christos | Import gdb-17.1, previous was 16.3
This version of GDB includes the following changes and enhancements:
* x86-64 CET shadow stack support
* Debugging Linux programs that use AArch64 Guarded Control Stacks
* GDB record feature now supports rv64gc architectures
* 'info threads' command support for two new options '-stopped' and
'-running' to limit the list of displayed threads.
* On Linux and FreeBSD, the addresses shown by the 'info
sharedlibrary' command are now for the full memory range
allocated to the shared library.
* Linux checkpoints now work with multiple inferiors
* Improved linker namespace support
* Warnings and error messages now start with an emoji (warning
sign, or cross mark) if supported by the host charset.
Configurable.
* Built-in support for TLS on Linux as backup when libthread_db is
not available. Supported on the x86_64, aarch64, ppc64, s390x,
and riscv architectures, when compiled with GLIBC or MUSL.
* New command "set riscv numeric-register-names" to display
risc-v registers using their numeric names instead of their
ABI names.
* The Alpha target now supports target descriptions.
Python API enhancements:
* New class gdb.Color for dealing with colors, and new constant
gdb.PARAM_COLOR
* New gdb.ParameterPrefix class, to create new 'set/show' command
prefixes.
* New attribute gdb.Value.is_unavailable, this checks for
unavailability like gdb.Value.is_optimized_out checks for
optimized out values.
* New gdb.warning() function to print a warning message, with
GDB's standard 'warning' prefix (see emoji support entry below)
* gdb.execute has an additional 'styling' argument.
* Prefix commands (gdb.Command sub-classes) that don't have an
invoke method now behave like builtin prefix commands when
invoked without a sub-command name.
* Setting the documentation string (__doc__) of a gdb.Parameter
sub-class to the empty string, means GDB will only display the
set_doc or show_doc strings in the set/show help output.
Guile API enhancements:
* New type for dealing with colors and constant PARAM_COLOR
* Prefix commands (using make-command) that don't have a #:invoke
property will now behave like builtin prefix commands when
invoked without a sub-command name.
* Eliding the #:doc string from make-parameter now means that
GDB will use a default documentation string.
* Setting #:doc to the empty string for make-parameter means GDB
will only display the #:set_doc or #:show_doc strings in the
set/show help output.
Debugger Adapter Protocol changes:
* GDB now supports the "completions" request.
* New "--binary-output" command line option to disable LF
translations (Windows only)
New convenience variables:
* $_colorsupport providing a comma-separated list of color space
names supported by the terminal.
* $linker_namespace_count and $_linker_namespace provide the list
of active linker namespaces.
Remote package additions and changes:
* New 'binary-upload+' value in qSupported reply
* The 'vFile:stat' command implementation has been corrected to
use stat rather than lstat.
* New vFile:lstat packet, useful for handling symbolic links
* Support for the "id_str" attribute in 'qXfer:threads:read' XML
answer.
GDB/MI changes:
* The =library-unloaded event now includes the 'ranges' field and
the 'still-in-use' field.
Configure changes:
* Ability to select which file formats to include support for
* New option --disable-gdb-compile to disable support for the
compile subsystem.
* New option --disable-gdb-dwarf-support to disable support for
DWARF debug information in GDB.
* New option --disable-gdb-mdebug-support to disable support for
mdebug/ecoff debug information.
Incompatible changes:
* Support for Python versions older than 3.4 has been removed
* Support for stabs debugging format and the a.out/dbx object
format is deprecated, and will be removed in GDB 18.
* UST (static tracepoint) gdbserver support has been removed

January 18th, 2025: GDB 16.1 Released!
The latest version of GDB, version 16.1, is available for download.
This version of GDB includes the following changes and enhancements:
record/replay support now available on loongarch*-linux*
GDB now supports watchpoints for tagged data pointers.
MTE (Memory Tagging Extension) debugging is now supported on AArch64
baremetal.
New bash script gstack uses GDB to print stack traces of running
processes.
Enhanced breakpoint support
For breakpoints that are created in the 'pending' state, any
'thread' or 'task' keywords are parsed at the time the breakpoint
is created, rather than at the time the breakpoint becomes
non-pending.
Thread-specific breakpoints are only inserted into the program
space in which the thread of interest is running.
Enhanced Intel Processor Trace support
Support for printing of asynchronous events
Support for printing of ptwrite payloads
Changed commands
The "remove-symbol-file -a ADDRESS" command now accepts a full
expression as the ADDRESS.
The "show configuration" command now prints the version of GNU
readline that GDB is using.
The "maintenance print remote-registers" now provides an
"Expedited" column indicating which registers were included in
the last stop reply packet received by GDB.
Various command taking filenames as argument now require file
names to be quoted if the argument contains white spaces or
quote characters.
Python API changes
New module gdb.missing_objfile that facilitates dealing
with missing objfiles when opening a core-file. GDB
commands to query, enable and disable handlers created
using this API have also been added.
New event gdb.tui_enabled.
Added the gdb.Symbol.is_artificial attribute.
New gdb.record.clear function to clear the trace data
of the current recording.
The 'signed' argument to gdb.Architecture.integer_type()
will no longer accept non-bool types.
The gdb.MICommand.installed property can only be set
to True or False.
The 'qualified' argument to gdb.Breakpoint constructor
will no longer accept non-bool types.
Debugger Adapter Protocol changes
The "scopes" request will now return a scope holding
global variables from the stack frame's compilation
unit.
The "scopes" request will return a "returnValue" scope
holding the return value from the latest "stepOut"
command, when appropriate.
The "launch" and "attach" requests were rewritten in
accordance with some clarifications to the spec. Now
they can be sent at any time after the "initialized"
event, but will not take effect (or send a response)
until after the "configurationDone" request has been
sent.
The "variables" request will not return artificial symbols.
Remote Protocol
New remote packet: vFile:stat
New remote packet: x addr,length
Miscellaneous
The Ada 'Object_Size attribute is now supported.
Styling now available for line numbers, GDB commands and header
lines of lists.
It is now possible to turn the warning emitted when specifying a
language that does not match the current frame off.
For ARM targets, the offset of the pc in the jmp_buf
has been fixed to match glibc 2.20 and later. This
should only matter when not using libc probes. This
may cause breakage when using an incompatible libc,
like uclibc or newlib, or an older glibc.
Deprecated or removed
Support for QNX Neutrino has been removed
Support for Nios II targets has been removed
Support for Intel MPX has been removed
See the NEWS file for a more complete and detailed list of what this
release includes.
