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 test is about restarting execution of a forked application when
|
|
# using gdb extended remote target.
|
|
#
|
|
# There are two issues that the test tries to expose in GDB:
|
|
#
|
|
# 1. GDB would throw an assertion upon reconnecting to a remote target
|
|
# if there was more than one inferior already active in GDB, and
|
|
#
|
|
# 2. GDB would not prune transient inferiors from the inferior list
|
|
# when reconnecting to a remote target. So, for example, an inferior
|
|
# created by GDB to track the child of a fork would usually be removed
|
|
# from the inferior list once the child exited. However, reconnecting
|
|
# to a remote target would result in the child inferior remaining in
|
|
# the inferior list.
|
|
|
|
# This test is only for extended remote targets.
