889 | /* Find and optionally add an entry in the change_sections list. |
890 | ||
891 | We need to be careful in how we match section names because of the support | |
892 | for wildcard characters. For example suppose that the user has invoked | |
893 | objcopy like this: | |
3aade688 | 894 | |
2e62b721 NC |
895 | --set-section-flags .debug_*=debug |
896 | --set-section-flags .debug_str=readonly,debug | |
897 | --change-section-address .debug_*ranges=0x1000 | |
898 | ||
899 | With the idea that all debug sections will receive the DEBUG flag, the | |
900 | .debug_str section will also receive the READONLY flag and the | |
901 | .debug_ranges and .debug_aranges sections will have their address set to | |
902 | 0x1000. (This may not make much sense, but it is just an example). | |
903 | ||
904 | When adding the section name patterns to the section list we need to make | |
905 | sure that previous entries do not match with the new entry, unless the | |
906 | match is exact. (In which case we assume that the user is overriding | |
907 | the previous entry with the new context). | |
908 | ||
909 | When matching real section names to the section list we make use of the | |
910 | wildcard characters, but we must do so in context. Eg if we are setting | |
911 | section addresses then we match for .debug_ranges but not for .debug_info. | |
912 | ||
913 | Finally, if ADD is false and we do find a match, we mark the section list | |
914 | entry as used. */ | |
