1. Not rebasing our fork of QEMU for years has put us in a bad spot. But just today a member of our team managed to lift stuff with the latest QEMU. And he has also been able to lift Qualcomm Hexagon code, for which we helped to add support in QEMU. Eventually we'll be the first proper Hexagon decompiler :)
2. Focusing too much on QEMU led our frontend to be tightly coupled with QEMU. It will now take some effort to enable support for additional frontends, non-QEMU based. But not impossible: our idea is to let user add support for a new architecture by defining, in C, a struct for the CPU state and a bunch of functions acting on it. That's it. No need to learn any internal representation.
tl;dr QEMU was a great choice, it worked so well that we didn't work on that part of the codebase for too much time and now there's some technical debt there. But we're addressing it.
