WebApr 30, 2024 · A summary of the paper BinRec: Dynamic Binary Lifting and Recompilation presented at EuroSys'20. BinRec is novel tool for binary lifting and recompilation which uses dynamic techniques to generate new binaries, in contrast to existing biniary recompilers like McSema and Rev.Ng which use static analysis and heuristic techniques … Binary Lifting is a dynamic programming approach where we pre-compute an array memo [1, n] [1, log (n)] where memo [i] [j] contains 2^j-th ancestor of node i. For computing the values of memo [] [], the following recursion may be used memo state: memo [i] [j] = i-th node’s 2^ (j)th ancestor in the path memo initialization:
