What has changed in GDB?
(Organized release by release)
-*** Changes since GDB 8.1
+*** Changes since GDB 8.2
+
+* 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.
+
+* New commands
+
+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
+ errors raised when applying COMMAND to a frame.
+
+taas COMMAND
+ Apply a command to all threads (ignoring errors and empty output).
+ Shortcut for 'thread apply all -s COMMAND'.
+
+faas COMMAND
+ Apply a command to all frames (ignoring errors and empty output).
+ Shortcut for 'frame apply all -s COMMAND'.
+
+tfaas COMMAND
+ Apply a command to all frames of all threads (ignoring errors and empty
+ output).
+ Shortcut for 'thread apply all -s frame apply all -s COMMAND'.
+
+maint set dwarf unwinders (on|off)
+maint show dwarf unwinders
+ Control whether DWARF unwinders can be used.
+
+* Changed commands
+
+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.
+
+* New native configurations
+
+GNU/Linux/RISC-V riscv*-*-linux*
+
+* New targets
+
+GNU/Linux/RISC-V riscv*-*-linux*
+
+*** Changes in GDB 8.2
+
+* The 'set disassembler-options' command now supports specifying options
+ for the MIPS target.
+
+* The 'symbol-file' command now accepts an '-o' option to add a relative
+ offset to all sections.
+
+* Similarly, the 'add-symbol-file' command also accepts an '-o' option to add
+ a relative offset to all sections, but it allows to override the load
+ address of individual sections using '-s'.
+
+* The 'add-symbol-file' command no longer requires the second argument
+ (address of the text section).
* The endianness used with the 'set endian auto' mode in the absence of
an executable selected for debugging is now the last endianness chosen
or by inferring from the last executable used, rather than the startup
default.
+* The pager now allows a "c" response, meaning to disable the pager
+ for the rest of the current command.
+
* The commands 'info variables/functions/types' now show the source line
numbers of symbol definitions when available.
Controls the processor to be used for enabling errata workarounds for
branch trace decode.
+maint check libthread-db
+ Run integrity checks on the current inferior's thread debugging
+ library
+
+maint set check-libthread-db (on|off)
+maint show check-libthread-db
+ Control whether to run integrity checks on inferior specific thread
+ debugging libraries as they are loaded. The default is not to
+ perform such checks.
+
* Python API
** Type alignment is now exposed via the "align" attribute of a gdb.Type.
gdb.set_convenience_variable can be used to get and set the value
of convenience variables.
+ ** A gdb.Parameter will no longer print the "set" help text on an
+ ordinary "set"; instead by default a "set" will be silent unless
+ the get_set_string method returns a non-empty string.
+
* New targets
RiscV ELF riscv*-*-elf
the tradeoff that there is a possibility of false hits being
reported.
+* Configure changes
+
+--enable-codesign=CERT
+ This can be used to invoke "codesign -s CERT" after building gdb.
+ This option is useful on macOS, where code signing is required for
+ gdb to work properly.
+
+--disable-gdbcli has been removed
+ This is now silently accepted, but does nothing.
+
*** Changes in GDB 8.1
* GDB now supports dynamically creating arbitrary register groups specified
