I was hacking on qemu last week, and wishing it wasn't written in C.
There's not much of a technical reason why it couldn't have been
written in a higher level language. Bitfield manipulation would be
more painful unless there was a bitstring-like preprocessor added.
The real reason to use C was to get wider development support. Qemu
also happens to be security critical (all those hacked up C device
emulations offer exploit possibilities for the guests). And it has
frequent vulnerabilities. Go figure ...
