*** Changes since GDB 8.2
+* GDB now has experimental support for the compilation and injection of
+ C++ source code into the inferior. This beta release does not include
+ support for several language features, such as templates, constructors,
+ and operators.
+
+ This feature requires GCC 7.1 or higher built with libcp1.so
+ (the C++ plug-in).
+
* GDB and GDBserver now support IPv6 connections. IPv6 addresses
can be passed using the '[ADDRESS]:PORT' notation, or the regular
'ADDRESS:PORT' method.
* DWARF index cache: GDB can now automatically save indices of DWARF
symbols on disk to speed up further loading of the same binaries.
+* GDB in batch mode now exits with status 1 if the last command to be
+ executed failed.
+
+* Changes to the "frame", "select-frame", and "info frame" CLI
+ commands. These commands all now take a frame specification which
+ is either a frame level, or one of the keywords 'level', 'address',
+ 'function', or 'view' followed by a parameter. Selecting a frame by
+ address, or viewing a frame outside the current backtrace now
+ requires the use of a keyword. Selecting a frame by level is
+ unchanged. The MI comment "-stack-select-frame" is unchanged.
+
* New commands
+set debug compile-cplus-types
+show debug compile-cplus-types
+ Control the display of debug output about type conversion in the
+ C++ compile feature. Commands have no effect while compiliong
+ for other languages.
+
+set debug skip
+show debug skip
+ Control whether debug output about files/functions skipping is
+ displayed.
+
frame apply [all | COUNT | -COUNT | level LEVEL...] [FLAG]... COMMAND
Apply a command to some frames.
FLAG arguments allow to control what output to produce and how to handle
maint show dwarf unwinders
Control whether DWARF unwinders can be used.
+info proc files
+ Display a list of open files for a process.
+
* Changed commands
+target remote FILENAME
+target extended-remote FILENAME
+ If FILENAME is a Unix domain socket, GDB will attempt to connect
+ to this socket instead of opening FILENAME as a character device.
+
thread apply [all | COUNT | -COUNT] [FLAG]... COMMAND
The 'thread apply' command accepts new FLAG arguments.
FLAG arguments allow to control what output to produce and how to handle
errors raised when applying COMMAND to a thread.
+* MI changes
+
+ ** The '-data-disassemble' MI command now accepts an '-a' option to
+ disassemble the whole function surrounding the given program
+ counter value or function name. Support for this feature can be
+ verified by using the "-list-features" command, which should
+ contain "data-disassemble-a-option".
+
+ ** Command responses and notifications that include a frame now include
+ the frame's architecture in a new "arch" attribute.
+
+* New native configurations
+
+GNU/Linux/RISC-V riscv*-*-linux*
+
+* New targets
+
+GNU/Linux/RISC-V riscv*-*-linux*
+CSKY ELF csky*-*-elf
+CSKY GNU/LINUX csky*-*-linux
+
+* Python API
+
+ ** The gdb.Inferior type has a new 'progspace' property, which is the program
+ space associated to that inferior.
+
+ ** The gdb.Progspace type has a new 'objfiles' method, which returns the list
+ of objfiles associated to that program space.
+
+* Configure changes
+
+--enable-ubsan
+
+ Enable or disable the undefined behavior sanitizer. Release
+ versions of GDB disable this by default if it is available, but
+ development versions enable it. Enabling this can cause a
+ performance penalty. The undefined behavior sanitizer was first
+ introduced in GCC 4.9.
+
*** Changes in GDB 8.2
* The 'set disassembler-options' command now supports specifying options
* C expressions can now use _Alignof, and C++ expressions can now use
alignof.
+* Support for SVE on AArch64 Linux. Note that GDB does not detect changes to
+ the vector length while the process is running.
+
* New commands
