     <li>Introduce pinsyscalls(2): The kernel and <a
           href="https://man.openbsd.org/ld.so.1">ld.so(1)</a> register the
           precise entry location of every system call used by a program, as
           described in the new ELF section .openbsd.syscalls inside ld.so and
           libc.so. ld.so uses the new syscall <a
           href="https://man.openbsd.org/pinsyscalls.2">pinsyscalls(2)</a> to
           tell the kernel the precise entry location of system calls in
           libc.so.<br>
         Attempting to use a different system call entry instruction to
           perform a non-corresponding system call operation will fail and the
           process will be terminated with signal SIGABRT.
     <li>Removed support for <a
           href="https://man.openbsd.org/syscall.2">syscall(2)</a>, the
           "indirection system call," a dangerous alternative entry point for all
           system calls.<br>
         Together with <a
           href="https://man.openbsd.org/pinsyscalls.2">pinsyscalls(2)</a> this
           change makes it ipmpossible to perform system call through any other
           way than the libc system cann wrapper functions.<br<
         Users of syscall(2), such as Perl and the Go programming
           languange were converted to use the libc functions.
