| 401 | * Each flag is now a bit offset, starting at zero. The macros |

|
|
| 403 | * structure. |
|
|
| 404 | * |
|
|
| 405 | * Hopefully, since these offsets are integer constants set at run time, |

|
|
| 407 | * old system was. |
|
|
| 408 | * |
|
|
| 409 | * Flags now have FLAG as the prefix. This to be clearer, and also |
|
|
| 410 | * to make sure F_ names are not still being used anyplace. |
|
|
| 411 | * |
|
|
| 412 | * The macros below assume that the flag size for each element is 32 |
|
|
| 413 | * bits. IF it is smaller, bad things will happen. See structs.h |
|
|
| 414 | * for more info. |
|

|
|
| 416 | * All functions should use the macros below. In process of converting |
|
|
| 417 | * to the new system, I find several files that did not use the previous |
|
|
| 418 | * macros. |

401 | * If any FLAG's are added or changed, make sure the flag_names structure in |
| 421 | * common/loader.l is updated. |
