840 /* Find and optionally add an entry in the change_sections list.
842 We need to be careful in how we match section names because of the support
843 for wildcard characters. For example suppose that the user has invoked
846 --set-section-flags .debug_*=debug
847 --set-section-flags .debug_str=readonly,debug
848 --change-section-address .debug_*ranges=0x1000
850 With the idea that all debug sections will receive the DEBUG flag, the
851 .debug_str section will also receive the READONLY flag and the
852 .debug_ranges and .debug_aranges sections will have their address set to
853 0x1000. (This may not make much sense, but it is just an example).
855 When adding the section name patterns to the section list we need to make
856 sure that previous entries do not match with the new entry, unless the
857 match is exact. (In which case we assume that the user is overriding
858 the previous entry with the new context).
860 When matching real section names to the section list we make use of the
861 wildcard characters, but we must do so in context. Eg if we are setting
862 section addresses then we match for .debug_ranges but not for .debug_info.
864 Finally, if ADD is false and we do find a match, we mark the section list
