The 'maintenance info sections' command currently takes a list of filters on the command line. It can also accept the magic string 'ALLOBJ' which acts more like a command line flag, telling the command to print information about all objfiles. The manual has this to say about the options and filters: ... In addition, 'maint info sections' provides the following command options (which may be arbitrarily combined): ... Implying (to me at least) that I can do this: (gdb) maint info sections ALLOBJ READONLY to list all the read-only sections from all currently loaded object files. Unfortunately, this doesn't work. The READONLY filter will work, but ALLOBJ will not be detected correctly. It would be fairly simple to fix the ALLOBJ detection. However, I dislike this mixing of command options (ALLOBJ) with command data (the filters, e.g. READONLY, etc). As this is a maintenance command, so not really intended for end users, I think we can be a little more aggressive in "fixing" the option parsing. So that's what I do in this commit. The ALLOBJ mechanism is replaced with a real command option (-all-objects). The rest of the command operates just as before. The example above would now become: (gdb) maint info sections -all-objects READONLY The manual has been updated, and I added a NEWS entry to document the change. gdb/ChangeLog: * NEWS: Mention changes to 'maint info sections'. * maint.c (match_substring): Return a bool, fix whitespace issue. (struct single_bfd_flag_info): New struct. (bfd_flag_info): New static global. (match_bfd_flags): Return a bool, use bfd_flag_info. (print_bfd_flags): Use bfd_flag_info. (maint_print_section_info): Delete trailing whitespace. (struct maint_info_sections_opts): New struct. (maint_info_sections_option_defs): New static global. (maint_info_sections_completer): New function. (maintenance_info_sections): Use option parsing mechanism. (_initialize_maint_cmds): Register command completer. gdb/doc/ChangeLog: * gdb.texinfo (Files): Update documentation for 'maint info sections'. gdb/testsuite/ChangeLog: * gdb.base/maint-info-sections.exp: Update expected output, and add additional tests. Again. |
