This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

This script updates the list of years in the copyright notices in

most files maintained by the GDB project.
|
|
|
|
Usage: cd src/gdb && python copyright.py
|
|
|
|
Always review the output of this script before committing it!
|
|
A useful command to review the output is:
|
|
% filterdiff -x \*.c -x \*.cc -x \*.h -x \*.exp updates.diff
|
|
This removes the bulk of the changes which are most likely to be correct.
