# Echo: Learning-based Matching Decompilation using Trusted Back Translation

> Echo iteratively generates source and compiler configurations, recompiles candidates, and uses assembly differences to guide configuration search and code refinement. It evaluates matching on function benchmarks and selected functions from a Mirai binary.

## Scope and limitations

Matching means equality of normalized function assembly under evaluated compilation settings, not byte-for-byte recovery of a whole executable. Tests cover selected x86 GCC/LLVM settings and 62 Mirai functions; passing finite harness tests is not a general equivalence proof. Long optimized functions and configurations outside the searched space remain limitations.

## Why it fits this collection

Adds compiler-feedback-driven matching decompilation while separating its matching criterion from test-only recovery.

## Publication and review notes

Latest reviewed version is arXiv v1. The Open Science section uses the placeholder anonymous.4open.science/xxxx, so no usable author artifact, model revision or code/data license was verified. The article uses the arXiv non-exclusive distribution license.
