Yes. AFAIK, currently QEMU disassembles source binary, converts
instructions to "ops" (which is something like direct C equivalents of
the instructions) and executes that "ops". 

The idea was to emit LLVM IR instead of that "ops". And after - use all
power of LLVM (JIT'ing, transformations, etc.).

These are "source" architectures, e.g. the architectures QEMU will
translate code from.
