15254 %ymm registers not restored after signal handler
15367 x86 getfpregs() summons corrupting %xmm ghosts
15333 want x86 /proc xregs support (libc_db, libproc, mdb, etc.)
15336 want libc functions for extended ucontext_t
15334 want ps_lwphandle-specific reg routines
15328 FPU_CW_INIT mistreats reserved bit
15335 i86pc fpu_subr.c isn't really platform-specific
15332 setcontext(2) isn't actually noreturn
15331 need <sys/stdalign.h>

  .SH DESCRIPTION
- .LP
  Every program that links \fBlibthread_db\fR or \fBlibrtld_db\fR must provide a
  set of process control primitives that allow \fBlibthread_db\fR and
  \fBlibrtld_db\fR to access memory and registers in the target process, to start
  and to stop the target process, and to look up symbols in the target process.
  See \fBlibc_db\fR(3LIB). For information on \fBlibrtld_db\fR, refer to the
