@lunarood Not a reverse engineer, but I am the other two: Been an LLVM committer since 2008, implemented CHERI C, did the first Objective-C support in clang, and a few other things, so I can probably claim to be a compiler dev (though these days I do more managing of compiler devs than compiler dev work). Wrote the book on Xen, was elected to the FreeBSD core team twice, and am now maintainer of an RTOS (and do still write code, not just manage people who do).
I am also responsible for the ISA that our compiler and RTOS target. People who care about software should build their own hardware.
