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 file is part of the GDB testsuite. It tests reverse stepping.
|
|
#
|
|
# reverse-next over a function call sets a step-resume breakpoint at
|
|
# callee's entry point, runs to it, and then does an extra single-step
|
|
# to get at the callee's caller. Test that a user breakpoint set at
|
|
# the same location as the step-resume breakpoint isn't ignored.
|
|
#
|
|
# The test sets a breakpoint with the command break *callee to set a
|
|
# breakpoint on the first instruction of the function. The issue is on
|
|
# PowerPC it uses Global Entry Points (GEP) and Local Entry Points (LEP).
|
|
# The GEP is the first instruction in the function. It sets up register
|
|
# r2 and then reaches the LEP.
|
|
#
|
|
# <callee>:
|
|
# lis r2,4098 <- GEP
|
|
# addi r2,r2,32512
|
|
# mflr r0 <- LEP
|
|
# std r0,16(r1)
|
|
|
|
#
|
|
# The command break *callee sets the breakpoint on the GEP. Calling
|
|
# the function with callee() will enter the function via the LEP. So,
|
|
# this test needs to use a function pointer to call callee() so the
|
|
# function will be entered via the GEP to work as designed on PowerPC in
|
|
# addition to non-PowerPC systems. On non-PowerPC systems, the GEP and LEP
|
|
# are the same.
