--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It also fails all over on powerpc-linux. Pretty much all targets just
do something like
/* Extra stack adjustment for exception handler return. */
if (crtl->calls_eh_return)
emit_insn (gen_addsi3 (stack_pointer_rtx, stack_pointer_rtx,
EH_RETURN_STACKADJ_RTX));
/* Now we can return. */
emit_jump_insn (gen_simple_return ());
A fix should be target-independent, or it should fix all targets.
