/* The 'COJ' instructions are actually COBR instructions with the 'b' in
21
   the mnemonic replaced by a 'j';  they are ALWAYS "de-optimized" if
22
   necessary: if the displacement will not fit in 13 bits, the assembler will
23
   replace them with the corresponding compare and branch instructions.
24
 
25
   All of the 'MEMn' instructions are the same format; the 'n' in the name
26
   indicates the default index scale factor (the size of the datum operated on).
27
 
28
   The FBRA formats are not actually an instruction format.  They are the
29
   "convenience directives" for branching on floating-point comparisons,
30
   each of which generates 2 instructions (a 'bno' and one other branch).
31
 
32
   The CALLJ format is not actually an instruction format.  It indicates that
33
   the instruction generated (a CTRL-format 'call') should have its relocation
34
   specially flagged for link-time replacement with a 'bal' or 'calls' if
35
   appropriate.  */
