| 68 | relative to segment (here it is one PE section), which in |
| 69 | turn specifies its start as a VA relative to "image base". |

sewardj | 54c45db | 2012-07-13 12:58:55 +0000 | [diff] [blame] | 74 | The original/preferred image base is set in the PE header, |
| 75 | but it can change as long as the file contains relocation |
| 76 | data. So everything is biased using the current image base, |
| 77 | which is the base AVMA passed by Wine. |
