732 We need to be careful in how we match section names because of the support
733 for wildcard characters. For example suppose that the user has invoked
734 objcopy like this:
3aade688 735
2e62b721
NC		 736 --set-section-flags .debug_*=debug
737 --set-section-flags .debug_str=readonly,debug
738 --change-section-address .debug_*ranges=0x1000
739
740 With the idea that all debug sections will receive the DEBUG flag, the
741 .debug_str section will also receive the READONLY flag and the
742 .debug_ranges and .debug_aranges sections will have their address set to
743 0x1000. (This may not make much sense, but it is just an example).
744
745 When adding the section name patterns to the section list we need to make
746 sure that previous entries do not match with the new entry, unless the
747 match is exact. (In which case we assume that the user is overriding
748 the previous entry with the new context).
749
750 When matching real section names to the section list we make use of the
751 wildcard characters, but we must do so in context. Eg if we are setting
752 section addresses then we match for .debug_ranges but not for .debug_info.
753
754 Finally, if ADD is false and we do find a match, we mark the section list
755 entry as used. */
