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 the case where we have so many completions that we require the
|
|
# completions hash table within GDB to grow. Make sure that afte the
|
|
# hash table has grown we try to add duplicate entries into the
|
|
# hash. This checks that GDB doesn't corrupt the hash table when
|
|
# resizing it.
|
|
#
|
|
# In this case we create a test with more functions than the default
|
|
# number of entires in the completion hash table (which is 200), then
|
|
# complete on all function names.
|
|
#
|
|
# GDB will add all the function names from the DWARF, and then from
|
|
# the ELF symbol table, this ensures that we should have duplicates
|
|
# added after resizing the table.
