    8080In order to do this, we must solve the `branch displacement' problem---deciding how best to expand pseudojumps to labels in assembly language to machine code jumps.
    8181Clearly a correct but efficient strategy would be to expand all unconditional pseudojumps to the MCS-51's \texttt{LJMP} instruction, and all conditional pseudojumps to a set configuration of jumps using \texttt{LJMP} instructions; this is inefficient and a waste of valuable code memory space.
    82 Finding an efficient solution with this expansion process is not trivial, and is a well-known problem for those writing assemblers targetting RISC architectures (for instance, see~\cite{holmes:branch:2006}).

    8484To free the CerCo C compiler from having to consider complications relating to branch displacement, we have chosen to implement an optimising assembler, whose input language the compiler will target.
