* config/bfin/bfin-protos.h (bfin_longcall_p): Declare.
* config/bfin/predicates.md (symbol_ref_operand): New.
(call_insn_operand): Delete. All callers changed to use
register_no_elim_operand.
* config/bfin/bfin.c (init_cumulative_args): Initialize the new
call_cookie field.
(function_arg): Use it to generate the call's operand 2.
(bfin_longcall_p): New function.
(bfin_expand_call): Extra arg "cookie". All callers and declaration
changed. Emit extra USE in the pattern. Use bfin_longcall_p to
determine if the address needs to be in a REG.
(bfin_handle_longcall_attribute): New function.
(bfin_attribute_table): Add "longcall" and "shortcall".
* config/bfin/bfin.h (CALL_NORMAL, CALL_LONG, CALL_SHORT): New macros.

* config/bfin/bfin.md (call, call_value, sibcall, sibcall_value): Add
extra USE to the pattern.
(call_symbol, sibcall_symbol, call_value_symbol, sibcall_value_symbol):
New patterns, split off call_insn, sibcall_insn, call_value_insn and
sibcall_value_insn; now the new patterns handle direct calls and the
old ones indirect calls.
* doc/extend.texi: Mention Blackfin in longcall/shortcall docs.
