840 | /* Find and optionally add an entry in the change_sections list. |
841 | ||
842 | We need to be careful in how we match section names because of the support | |
843 | for wildcard characters. For example suppose that the user has invoked | |
844 | objcopy like this: | |
3aade688 | 845 | |
2e62b721 NC |
846 | --set-section-flags .debug_*=debug |
847 | --set-section-flags .debug_str=readonly,debug | |
848 | --change-section-address .debug_*ranges=0x1000 | |
849 | ||
850 | With the idea that all debug sections will receive the DEBUG flag, the | |
851 | .debug_str section will also receive the READONLY flag and the | |
852 | .debug_ranges and .debug_aranges sections will have their address set to | |
853 | 0x1000. (This may not make much sense, but it is just an example). | |
854 | ||
855 | When adding the section name patterns to the section list we need to make | |
856 | sure that previous entries do not match with the new entry, unless the | |
857 | match is exact. (In which case we assume that the user is overriding | |
858 | the previous entry with the new context). | |
859 | ||
860 | When matching real section names to the section list we make use of the | |
861 | wildcard characters, but we must do so in context. Eg if we are setting | |
862 | section addresses then we match for .debug_ranges but not for .debug_info. | |
863 | ||
864 | Finally, if ADD is false and we do find a match, we mark the section list | |
865 | entry as used. */ | |
