  9. In case you were also unable to figure out from context exactly what McSema is: https://github.com/trailofbits/mcsema > McSema is an executable lifter. It translates ("lifts") executable binaries from native machine code to LLVM bitcode.

  19. It depends on what you are looking to achieve. If you take a look to e.g. McSema https://github.com/trailofbits/mcsema , these guys have been able to use LLVM to transform assembly back to LLVM intermediate representation (IR). The IR is…
