/* Basic 80960 instruction formats.
 *
 * The 'COJ' instructions are actually COBR instructions with the 'b' in
 * the mnemonic replaced by a 'j';  they are ALWAYS "de-optimized" if necessary:
 * if the displacement will not fit in 13 bits, the assembler will replace them
 * with the corresponding compare and branch instructions.
 *
 * All of the 'MEMn' instructions are the same format; the 'n' in the name
 * indicates the default index scale factor (the size of the datum operated on).
 *
 * The FBRA formats are not actually an instruction format.  They are the
 * "convenience directives" for branching on floating-point comparisons,
 * each of which generates 2 instructions (a 'bno' and one other branch).
 *
 * The CALLJ format is not actually an instruction format.  It indicates that
 * the instruction generated (a CTRL-format 'call') should have its relocation
 * specially flagged for link-time replacement with a 'bal' or 'calls' if
 * appropriate.
