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. */
