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.

# This script intends to facilitate spell checking of source/doc files.
|
|
# It:
|
|
# - transforms the files into a list of lowercase words
|
|
# - prefixes each word with the frequency
|
|
# - filters out words within a frequency range
|
|
# - sorts the words, longest first
|
|
#
|
|
# If '-c' is passed as option, it operates on the C comments only, rather than
|
|
# on the entire file.
|
|
#
|
|
# For:
|
|
# ...
|
|
# $ files=$(find gdb -type f -name "*.c" -o -name "*.h")
|
|
# $ ./gdb/contrib/words.sh -c $files
|
|
# ...
|
|
# it generates a list of ~15000 words prefixed with frequency.
|
|
#
|
|
# This could be used to generate a dictionary that is kept as part of the
|
|
# sources, against which new code can be checked, generating a warning or
|
|
# error. The hope is that misspellings would trigger this frequently, and rare
|
|
# words rarely, otherwise the burden of updating the dictionary would be too
|
|
# much.
|
|
#
|
|
# And for:
|
|
# ...
|
|
# $ files=$(find gdb -type f -name "*.c" -o -name "*.h")
|
|
# $ ./gdb/contrib/words.sh -c -f 1 $files
|
|
# ...
|
|
# it generates a list of ~5000 words with frequency 1.
|
|
#
|
|
# This can be used to scan for misspellings manually.
