For example, FreeBSD 12 altered the layout of 'struct + kevent' used by the 'kevent' system call. As a result, FreeBSD 12 + kernels ship with both 'kevent' and 'freebsd11_kevent' system calls. + The 'freebsd11_kevent' system call is assigned an alias of 'kevent' + so that a system call catchpoint for the 'kevent' system call will + catch invocations of both the 'kevent' and 'freebsd11_kevent' + binaries. This ensures that 'kevent' system calls are caught for + binaries using either the old or new ABIs. + * New targets NXP S12Z s12z-*-elf |
