GDB 16.1 released!<br>
<br>
Release 16.1 of GDB, the GNU Debugger, is now available. GDB is<br>
a source-level debugger for Ada, C, C++, Fortran, Go, Rust, and many<br>
other languages. GDB can target (i.e., debug programs running on)<br>
more than a dozen different processor architectures, and GDB itself<br>
can run on most popular GNU/Linux, Unix and Microsoft Windows variants.<br>
GDB is free (libre) software.<br>
<br>
You can download GDB from the GNU HTTPS server in the directory:<br>

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