Lock-Free Shared Counters in C++20: An Architecture Note on std::atomic
A single std::atomic counter with relaxed increments is often enough for concurrent updates, but lock-free guarantees, memory ordering, and platform fallbacks decide whether the design holds in production.
cppBoost.Fiber: Replace Heavy OS Threads with Lightweight User‑Space Concurrency
Boost.Fiber lets you replace heavyweight OS threads with lightweight, user‑space fibers. Learn the core concepts, see a practical 10,000‑fiber counter example, and weigh the trade‑offs before adopting it in your C++ projects.
C++20 Concepts: Turning Template Ambiguity into Clearer APIs
Template functions often emit cryptic errors. C++20 Concepts let you declare type requirements, producing clear diagnostics. This post shows a concrete example, compares errors, and gives practical steps to adopt concepts.
How Clang's Sema Turned C++20 Concept Errors from Riddles into Readable Diagnostics
Older Clang reported only that a C++20 concept failed. Modern Sema walks the constraint tree and names the exact sub-expression that broke — here's what changed, with a worked example and the compile-time trade-offs.
semaAdopting C++20 Modules: A Practical Migration Guide for Medium-Sized Codebases
Step‑by‑step guide to adopting C++20 modules in a medium‑sized codebase: pick a leaf library, write module interface and implementation files, update consumers to import, configure CMake 3.28+, verify encapsulation and incremental build speedups, and recover with header shims if needed.
Clang Sema’s C++20 Concept Support: Constraint Checking, Satisfaction, and Overload Ranking
Discover how Clang’s semantic analyzer evaluates C++20 concepts, integrates constraint expressions, and performs partial ordering for overload resolution. A step‑by‑step example shows the AST nodes, compile‑time diagnostics, and practical limits to watch for.
Using Clang’s Sema to Catch C++20 Concept Violations Early
Learn how Clang’s Sema component diagnoses concept mismatches at compile time, giving clear messages that point to missing requirements and help you fix template errors faster.
How Clang’s Sema Simplifies C++20 Concepts: From Syntax to Diagnostics
Clang’s Sema now implements C++20 concepts, turning complex SFINAE into readable constraints. Learn how the semantic analyzer checks requirements, improves diagnostics, and what trade‑offs you should watch for.
