Instead of having the gdb.RegisterDescriptorIterator creating new gdb.RegisterDescriptor objects for each regnum, instead cache gdb.RegisterDescriptor objects on the gdbarch object and reuse these. This means that for every gdbarch/regnum pair there is a single unique gdb.RegisterDescriptor, this feels like a neater implementation than the existing one. It is possible for a user to see (in Python code) that the descriptors are now identical, but as the descriptors are read-only this should make no real difference. There should be no other user visible changes. gdb/ChangeLog: * python/py-registers.c (gdbpy_register_object_data): New static global. (gdbpy_register_object_data_init): New function. (gdbpy_new_register_descriptor): Renamed to... (gdbpy_get_register_descriptor): ...this, and update to reuse existing register descriptors where possible. (gdbpy_register_descriptor_iter_next): Update. (gdbpy_initialize_registers): Register new gdbarch data. gdb/testsuite/ChangeLog: * gdb.python/py-arch-reg-names.exp: Additional tests.
