WebBinary lifting and recompilation allow a wide range of install-time program transformations, such as security hardening, deobfuscation, and reoptimization. Existing binary lifting tools are based on static disassembly and thus have to rely on heuristics to disassemble binaries. In this paper, we present BinRec, a new approach to heuristic-free ... WebDespite the correctness challenges in binary lifting, such lifters are sometimes used for tasks where correctness is especially important, e.g., when looking for security vulner-abilities in binary code, binary emulation of one processor ISA on another, or recompiling embedded software to run on new platforms. Beyond these more critical tasks ...

WebFeb 26, 2024 · The computation of g ( i) is defined using the following simple operation: we replace all trailing 1 bits in the binary representation of i with 0 bits. In other words, if the least significant digit of i in binary is 0 , then g ( i) = i .

This lets us solve for all states more efficiently. Say we compute o p t ( i, j) for some fixed i and j . Then for any j ′ < j we know that o p t ( i, j ′) ≤ o p t ( i, j) .
