From: Tom Tromey Date: Tue, 14 Jun 2011 18:44:40 +0000 (+0000) Subject: * jv-lang.c (jv_type_objfile_data_key, dynamics_objfile) X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86cc0029254e12b51a0882bd29d442b84e3861e1;p=binutils-gdb.git * jv-lang.c (jv_type_objfile_data_key, dynamics_objfile) (class_symtab): Remove. (jv_dynamics_progspace_key): New global. (jv_per_objfile_free): Reset program space data. Update assert. Don't clear globals. (get_dynamics_objfile): Use and set program space data. (get_java_class_symtab): Use get_dynamics_objfile. (add_class_symbol): Likewise. (java_link_class_type): Likewise. (java_object_type, jv_clear_object_type, set_java_object_type): Remove. (get_java_object_type): Update. Don't cache result. (is_object_type): Don't call set_java_object_type.
