[LLVMdev] bytecode

[Robert L. Bocchino Jr.]

Yes, that's right.  If you change the bytecode format, you need to 
rebuild your LLVM tree (which will rebuild the runtime libraries), and 
then reinstall the libraries.  To do this, run

make -C runtime install-bytecode

from your LLVM object directory.
