| 29 | <h4>DESCRIPTION</h4> | |
| 30 | <ul> | |
| 31 | Prints cpu registers. | |
| 32 | <p> | |
| 33 | By default, only the registers of the cpu specified by <a | |
| 34 | href="cmd_pselect.html">pselect</a> are printed. | |
| 35 | The <a href="flag_cpu.html">-cpu</a> flag may be used to override this. | |
| 36 | <p> | |
| 37 | The -w ,-g, -f, -df, -pr, -asr, -hpr, and -trap flags select which | |
| 38 | registers are printed. If none of these are given, pregs prints the | |
| 39 | windowed and global registers plus the pc, npc, tt, tl, gl, cwp, | |
| 40 | pstate, and hpstate registers. | |
| 41 | <p> | |
| 42 | The -w ,-g, -f, -df, -asr, -pr, -hpr, and -trap flags may be used in | |
| 43 | any combination. The registers they output are as follows: | |

| 83 | </table><br> | |
| 84 | <p> | |
| 85 | By default, the current cwp register, global level, and trap level are | |
| 86 | used to access windowed registers, global registers, and trap | |
| 87 | registers, respectively. | |
