6622 | 10) The PSR.bn bit is only accessed when one of GR16-31 is specified in the | |

6625 | registers are only read if PR[qp] is true. Since the state of PR[qp] | |
6626 | cannot statically be determined, all source registers are marked used. | |
6627 | 12) This insn only reads the specified predicate register when that | |
6628 | register is the PR[qp]. | |
