The compact-casesi was only designed for ARCv1 types of CPUs. Unfortunately, it was error prone leading to all kinds of runtime and compile time errors. Fixing it will nullify most of the advantages of using this format. Hence, I've remove it, leaving the standard implementation for all CPUS. The BI/BIH are two new instructions for ARCv2, and they should be friendly with the cache, but I couldn't prove that, hence they are guarded by an option. Please let me know if you want to have compact-casesi back in the compiler. Thanks, Claudiu
