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.
|

Add a new script gdb/syscalls/update-linux-from-src.sh, that can be used to
generate *-linux.xml.in files from linux kernel sources, like so:
...
$ ./update-linux-from-src.sh ~/upstream/linux-stable.git
Skipping aarch64-linux.xml.in, no syscall.tbl
Generating amd64-linux.xml.in
Skipping arm-linux.xml.in, use arm-linux.py instead
Skipping bfin-linux.xml.in, no longer supported
Generating i386-linux.xml.in
Generating mips-n32-linux.xml.in
Generating mips-n64-linux.xml.in
Generating mips-o32-linux.xml.in
Generating ppc64-linux.xml.in
Generating ppc-linux.xml.in
Generating s390-linux.xml.in
Generating s390x-linux.xml.in
Generating sparc64-linux.xml.in
Generating sparc-linux.xml.in
...
Update *-linux.xml.in and *-linux.xml using linux kernel tag v5.18-rc6.

- Add a script syscalls/gen-header.py, based on syscalls/arm-linux.py.
- Add a script syscalls/update-linux.sh (alongside update-freebsd.sh and
update-netbsd.sh).
- Use syscalls/update-linux.sh to update syscalls/{amd64,i386}-linux.xml.in.
- Regenerate syscalls/{amd64,i386}-linux.xml using syscalls/Makefile.
In gdb/syscalls/i386-linux.xml.in, updating has the following notable effect:
...
- <syscall name="madvise1" number="220"/>
- <syscall name="getdents64" number="221"/>
- <syscall name="fcntl64" number="222"/>
+ <syscall name="getdents64" number="220"/>
+ <syscall name="fcntl64" number="221"/>
...
I've verified in ./arch/x86/entry/syscalls/syscall_32.tbl that the numbers are
correct.
Tested on x86_64-linux.

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.

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.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

Implement support to add catchpoints for a group of related syscalls
using the syntax:
(gdb) catch syscall group:<group>
or
(gdb) catch syscall g:<group>
Several groups are predefined in the xml files for all architectures
supported by GDB over Linux. They are based on the groups defined by
strace.
