There is a idea floating around that LLVM and QEMU could be 
married. QEMU has sort-of-a-disassembler, where they generate 
little pieces of code and later let that code execute (it's 
actually a bit different, but hey, use the source). The idea was 
to replace that part with an LLVM IR generation. Then you can 
use standard LLVM optimization passes on this and/or run this 
code via JIT.

Anyway, the disassembler-part of QEMU is easy to rip out, for me 
it was easier than, say, the libbfd based disassemblers, which 
are highly optimized to produce human readable strings.
