NC		 882/* Find and optionally add an entry in the change_sections list.
883
884 We need to be careful in how we match section names because of the support
885 for wildcard characters. For example suppose that the user has invoked
886 objcopy like this:
3aade688 887
2e62b721
NC		 888 --set-section-flags .debug_*=debug
889 --set-section-flags .debug_str=readonly,debug
890 --change-section-address .debug_*ranges=0x1000
891
892 With the idea that all debug sections will receive the DEBUG flag, the
893 .debug_str section will also receive the READONLY flag and the
894 .debug_ranges and .debug_aranges sections will have their address set to
895 0x1000. (This may not make much sense, but it is just an example).
896
897 When adding the section name patterns to the section list we need to make
898 sure that previous entries do not match with the new entry, unless the
899 match is exact. (In which case we assume that the user is overriding
900 the previous entry with the new context).
901
902 When matching real section names to the section list we make use of the
903 wildcard characters, but we must do so in context. Eg if we are setting
904 section addresses then we match for .debug_ranges but not for .debug_info.
905
906 Finally, if ADD is false and we do find a match, we mark the section list
907 entry as used. */

3483 One part is straight forward - if the output archive is in a different

3485 should be adjusted to the new location. But if any transformation
3486 options are active (eg strip, rename, add, etc) then the implication is
3487 that these should be applied to the files pointed to by the archive.
3488 But since objcopy is not destructive, this means that new files must be
3489 created, and there is no guidance for the names of the new files. (Plus
3490 this conflicts with one of the goals of thin libraries - only taking up
3491 a minimal amount of space in the file system).
