(Organized release by release)
*** Changes since GDB 7.9
-=======
+
+* Support for process record-replay and reverse debugging on aarch64*-linux*
+ targets has been added. GDB now supports recording of A64 instruction set
+ including advance SIMD instructions.
* GDB now honors the content of the file /proc/PID/coredump_filter
(PID is the process ID) on GNU/Linux systems. This file can be used
present in the debug info. This typically includes the compiler version
and may include things like its command line arguments.
+* The "info dll", an alias of the "info sharedlibrary" command,
+ is now available on all platforms.
+
* Directory names supplied to the "set sysroot" commands may be
prefixed with "target:" to tell GDB to access shared libraries from
the target system, be it local or remote. This replaces the prefix
the operating system) when starting processes remotely, and when
attaching to already-running local or remote processes.
+* GDB now supports automatic location and retrieval of executable
+ files from remote targets. Remote debugging can now be initiated
+ using only a "target remote" or "target extended-remote" command
+ (no "set sysroot" or "file" commands are required). See "New remote
+ packets" below.
+
+* The "dump" command now supports verilog hex format.
+
+* GDB now supports the vector ABI on S/390 GNU/Linux targets.
+
+* Guile Scripting
+
+ ** Memory ports can now be unbuffered.
+
* Python Scripting
** gdb.Objfile objects have a new attribute "username",
which is the name of the objfile as specified by the user,
without, for example, resolving symlinks.
** You can now write frame unwinders in Python.
+ ** gdb.Type objects have a new method "optimized_out",
+ returning optimized out gdb.Value instance of this type.
+ ** gdb.Value objects have new methods "reference_value" and
+ "const_value" which return a reference to the value and a
+ "const" version of the value respectively.
* New commands
record bts
Start branch trace recording using Branch Trace Store (BTS) format.
+compile print
+ Evaluate expression by using the compiler and print result.
+
+tui enable
+tui disable
+ Explicit commands for enabling and disabling tui mode.
+
+show mpx bound
+set mpx bound on i386 and amd64
+ Support for bound table investigation on Intel(R) MPX enabled applications.
+
* New options
+set debug dwarf-die
+ Renamed from "set debug dwarf2-die".
+show debug dwarf-die
+ Renamed from "show debug dwarf2-die".
+
+set debug dwarf-read
+ Renamed from "set debug dwarf2-read".
+show debug dwarf-read
+ Renamed from "show debug dwarf2-read".
+
+maint set dwarf always-disassemble
+ Renamed from "maint set dwarf2 always-disassemble".
+maint show dwarf always-disassemble
+ Renamed from "maint show dwarf2 always-disassemble".
+
+maint set dwarf max-cache-age
+ Renamed from "maint set dwarf2 max-cache-age".
+maint show dwarf max-cache-age
+ Renamed from "maint show dwarf2 max-cache-age".
+
+set debug dwarf-line
+show debug dwarf-line
+ Control display of debugging info regarding DWARF line processing.
+
set max-completions
show max-completions
Set the maximum number of candidates to be considered during
The obtained size may differ from the requested size. Use "info
record" to see the obtained buffer size.
+set debug linux-namespaces
+show debug linux-namespaces
+ Control display of debugging info regarding Linux namespaces.
+
* The command 'thread apply all' can now support new option '-ascending'
to call its specified command for all threads in ascending order.
vFile:fstat:
Return information about files on the remote system.
+qXfer:exec-file:read
+ Return the full absolute name of the file that was executed to
+ create a process running on the remote system.
+
+vFile:setfs:
+ Select the filesystem on which vFile: operations with filename
+ arguments will operate. This is required for GDB to be able to
+ access files on remote targets where the remote stub does not
+ share a common filesystem with the inferior(s).
+
+fork stop reason
+ Indicates that a fork system call was executed.
+
+vfork stop reason
+ Indicates that a vfork system call was executed.
+
+vforkdone stop reason
+ Indicates that a vfork child of the specified process has executed
+ an exec or exit, allowing the vfork parent to resume execution.
+
+fork-events and vfork-events features in qSupported
+ The qSupported packet allows GDB to request support for fork and
+ vfork events using new 'gdbfeatures' fork-events and vfork-events,
+ and the qSupported response can contain the corresponding
+ 'stubfeatures'. Set and show commands can be used to display
+ whether these features are enabled.
+
+* Extended-remote fork events
+
+ ** GDB now has support for fork events on extended-remote Linux
+ targets. For targets with Linux kernels 2.5.60 and later, this
+ enables follow-fork-mode and detach-on-fork for both fork and
+ vfork, as well as fork and vfork catchpoints.
+
* The info record command now shows the recording format and the
branch tracing configuration for the current thread when using
the btrace record target.
HP/PA running HP-UX hppa*-*-hpux*
Itanium running HP-UX ia64-*-hpux*
+*** Changes in GDB 7.9.1
+
+* Python Scripting
+
+ ** Xmethods can now specify a result type.
+
*** Changes in GDB 7.9
* GDB now supports hardware watchpoints on x86 GNU Hurd.
