An update that solves three vulnerabilities and contains one feature can now be
installed.
Description:
This update for gdb fixes the following issues:
o 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:
o This version of GDB includes the following changes and enhancements:
o 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*
o The Windows native target now supports target async.
o Floating-point support has now been added on LoongArch GNU/Linux.
o 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.
o 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.
o 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.
o 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.
