/* This file contains the main Perl opcode execution loop. It just |

|
|
* function to return a pointer to the next op to be executed, or null if |

|
|
* it's the end of the sub or program or whatever. |

|
|
* There is a similar loop in dump.c, Perl_runops_debug(), which does |
| 17 |
|
|

| 18 |
|
|
* loop. |
