A binary translator examines binary code for a source machine, optionally builds an intermediate representation, and generates code for a target machine. Understanding what to do with delayed branches in binary code can involve tricky case analyses, e.g., if there is a branch instruction in a delay slot. Correctness of a translation is of utmost importance. This paper presents a disciplined method for deriving such case analyses. The method identifies problematic cases, shows the translations for the non-problematic cases, and gives confidence that all cases are considered. The method supports such common architectures as SPARC, MIPS, and PA-RISC.
