compare-sections: New -r option.
When connecting to a remote system, we use the compare-sections command to verify that the box is running the code that we think it is running. Since the system is up and running and *NOT* 'freshly downloaded without yet executing anything', read-write sections, of course, differ from what they were in the executable file. Comparing read-write sections takes time and more importantly the MIS-MATCHED output is confusing to some users. The compare-sections command compares all loadable sections including read-write sections. This patch gives the user the option to compare just the loadable read-only sections. gdb/ 2014-05-01 David Taylor <dtaylor@emc.com> * remote.c (compare_sections_command): Add -r option to compare all loadable read-only sections. gdb/doc/ 2014-05-01 David Taylor <dtaylor@emc.com> * gdb.texinfo (compare-sections): Document the new -r (read-only) option.

Compare the data of a loadable section @var{section-name} in the
executable file of the program being debugged with the same section in
the remote machine's memory, and report any mismatches. With no
-arguments, compares all loadable sections. This command's
+arguments, compares all loadable sections. With an argument of
+@code{-r}, compares all loadable read-only sections. This command's
availability depends on the target's support for the @code{"qCRC"}
remote request.
