875 | /* Find and optionally add an entry in the change_sections list. |
876 | ||
877 | We need to be careful in how we match section names because of the support | |
878 | for wildcard characters. For example suppose that the user has invoked | |
879 | objcopy like this: | |
3aade688 | 880 | |
2e62b721 NC |
881 | --set-section-flags .debug_*=debug |
882 | --set-section-flags .debug_str=readonly,debug | |
883 | --change-section-address .debug_*ranges=0x1000 | |
884 | ||
885 | With the idea that all debug sections will receive the DEBUG flag, the | |
886 | .debug_str section will also receive the READONLY flag and the | |
887 | .debug_ranges and .debug_aranges sections will have their address set to | |
888 | 0x1000. (This may not make much sense, but it is just an example). | |
889 | ||
890 | When adding the section name patterns to the section list we need to make | |
891 | sure that previous entries do not match with the new entry, unless the | |
892 | match is exact. (In which case we assume that the user is overriding | |
893 | the previous entry with the new context). | |
894 | ||
895 | When matching real section names to the section list we make use of the | |
896 | wildcard characters, but we must do so in context. Eg if we are setting | |
897 | section addresses then we match for .debug_ranges but not for .debug_info. | |
898 | ||
899 | Finally, if ADD is false and we do find a match, we mark the section list | |
900 | entry as used. */ | |

3425 | One part is straight forward - if the output archive is in a different | |
3426 | directory from the input archive then any relative paths in the library | |
3427 | should be adjusted to the new location. But if any transformation | |
3428 | options are active (eg strip, rename, add, etc) then the implication is | |
3429 | that these should be applied to the files pointed to by the archive. | |
3430 | But since objcopy is not destructive, this means that new files must be | |
3431 | created, and there is no guidance for the names of the new files. (Plus | |
3432 | this conflicts with one of the goals of thin libraries - only taking up | |
3433 | a minimal amount of space in the file system). | |
