I mean, it's more or less random whether switching to and from the
function's section ends up inside the new .machine and
.machinemode directives (if the section needs to be switched for
this function) or outside (if the assembler code had already
switched to the correct section earlier).  I assume that .machine
and .machinemode have no effect on the section switching, but I'm
not completely sure (alignment?).

(@Andreas + Uli: Do you know of any effect this would have on
s390?)
