Comment (by Chris Johns):

 There ae a number of version of `eieio` in RTEMS. The implementation in
 `io.h` is:
 {{{
 __asm__ __volatile__ ("eieio");
 }}}
 and the FreeBSD is:
 {{{
  __asm __volatile ("eieio" : : : "memory");
 }}}
 I am not sure about the specifics of needing the memory constrain but I
 wonder if it is something we should do? I do not know the PowerPC well
 enough to know the effect of having `memory` as a constraint.
