  1. Also, #SymbolicExecution of even small #binaries is very slow and would only, probably, help for comparing binaries for the same (or compatible) architecture. And in order to compare binaries for the same architectures you have a myriad of different, not terribly slow, ways for doing #BinDiffing.

  2. Dear everyone in the academia (and maybe elsewhere) doing #bindiffing research: #SymbolicExecution does not work for comparing different architectures, unless you are using as input for your symbolic execution tool *decompiled code*.

    If you are using assembly or using an IR (Intermediate Representation) based on assembler (like Ghidra' p-code, IDA's microcode, LLVM's IR, etc), it will inevitably produce different outputs.

    Your best IR for #diffing is pseudo-code, the #decompiler's output.
