* sh-tdep.h (struct gdbarch_tdep): New member FLOAT_ARGLAST_REG.
* sh-tdep.c (sh_gdbarch_init): For sh2e, sh3e, and sh4, set
FLOAT_ARG0_REGNUM and FLOAT_ARGLAST_REGNUM, to be used for
argument passing.
(sh_push_dummy_call_fpu, sh_push_dummy_call_nofpu): New
functions, replace sh_push_dummy_call.
(sh_gdbarch_init): Set push_dummy_call to one of new methods.
