726 | /* Find and optionally add an entry in the change_sections list. |
727 | ||
728 | We need to be careful in how we match section names because of the support | |
729 | for wildcard characters. For example suppose that the user has invoked | |
730 | objcopy like this: | |
731 | ||
732 | --set-section-flags .debug_*=debug | |
733 | --set-section-flags .debug_str=readonly,debug | |
734 | --change-section-address .debug_*ranges=0x1000 | |
735 | ||
736 | With the idea that all debug sections will receive the DEBUG flag, the | |
737 | .debug_str section will also receive the READONLY flag and the | |
738 | .debug_ranges and .debug_aranges sections will have their address set to | |
739 | 0x1000. (This may not make much sense, but it is just an example). | |
740 | ||
741 | When adding the section name patterns to the section list we need to make | |
742 | sure that previous entries do not match with the new entry, unless the | |
743 | match is exact. (In which case we assume that the user is overriding | |
744 | the previous entry with the new context). | |
745 | ||
746 | When matching real section names to the section list we make use of the | |
747 | wildcard characters, but we must do so in context. Eg if we are setting | |
748 | section addresses then we match for .debug_ranges but not for .debug_info. | |
749 | ||
750 | Finally, if ADD is false and we do find a match, we mark the section list | |
751 | entry as used. */ | |
