* dwarf2loc.c (dwarf_expr_frame_base): Use SYMBOL_OPS instead of SYMBOL_LOCATION_FUNCS (dwarf2_loclist_funcs, dwarf2_locexpr_funcs): Change type to "struct symbol_ops". * dwarf2loc.h (dwarf2_locexpr_funcs, dwarf2_loclist_funcs): Change type to "struct symbol_ops". * symtab.h (struct symbol_ops): Rename "struct location_funcs". (struct symbol): Replace ".aux_value.loc.funcs" and ".aux_value.loc.baton" with ".ops" and ".aux_value.ptr". (SYMBOL_OBJFILE): Delete macro. (SYMBOL_LOCATION_FUNCS): Delete macro. (SYMBOL_LOCATION_BATON): Update. * dwarf2read.c (dwarf2_symbol_mark_computed): Set SYMBOL_OPS intead of SYMBOL_LOCATION_FUNCS. * ax-gdb.c (gen_var_ref): Ditto. * printcmd.c (address_info): Ditto. * findvar.c (read_var_value): Ditto.
