invalid, as well as real registers.

and floating-point registers. Use fp_register_arg_p to determine
if float_argreg should be aligned.

sh_store_return_value().
* sh-tdep.c (sh_store_return_value): New function. Store the

* sh-tdep.c (sh_skip_prologue): Before looking at the actual
instructions, try to see if the symbol table can be of help, by
calling after_prologue(). If this doesn't work, call

more instruction pattern matching for pushing of arguments, and
manipulation of r14.
(after_prologue): New function. Use symbol table info to determine
