* config/m68hc11/m68hc11.c (m68hc11_gen_movhi): Use 2,-sp to push
the stack register. (expand_prologue): Don't make an interrupt or a trap handler a far symbol. (m68hc11_initial_elimination_offset): Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@79058 138bc75d-0d04-0410-961f-82ee72b054a4
