Meta Garbage Collection: Using OCaml's GC to GC Rust
a day ago
- Soteria Rust, a symbolic execution tool, experienced quadratic slowdown due to its Tree Borrows aliasing model when handling loops.
- The fix leverages OCaml's garbage collector to automatically remove unreachable tree nodes, using weak references and periodic major collections.
- This change achieved linear execution time and up to 10x speedup on benchmarks, with only about 40 lines of code.
- The approach highlights the benefit of deeply integrating with the host language (OCaml) for complex memory management tasks.
