847 | /* Find and optionally add an entry in the change_sections list. |
848 | ||
849 | We need to be careful in how we match section names because of the support | |
850 | for wildcard characters. For example suppose that the user has invoked | |
851 | objcopy like this: | |
3aade688 | 852 | |
2e62b721 NC |
853 | --set-section-flags .debug_*=debug |
854 | --set-section-flags .debug_str=readonly,debug | |
855 | --change-section-address .debug_*ranges=0x1000 | |
856 | ||
857 | With the idea that all debug sections will receive the DEBUG flag, the | |
858 | .debug_str section will also receive the READONLY flag and the | |
859 | .debug_ranges and .debug_aranges sections will have their address set to | |
860 | 0x1000. (This may not make much sense, but it is just an example). | |
861 | ||
862 | When adding the section name patterns to the section list we need to make | |
863 | sure that previous entries do not match with the new entry, unless the | |
864 | match is exact. (In which case we assume that the user is overriding | |
865 | the previous entry with the new context). | |
866 | ||
867 | When matching real section names to the section list we make use of the | |
868 | wildcard characters, but we must do so in context. Eg if we are setting | |
869 | section addresses then we match for .debug_ranges but not for .debug_info. | |
870 | ||
871 | Finally, if ADD is false and we do find a match, we mark the section list | |
872 | entry as used. */ | |
