect the feature to change significantly in future, or to be replace ## C++29 -- начало. Встреча ISO C++ в Брно DevFeed: [C++29 -- начало.
