*** 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.
+
maint set|show per-command
maint set|show per-command space
maint set|show per-command time
* 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.
+set debug nios2
+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
+ trace-buffer-size -1" and "set height unlimited" is now an alias for
+ "set height 0".
+
+* New command-line options
+--configuration
+ Display the details of GDB configure-time options.
+
* The command 'tsave' can now support new option '-ctf' to save trace
buffer in Common Trace Format.
+* Newly installed $prefix/bin/gcore acts as a shell interface for the
+ GDB command gcore.
+
+* GDB now implements the the C++ 'typeid' operator.
+
+* The new convenience variable $_exception holds the exception being
+ thrown or caught at an exception-related catchpoint.
+
+* The exception-related catchpoints, like "catch throw", now accept a
+ regular expression which can be used to filter exceptions by type.
+
* MI changes
** 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.
+
+ ** GDBserver now supports hardware watchpoints on the MIPS GNU/Linux
+ target.
+
+* New 'z' formatter for printing and examining memory, this displays the
+ value as hexadecimal zero padded on the left to the size of the type.
+
*** Changes in GDB 7.6
* Target record has been renamed to record-full.
Release versions, on the other hand, are built without -lmcheck
by default. The --enable-libmcheck/--disable-libmcheck configure
options allow the user to override that default.
+--with-babeltrace/--with-babeltrace-include/--with-babeltrace-lib
+ This configure option allows the user to build GDB with
+ libbabeltrace using which GDB can read Common Trace Format data.
* New commands (for set/show, see "New options" below)
** Memory changes are now notified using new async record
"=memory-changed".
** The data-disassemble command response will include a "fullname" field
- containing the absolute file name when GDB can determine it and source
- has been requested.
+ containing the absolute file name when source has been requested.
** New optional parameter COUNT added to the "-data-write-memory-bytes"
command, to allow pattern filling of memory areas.
** New commands "-catch-load"/"-catch-unload" added for intercepting
** Output of the "-trace-status" command includes a "trace-file" field
containing the name of the trace file being examined. This field is
optional, and only present when examining a trace file.
+ ** The "fullname" field is now always present along with the "file" field,
+ even if the file cannot be found by GDB.
* GDB now supports the "mini debuginfo" section, .gnu_debugdata.
You must have the LZMA library available when configuring GDB for this
Set the size of trace buffer. The remote stub reports support for this
packet to gdb's qSupported query.
+Qbtrace:bts
+ Enable Branch Trace Store (BTS)-based branch tracing for the current
+ thread. The remote stub reports support for this packet to gdb's
+ qSupported query.
+
+Qbtrace:off
+ Disable branch tracing for the current thread. The remote stub reports
+ support for this packet to gdb's qSupported query.
+
+qXfer:btrace:read
+ Read the traced branches for the current thread. The remote stub
+ reports support for this packet to gdb's qSupported query.
+
