gdb-13.1

[Douglas R. Reno]

New major version

[Xi Ruoyao]

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.
• FreeBSD:
  • Arm and AArch64: Support for Thread Local Storage (TLS) variables
  • Hardware watchpoint support on AArch64 FreeBSD
• 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.

See the NEWS file for a more complete and detailed list of what this release includes.
