      The freeware version of IDA Pro has been upgraded from v5 to v7, and includes support for 64-bit (despite what the page description states) https://www.hex-rays.com/products/ida/support/download_freeware.shtml …

      Wonder if it's good enough for McSema @dguido ?

      No, IDA 7 Free does not have IDAPython which mcsema depends on. It might be possible since IDAPython is kind of an open source library.

          Plugin support is stripped out of IDA Free.

          Quite rational. Too bad though, there’s a lot of non-RE work being blocked here. Like, we didn’t realize how much GCC was blocking until LLVM.

          $400 for Binary Ninja is not too big an obstacle.

          You’d think, but the ecosystem constriction effect is real and almost certainly measurable.

          But for example, one could imagine a binary scrubbing sandbox that lifted code (even JITted!), validated it, and dropped it back to native or a safe native subset. Anything ambiguous just wouldn’t run. One could not imagine large numbers of users at $400 a head.

          BAP is free and is still the most powerful opensource program analysis framework for binary targets imo, author has discussed rewriting before, everything else you need for above scenario is already there including static checking engine.
