gdb: TUI Overview

 
 25.1 TUI Overview
 =================
 
 In TUI mode, GDB can display several text windows:
 
 _command_
      This window is the GDB command window with the GDB prompt and the
      GDB output.  The GDB input is still managed using readline.
 
 _source_
      The source window shows the source file of the program.  The
      current line and active breakpoints are displayed in this window.
 
 _assembly_
      The assembly window shows the disassembly output of the program.
 
 _register_
      This window shows the processor registers.  Registers are
      highlighted when their values change.
 
    The source and assembly windows show the current program position by
 highlighting the current line and marking it with a '>' marker.
 Breakpoints are indicated with two markers.  The first marker indicates
 the breakpoint type:
 
 'B'
      Breakpoint which was hit at least once.
 
 'b'
      Breakpoint which was never hit.
 
 'H'
      Hardware breakpoint which was hit at least once.
 
 'h'
      Hardware breakpoint which was never hit.
 
    The second marker indicates whether the breakpoint is enabled or not:
 
 '+'
      Breakpoint is enabled.
 
 '-'
      Breakpoint is disabled.
 
    The source, assembly and register windows are updated when the
 current thread changes, when the frame changes, or when the program
 counter changes.
 
    These windows are not all visible at the same time.  The command
 window is always visible.  The others can be arranged in several
 layouts:
 
    * source only,
 
    * assembly only,
 
    * source and assembly,
 
    * source and registers, or
 
    * assembly and registers.
 
    A status line above the command window shows the following
 information:
 
 _target_
      Indicates the current GDB target.  (Specifying a Debugging
      Target Targets.).
 
 _process_
      Gives the current process or thread number.  When no process is
      being debugged, this field is set to 'No process'.
 
 _function_
      Gives the current function name for the selected frame.  The name
      is demangled if demangling is turned on (Print Settings).
      When there is no symbol corresponding to the current program
      counter, the string '??' is displayed.
 
 _line_
      Indicates the current line number for the selected frame.  When the
      current line number is not known, the string '??' is displayed.
 
 _pc_
      Indicates the current program counter address.
