I have tried to modify i386.c to make
ix86_force_to_memory&ix86_free_from_memory to generate frame related insn.That
causes another problem.Seems the only way to go is have a look at jump2.

The another problem:
ARGS_SIZE 12   .cfa_offset 12
push xxx       .cfa_offset 16
...
ARGS_SIZE 0    .cfa_offset 4

see?There is an orphan 4!
