gdb: Rework command completion on 'tui reg'.
We previously specified a few known register groups for the 'tui reg' command. Other register groups could be accessed, but only by using the 'tui reg next' command and cycling through all the groups. This commit removes the hard coded sub-commands of 'tui reg' and instead adds dynamic completion of sub-commands based on the architecturally defined register groups, giving immediate access to all available register groups. There is still the 'next' and 'prev' commands for cycling through the register groups if that's wanted. The new code maintains the ability to only enter partial names for register groups, which is something we got for free when using the standard sub-command mechanism. The register (and register group) completer has been changed to use get_current_arch rather than using the architecture of the currently selected frame. When the target is running, this is equivalent, however, when the target is not running, using get_current_arch will provide results from the default architecture. gdb/ChangeLog: * completer.c: Add arch-utils.h include. (enum reg_completer_targets): New enum. (reg_or_group_completer_1): New function containing old reg_or_group_completer, add and use new parameter to control what is completed on. Use get_current_arch rather than architecture of currently selected frame. (reg_or_group_completer): Call new reg_or_group_completer_1. (reggroup_completer): Call new reg_or_group_completer_1. * completer.h (reggroup_completer): Add declaration. * tui/tui-regs.c: Add 'completer.h' include. (tui_reg_next_command): Renamed to... (tui_reg_next): ...this. Adjust parameters and return rather than display new group. (tui_reg_prev_command): Renamed to... (tui_reg_prev): ...this. Adjust parameters and return rather than display new group. (tui_reg_float_command): Delete. (tui_reg_general_command): Delete. (tui_reg_system_command): Delete. (tui_reg_command): Rewrite to perform switching of register group. Add header comment. (tuireglist): Remove. (tui_reggroup_completer): New function. (_initialize_tui_regs): Remove 'tui reg' sub-commands, update creation of 'tui reg' command. * NEWS: Add comment about 'tui reg' changes. gdb/doc/ChangeLog: * gdb.texinfo (TUI Commands): Bring all 'tui reg' commands into a single table entry.
