* genflags.c (gen_macro): Delete.
(gen_proto): Don't create GEN.*CALL.* macros.
* gensupport.h (get_file_location): Declare.
* gensupport.c (rtx_locs): New variable.
(read_md_rtx): Record rtx locations.
(get_file_location): New function.
* target-insns.def (call, call_pop, call_value, call_value_pop)
(sibcall, sibcall_value): New patterns.
* gentarget-def.c (parse_argument): New function.
(def_target_insn): Use it. Handle optional operands. Raise an
error if an .md pattern has the wrong number of operands for the
pattern name. Remove the names of unused operands from the prototype.
* builtins.c (expand_builtin_apply): Use targetm functions
instead of HAVE_call_value and GEN_CALL_VALUE.

of GEN_CALL.
