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.

# Test GDB can cope with two libraries loaded with overlapping VMA ranges.
|
|
# Prelink libraries first so they can be loaded and their native address.
|
|
# In such case `struct linkmap'.l_addr will be zero. Provide different
|
|
# unprelinked library files on the disk which have zero-based VMAs. These
|
|
# different files should have their .dynamic section at a different offset in
|
|
# page size so that we get for
|
|
# warning: .dynamic section for "..." is not at the expected address
|
|
# the reason
|
|
# (wrong library or version mismatch?)
|
|
# and not:
|
|
# difference appears to be caused by prelink, adjusting expectations
|
|
# In such case both disk libraries will be loaded at VMAs starting at zero.
