- 4Hacker News·8/10/2026researchTail-call optimization in C is now practical in GCC and Clang
The post argues that tail-call optimization in C was historically limited by calling-convention constraints and was not broadly available in older compilers. It notes that modern GCC and Clang can now perform the kind of tail calls needed for interpreter dispatch, enabling techniques such as direct-threaded code and large-scale snippet generation. The discussion cites Gforth and WebAssembly interpreter implementations as examples of why this matters.
- 5Hacker News·7/11/2026researchBranchless quicksort gets faster with compiler-friendly style
The article shows that modern compilers, especially Clang, can generate fast branch-free code for optimized Quicksort when the implementation is written in a specific style. It demonstrates sorting-network-based macros and branchless compare-and-swap patterns as a way to influence optimization results.
