*** Changes since GDB 6.6
+* When the Text User Interface (TUI) is not configured, GDB will now
+recognize the -tui command-line option and print a message that the TUI
+is not supported.
+
* The GDB remote stub, gdbserver, now has lower overhead for high
frequency signals (e.g. SIGALRM) via the QPassSignals packet.

* Arrays of explicitly SIGNED or UNSIGNED CHARs are now printed as arrays
- of numbers.

* Target descriptions can now describe target-specific registers,
for architectures which have implemented the support (currently
-only ARM).
+only ARM and MIPS).
* GDB and the GDB remote stub, gdbserver, now support the XScale
iWMMXt coprocessor.
* GDB can now step into C++ functions which are called through thunks.
+* GDB for the Cell/B.E. SPU now supports overlay debugging.
+
+* The GDB remote protocol "qOffsets" packet can now honor ELF segment
+layout. It also supports a TextSeg= and DataSeg= response when only
+segment base addresses (rather than offsets) are available.
+
+* The /i format now outputs any trailing branch delay slot instructions
+immediately following the last instruction within the count specified.
+
* New commands
+set remoteflow
+show remoteflow
+ Enable or disable hardware flow control (RTS/CTS) on the serial port
+ when debugging using remote targets.
+
set mem inaccessible-by-default
show mem inaccessible-by-default
If the target supplies a memory map, for instance via the remote
general version of "set solib-absolute-prefix", which is now
an alias to "set sysroot".
+info spu
+ Provide extended SPU facility status information. This set of
+ commands is available only when debugging the Cell/B.E. SPU
+ architecture.
+
* New native configurations
OpenBSD/sh sh*-*openbsd*
Read an XML target description from the target, which describes its
features.
+qXfer:spu:read:
+qXfer:spu:write:
+ Read or write contents of an spufs file on the target system. These
+ packets are available only on the Cell/B.E. SPU architecture.
+
* Removed targets
Support for these obsolete configurations has been removed.
GDB could work with an older version of Guile to debug
the interpreter and Scheme programs running in it.
+set mips stack-arg-size
+set mips saved-gpreg-size
+
+ Use "set mips abi" to control parameter passing for MIPS.
