Eli mentioned [1] that given that we use US English spelling in our documentation, we should use "behavior" instead of "behaviour". In wikipedia-common-misspellings.txt there's a rule: ... behavour->behavior, behaviour ... which leaves this as a choice. Add an overriding rule to hardcode the choice to common-misspellings.txt: ... behavour->behavior ... and add a rule to rewrite behaviour into behavior: ... behaviour->behavior ... and re-run spellcheck.sh on gdb*. Tested on x86_64-linux. [1] https://sourceware.org/pipermail/gdb-patches/2024-November/213371.html

# In this test we're looking at how gdb handles backtraces and
|
|
# investigating the stack depth when confronted with an "invalid" stack,
|
|
# that is a stack where the first few frames are normal, and then there's a
|
|
# frame where the stack in unreadable.
|
|
#
|
|
# One interesting bug that has been observed is that gdb will sometime
|
|
# exhibit different behavior the first time a stack command is run
|
|
# compared to the second (and later) times a command is run. This is
|
|
# because the first time a command is run gdb actually tries to figure out
|
|
# the answer, while the second (and later) times gdb relies on the answer
|
|
# cached from the first time. As a result in this test each command is
|
|
# run twice, and we restart gdb before testing each different command to
|
|
# ensure that nothing is being cached.
