SUSE-SU-2024:0899-1

This update for gdb fixes the following issues:

• Drop libdebuginfod1 BuildRequires/Recommends. The former isn't needed because there's a build requirement on libdebuginfod-devel already, which will pull the shared library. And the latter, because it's bogus since RPM auto generated dependency will take care of that requirement.

gdb was released in 13.2:

• This version of GDB includes the following changes and enhancements:

  • Support for the following new targets has been added in both GDB and GDBserver:

    * GNU/Linux/LoongArch (gdbserver) loongarch*-*-linux*
    * GNU/Linux/CSKY (gdbserver) csky*-*linux* 
    

  • The Windows native target now supports target async.

  • Floating-point support has now been added on LoongArch GNU/Linux.

  • New commands:

    * set print nibbles [on|off]
    * show print nibbles
    
    * This controls whether the 'print/t' command will display binary values in groups of four bits, known as 'nibbles'. The default is 'off'.
      Various styling-related commands. See the gdb/NEWS file for more details.
      Various maintenance commands. These are normally aimed at GDB experts or developers. See the gdb/NEWS file for more details. 
    

  • Python API improvements:

      * New Python API for instruction disassembly.
    
      * The new attribute 'locations' of gdb.Breakpoint returns a list of gdb.BreakpointLocation objects specifying the locations where the breakpoint is inserted into the debuggee.
      * New Python type gdb.BreakpointLocation.
      * New function gdb.format_address(ADDRESS, PROGSPACE, ARCHITECTURE) that formats ADDRESS as 'address '
      * New function gdb.current_language that returns the name of the current language. Unlike gdb.parameter('language'), this will never return 'auto'.
      * New function gdb.print_options that returns a dictionary of the prevailing print options, in the form accepted by gdb.Value.format_string.
      * New method gdb.Frame.language that returns the name of the frame's language.
      * gdb.Value.format_string now uses the format provided by 'print', if it is called during a 'print' or other similar operation.
      * gdb.Value.format_string now accepts the 'summary' keyword. This can be used to request a shorter representation of a value, the way that 'set print frame-arguments scalars' does.
      * The gdb.register_window_type method now restricts the set of acceptable window names. The first character of a window's name must start with a character in the set [a-zA-Z], every subsequent character of a window's name must be in the set [-_.a-zA-Z0-9]. 
    

  • GDB/MI changes:

     * MI version 1 is deprecated, and will be removed in GDB 14.
     * The async record stating the stopped reason 'breakpoint-hit' now contains an optional field locno. 
    

  • Miscellaneous improvements:

     * gdb now supports zstd compressed debug sections (ELFCOMPRESS_ZSTD) for ELF.
     * New convenience variable $_inferior_thread_count contains the number of live threads in the current inferior.
     * New convenience variables $_hit_bpnum and $_hit_locno, set to the breakpoint number and the breakpoint location number of the breakpoint last hit.
     * The 'info breakpoints' now displays enabled breakpoint locations of disabled breakpoints as in the 'y-' state.
     * The format of 'disassemble /r' and 'record instruction-history /r' has changed to match the layout of GNU objdump when disassembling.
    
     * A new format '/b' has been introduce to provide the old behavior of '/r'.
     * The TUI no longer styles the source and assembly code highlighted by the current position indicator by default. You can however re-enable styling using the new 'set style tui-current-position' command.
     * It is now possible to use the 'document' command to document user-defined commands.
     * Support for memory tag data for AArch64 MTE. 
    

  • Support Removal notices:

     * DBX mode has been removed.
     * Support for building against Python version 2 has been removed. It is now only possible to build GDB against Python 3.
     * Support for the following commands has been removed:
    
     * set debug aix-solib on|off
     * show debug aix-solib
     * set debug solib-frv on|off
     * show debug solib-frv
    
     * Use the 'set/show debug solib' commands instead.
