2003-05-02 Elena Zannoni <ezannoni@redhat.com> * charset.c (GDB_DEFAULT_TARGET_CHARSET, GDB_DEFAULT_HOST_CHARSET): Move to earlier in the file. (host_charset_name, target_charset_name): New vars for use by set/show commands. (host_charset_enum, target_charset_enum): New enums for set/show commands. (set_charset_sfunc, set_host_charset_sfunc, set_target_charset_sfunc): New functions. (set_host_charset, set_target_charset): Make static. (list_charsets, set_host_charset_command, set_target_charset_command): Delete functions. (show_charset_command): Rewrite as.... (show_charset): Hook this up with the set/show command mechanism. (_initialize_charset): Change names of charsets to match the set/show enums. Use host_charset_name and target_charset_name. Use set/show mechanism for charset, host-charset, target-charset commands. Do not make 'show host-charset' and 'show target-charset' be aliases of 'show charset'. * charset.h (set_host_charset, set_target_charset): Don't export, they are not used outside the file. gdb/testsuite: 2003-05-01 Elena Zannoni <ezannoni@redhat.com> * gdb.base/charset.exp: Update based on new behavior of set/show charset commands. gdb/doc: 2003-05-02 Elena Zannoni <ezannoni@redhat.com> * gdb.texinfo (Character Sets): Update to reflect new behavior of set/show charsets commands.
