Rename target_ops.arch_setup to .post_create_inferior. In the Linux hook, continue calling the low arch setup, then also set ptrace flags. This corrects the possibility of running without flags, demonstrated by a new test that would fail to catch a fork before. gdb/gdbserver/ChangeLog: 2015-12-04 Josh Stone <jistone@redhat.com> * target.h (struct target_ops) <arch_setup>: Rename to ... (struct target_ops) <post_create_inferior>: ... this. (target_arch_setup): Rename to ... (target_post_create_inferior): ... this, calling post_create_inferior. * server.c (start_inferior): Update target_arch_setup calls to target_post_create_inferior. * linux-low.c (linux_low_ptrace_options): Forward declare. (linux_arch_setup): Update its comment for general use. (linux_post_create_inferior): New, run arch_setup and setup ptrace. (struct linux_target_ops): Use linux_post_create_inferior. * lynx-low.c (struct lynx_target_ops): Update arch_setup stub comment to post_create_inferior. * nto-low.c (struct nto_target_ops): Likewise. * spu-low.c (struct spu_target_ops): Likewise. * win32-low.c (struct win32_target_ops): Likewise. gdb/testsuite/ChangeLog: 2015-12-04 Josh Stone <jistone@redhat.com> * gdb.base/catch-fork-static.exp: New.
