Claims a way to make compiler optimizations preserve security-relevant intermediate state by adding opaque observations and an opacification mechanism that enforces a happens‑before partial order. Implements it in Clang/LLVM by changing two LLVM hooks and emitting DWARF events. Validates on nine crypto and control‑flow protection benchmarks across ARM and x86, reporting nontrivial speedups versus unoptimized code and faster results than an IO‑barrier approach on several tests.
