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