Provide a new completion function for the argument of "info registers", "info all-registers", and the "lr" command in dbx mode. Without this patch the default symbol completer is used, which is more confusing than helpful. Also add a test for this new feature to "completion.exp": Determine the target's available set of registers/reggroups and compare this to the completion of "info registers ". For determining the available registers involve the new "maint print user-registers" command. gdb/ChangeLog: * completer.c: Include "target.h", "reggroups.h", and "user-regs.h". (reg_or_group_completer): New. * completer.h (reg_or_group_completer): Declare. * infcmd.c (_initialize_infcmd): Set reg_or_group_completer for the "info registers" and "info all-registers" commands and the dbx-mode "lr" command. gdb/testsuite/ChangeLog: * gdb.base/completion.exp: Add test for completion of "info registers ".
