| 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. */ |
