* dwarf2-frame.c (dwarf2_frame_find_quirks): Use producer_is_realview.
* dwarf2read.c (load_full_comp_unit): Read DW_AT_producer.
(read_structure_type): For RealView, set TYPE_STUB on structures with
no byte size and no children.
(read_subroutine_type): Mark functions as prototyped by default.
* symtab.c (producer_is_realview): New function.
* symtab.h (expand_line_sal): Fix declaration formatting.
(producer_is_realview): Declare.
testsuite/
* gdb.base/callfuncs.exp (do_function_calls): Add XFAILs for RealView.
* gdb.base/ptype.exp (ptype_maybe_prototyped): Add overprototyped
argument. Handle "short" and "long".
(Top level): Pass overprototyped output for old_fptr and xptr.
