v2026.4.2

Objeck Language v2026.4.2

JIT register cache (~3x perf), AI library refresh, S2F JIT fix, editor support, and more.

What's Changed

Performance

• JIT local variable register cache (AMD64 + ARM64) — ~3x speedup across all benchmarks. Keeps values in registers after store, avoids redundant reloads, evicts on demand.
• Fixed JIT S2F callback — String:ToFloat segfault on both AMD64 and ARM64 (wrong param count in JIT callback)

AI Libraries

• Gemini API — Gemini 2.5 Pro/Flash/Flash-Lite model constants, system instruction support for GenerateContent and Chat
• Ollama API — Configurable host (SetHost/GetHost), Options class (temperature/top_p/top_k), Tool class for function calling, structured output in Chat
• OpenAI API — New Embedding class for text embeddings, Models constants (GPT-4.1, O3, O3-mini, O4-mini, etc.)
• ML library — Fixed EuclideanDistance/StdDev bugs, added LinearRegression and LogisticRegression

Security & Networking

• Hardened JSON, JSON stream, and XML parsers against malformed input
• Hardened HTTPS client against null ReadLine on connection failures
• DTLS (Datagram TLS) support — DTLSSocket and DTLSSocketServer for secure UDP

Build & Tooling

• Link-time optimization (-flto=auto) across all GCC Makefiles
• ARM64 native CPU tuning (-mcpu=native) for RPi5 and Jetson Orin
• New editor setup guide (docs/editors.md) — VS Code, Vim, Emacs, Sublime, Kate
• DAP integration test suite (7 automated tests)
• Fixed all MSVC and GCC compiler warnings
