*** Changes since GDB 7.6
+* Python scripting
+
+ ** Frame filters and frame decorators have been added.
+
* New targets
Nios II ELF nios2*-*-elf
Nios II GNU/Linux nios2*-*-linux
+Texas Instruments MSP430 msp430*-*-elf
* New commands:
catch rethrow
Like "catch throw", but catches a re-thrown exception.
+maint check-psymtabs
+ Renamed from old "maint check-symtabs".
+maint check-symtabs
+ Perform consistency checks on symtabs.
+maint expand-symtabs
+ Expand symtabs matching an optional regexp.
show configuration
Display the details of GDB configure-time options.
* New options
+set print raw frame-arguments
+show print raw frame-arguments
+ Set/show whether to print frame arguments in raw mode,
+ disregarding any defined pretty-printers.
+
set remote trace-status-packet
show remote trace-status-packet
Set/show the use of remote protocol qTStatus packet.
show debug nios2
Control display of debugging messages related to Nios II targets.
+set range-stepping
+show range-stepping
+ Control whether target-assisted range stepping is enabled.
+
* You can now use a literal value 'unlimited' for options that
interpret 0 or -1 as meaning "unlimited". E.g., "set
trace-buffer-size unlimited" is now an alias for "set
** The -trace-save MI command can optionally save trace buffer in Common
Trace Format now.
+ ** The new command -dprintf-insert sets a dynamic printf breakpoint.
+
+ ** The command -data-list-register-values now accepts an optional
+ "--skip-unavailable" option. When used, only the available registers
+ are displayed.
+
+ ** The new command -trace-frame-collected dumps collected variables,
+ computed expressions, tvars, memory and registers in a traceframe.
+
+* New system-wide configuration scripts
+ A GDB installation now provides scripts suitable for use as system-wide
+ configuration scripts for the following systems:
+ ** ElinOS
+ ** Wind River Linux
+
+* GDB now supports target-assigned range stepping with remote targets.
+ This improves the performance of stepping source lines by reducing
+ the number of control packets from/to GDB. See "New remote packets"
+ below.
+
+* GDB now understands the element 'tvar' in the XML traceframe info.
+ It has the id of the collected trace state variables.
+
+* New remote packets
+
+vCont;r
+
+ The vCont packet supports a new 'r' action, that tells the remote
+ stub to step through an address range itself, without GDB
+ involvemement at each single-step.
+
+qXfer:libraries-svr4:read's annex
+ The previously unused annex of the qXfer:libraries-svr4:read packet
+ is now used to support passing an argument list. The remote stub
+ reports support for this argument list to GDB's qSupported query.
+ The defined arguments are "start" and "prev", used to reduce work
+ necessary for library list updating, resulting in significant
+ speedup.
+
+* New features in the GDB remote stub, GDBserver
+
+ ** GDBserver now supports target-assisted range stepping. Currently
+ enabled on x86/x86_64 GNU/Linux targets.
+
+ ** GDBserver now adds element 'tvar' in the XML in the reply to
+ 'qXfer:traceframe-info:read'. It has the id of the collected
+ trace state variables.
+
