While stepping through gdb.reverse/time-reverse.exp I realized that we're
recording the instructions for resolving the PLT entries for functions time
and syscall, while that's not really the focus of the test-case.
Limit the scope of the test, by calling the functions once before starting
to record.
Also call "info record" after recording to make it clear how many
instructions were recorded.
On x86_64-linux, before this patch (but with info record added), we have:
...
$ grep "Log contains" gdb.log
Log contains 750 instructions.
Log contains 1218 instructions.
...
and with this patch we have:
...
$ grep "Log contains" gdb.log
Log contains 24 instructions.
Log contains 19 instructions.
...
Tested on x86_64-linux.

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.

Instead of only testing this on systems that have a SYS_time syscall,
test it everywhere using the time(2) C function, and in addition, run
the tests again using the SYS_time syscall.
The C variant ensures that if some platform uses some syscall we are
not aware of yet, we'll still exercise it, and likely fail, at which
point we should teach GDB about the syscall.
The explicit syscall variant is useful on platforms where the C
function does not call a syscall at all by default, e.g., on some
systems the C time function wraps an implementation provided by the
vDSO.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.

This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...

Update copyright year range in copyright header of all GDB files.

gdb/ChangeLog:
Update copyright year range in all GDB files.
|
|
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
