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 test sets up a call stack that looks like this:
|
|
|
|
#11 #10 #9 #8 #7 #6 #5 #4 #3 #2 #1 #0
|
|
main -> aaa -> bbb -> ccc -> ddd -> eee -> fff -> ggg -> hhh -> iii -> jjj -> kkk
|
|
\_______________________/ \________/ \______________________/ \________/
|
|
Inline sequence #1 Normal Inline sequence #2 Normal
|
|
|
|
We use the 'start' command to move into main, after that we 'step'
|
|
through each function until we are in kkk. We then use the 'up' command
|
|
to look back at each from to main.
|
|
|
|
The test checks that we can handle and step through sequences of more
|
|
than one inline frame (so 'main .... ccc', and 'fff .... iii'), and also
|
|
that we can move around in a stack that contains more than one disjoint
|
|
sequence of inline frames.
|
|
|
|
The order of the functions in this file is deliberately mixed up so that
|
|
the line numbers are not "all ascending" or "all descending" in the line
|
|
table. */
