A call to @code{exec}. This is currently only available for HP-UX
and @sc{gnu}/Linux.

+@item syscall
+@itemx syscall @r{[}@var{name} @r{|} @var{number}@r{]} @r{...}
+@cindex break on a system call.
+A call to or return from a @code{syscall}. If no argument is specified,
+then it catches a call to or return from any system call.
+
+@var{name} can be any valid system call name in the system. You can
+use the @value{GDBN} command-line completion facilities to list the
+available choices. @xref{Completion,, Command Completion}, for
+details on how to do this.
+
+You may also specify the system call numerically. This may be useful
+if @value{GDBN} does not fully support your system's list of system
+calls.
+
+The example below illustrates how this command works if you don't provide
+arguments to it:
+
+@smallexample
+(@value{GDBP}) catch syscall
+Catchpoint 1 (syscall)
+(@value{GDBP}) r
+Starting program: /tmp/catch-syscall
+
+Catchpoint 1 (call to syscall 'close'), 0xffffe424 in __kernel_vsyscall ()
+(@value{GDBP}) c
+Continuing.
+
+Catchpoint 1 (returned from syscall 'close'), 0xffffe424 in __kernel_vsyscall ()
+(@value{GDBP})
+@end smallexample
+
+Here is an example of catching a system call by name:
+
+@smallexample
+(@value{GDBP}) catch syscall chroot
+Catchpoint 1 (syscall(s) 'chroot')
+(@value{GDBP}) r
+Starting program: /tmp/catch-syscall
+
+Catchpoint 1 (call to syscall 'chroot'), 0xffffe424 in __kernel_vsyscall ()
+(@value{GDBP}) c
+Continuing.
+
+Catchpoint 1 (returned from syscall 'chroot'), 0xffffe424 in __kernel_vsyscall ()
+(@value{GDBP})
+@end smallexample
+
+And last but not least, an example of specifying a system call
+numerically:
+
+@smallexample
+(@value{GDBP}) catch syscall 252
+Catchpoint 1 (syscall(s) 'exit_group')
+(@value{GDBP}) r
+Starting program: /tmp/catch-syscall
+
+Catchpoint 1 (call to syscall 'exit_group'), 0xffffe424 in __kernel_vsyscall ()
+(@value{GDBP}) c
+Continuing.
+
+Program exited normally.
+(@value{GDBP})
+@end smallexample
+
+If you configure @value{GDBN} using the @samp{--without-expat} option,
+it will not be able to display syscall names. Also, if your
+architecture does not have an XML file describing its system calls,
+you will not be able to see the syscall names. In either case, you
+will see a warning like this:
+
+@smallexample
+(@value{GDBP}) catch syscall
+warning: Could not open "syscalls/i386-linux.xml"
+warning: Could not load the syscall XML file 'syscalls/i386-linux.xml'.
+GDB will not be able to display syscall names.
+Catchpoint 1 (syscall)
+(@value{GDBP})
+@end smallexample
+
+Of course, the file name will change depending on your architecture and system.
+
+Still using the example above, you can also try to catch a syscall by its
+number. In this case, you would see something like:
+
+@smallexample
+(@value{GDBP}) catch syscall 252
+Catchpoint 1 (syscall(s) 252)
+@end smallexample
+
+Again, in this case @value{GDBN} would not be able to display syscall's names.
+
