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.

# The purpose of this testcase is to verify that, when using a breakpoint
|
|
# location of the form "*<EXPR>" (Eg: "*main"), GDB is able to start
|
|
# the program and stop at the correct location. With programs built
|
|
# as PIE, this means that GDB needs to re-evaluate the location once
|
|
# the program as started, since PIE ensures that the address of all
|
|
# symbols have changed after load.
|
|
#
|
|
# PIE is not always supported by the target system, so instead of
|
|
# creating a testcase building executables with PIE, this testcase
|
|
# takes a slightly different approach. It builds a first program,
|
|
# breaks on *main, and then runs to that breakpoint. It then builds
|
|
# a second program, different from the first one, and loads that
|
|
# executable within the same GDB session. Similarly to the PIE case,
|
|
# the address of main should be different, and therefore GDB should
|
|
# recalculate it. We verify that by checking that running to that
|
|
# breakpoint still works, and that we land at the first instruction
|
|
# of that function in both cases.
