This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

# Test to reproduce the crash described in PR 26813.
|
|
#
|
|
# When reading a list in any table in the .debug_rnglists section, GDB would
|
|
# read the header at offset 0 in the section (the header of the first table).
|
|
# When the index of the list we read was greater than the number of lists of
|
|
# the first table, GDB would erroneously report that the index is invalid.
|
|
#
|
|
# So this test creates a .debug_rnglists section with two tables. The second
|
|
# table has more lists than the first one and we try to read a high index in
|
|
# the second table.
