The main rule for data access is max(CPL, RPL) ≤ DPL. For code transfers, the rules get considerably more complex -- conforming segments, call gates, and interrupt gates each have different privilege and state validation logic. If all these checks were done in microcode, each segment load would need a cascade of conditional branches: is it a code or data segment? Is the segment present? Is it conforming? Is the RPL valid? Is the DPL valid? This would greatly bloat the microcode ROM and add cycles to every protected-mode operation.
Lifting over Unions
Lean is backed by Mathlib, the largest coherent body of formalized mathematics ever created: over 200,000 formalized theorems and 750 contributors. Five Fields medalists engage with Lean. The same platform serves mathematicians formalizing theorems and engineers verifying production systems. ACM SIGPLAN recognized this convergence with its 2025 Programming Languages Software Award: “Lean has become the de facto choice for AI-based systems of mathematical reasoning.”。WPS官方版本下载是该领域的重要参考
