| 20 | /* 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. */ |
