v4.2.1: SHA-256 for JS, Swift, Go 🫆

on GitHub

Exposing SHA-256 to GoLang was tricky. Clang worked fine. GCC failed. It turned out that GCC was too shy about inlining my code, resulting in excessive stack space usage... Now, JavaScript, Swift, and GoLang bindings all support incremental SHA-256 procedures 🥳. Thanks to @MarekKnapek for reducing the stack memory usage of the serial SHA variant!

Moreover, thanks to @laurenspriem for highlighting the SIGILL when probing ID registers on older Arm CPUs. I've now guarded first mrs probes with signal handlers. Ugly solution, but it may work 😅 I've also improved the capability detection code on Arm-based Windows machines, using the OS-specific <processthreadsapi.h> functionality, so now not only pure NEON, but also NEON+SHA+AES kernels, should be dispatched just fine!

Thanks to @ashbob999, StringZilla is also getting more stable Windows builds and stringzilla_bare coverage in our CI 🦺
