*** Changes since GDB 12
+* "info breakpoints" now displays enabled breakpoint locations of
+ disabled breakpoints as in the "y-" state. For example:
+
+ (gdb) info breakpoints
+ Num Type Disp Enb Address What
+ 1 breakpoint keep n <MULTIPLE>
+ 1.1 y- 0x00000000000011b6 in ...
+ 1.2 y- 0x00000000000011c2 in ...
+ 1.3 n 0x00000000000011ce in ...
+
+* Support for Thread Local Storage (TLS) variables on FreeBSD arm and
+ aarch64 architectures.
+
* GDB now supports hardware watchpoints on FreeBSD/Aarch64.
* Remove support for building against Python 2, it is now only possible to
build GDB against Python 3.
+* DBX mode has been removed.
+
+* GDB now honours the DWARF prologue_end line-table entry flag the compiler can
+ emit to indicate where a breakpoint should be placed to break in a function
+ past its prologue.
+
+* Python API
+
+ ** GDB will now reformat the doc string for gdb.Command and
+ gdb.Parameter sub-classes to remove unnecessary leading
+ whitespace from each line before using the string as the help
+ output.
+
+* New commands
+
+maintenance set ignore-prologue-end-flag on|off
+maintenance show ignore-prologue-end-flag
+ This setting, which is off by default, controls whether GDB ignores the
+ PROLOGUE-END flag from the line-table when skipping prologue. This can be
+ used to force GDB to use prologue analyzers if the line-table is constructed
+ from erroneous debug information.
+
+* Changed commands
+
+maintenance info line-table
+ Add a PROLOGUE-END column to the output which indicates that an
+ entry corresponds to an address where a breakpoint should be placed
+ to be at the first instruction past a function's prologue.
+
* Python API
** New function gdb.format_address(ADDRESS, PROGSPACE, ARCHITECTURE),
This is the same format that GDB uses when printing address, symbol,
and offset information from the disassembler.
+ ** New function gdb.current_language that returns the name of the
+ current language. Unlike gdb.parameter('language'), this will
+ never return 'auto'.
+
+ ** New method gdb.Frame.language that returns the name of the
+ frame's language.
+
*** Changes in GDB 12
* DBX mode is deprecated, and will be removed in GDB 13
values for this follow the values that can be passed to the GNAT
compiler via the '-gnati' option. The default is ISO-8859-1.
+tui layout
+tui focus
+tui refresh
+tui window height
+ These are the new names for the old 'layout', 'focus', 'refresh',
+ and 'winheight' tui commands respectively. The old names still
+ exist as aliases to these new commands.
+
+tui window width
+winwidth
+ The new command 'tui window width', and the alias 'winwidth' allow
+ the width of a tui window to be adjusted when windows are laid out
+ in horizontal mode.
+
+set debug tui on|off
+show debug tui
+ Control the display of debug output about GDB's tui.
+
* Changed commands
print
This command now includes information about the width of the tui
windows in its output.
+layout
+focus
+refresh
+winheight
+ These commands are now aliases for the 'tui layout', 'tui focus',
+ 'tui refresh', and 'tui window height' commands respectively.
+
* GDB's Ada parser now supports an extension for specifying the exact
byte contents of a floating-point literal. This can be useful for
setting floating-point registers to a precise value without loss of
the current CPSR value for instructions without symbols; previous
versions of GDB behaved as if "set arm fallback-mode arm".
+set arm unwind-secure-frames
+ Enable unwinding from Non-secure to Secure mode on Cortex-M with
+ Security extension.
+ This can trigger security exceptions when unwinding exception stacks.
+
set disable-randomization
show disable-randomization
Standalone programs run with the virtual address space randomization enabled
