Compiler Intent,Proven End-To-End

X-Lang combines explicit semantic contracts, translation validation, and advisor-driven diagnostics to push beyond conservative heuristics while preserving correctness.

Research Overview

Semantic Contracts

Program intent is explicit, checkable, and consumable by lowering passes.

Translation Validation

Lean and Alive2 provide correctness guarantees across semantic and IR layers.

Actionable Advice

x-advisor catches negative synergy and ships practical remediations before runtime.

@layout(SoA)

Transforms Array-of-Structures into Structure-of-Arrays for contiguous access and stronger auto-vectorization.
