*** 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.
target's overall architecture. GDB can read a description from
a local file or over the remote serial protocol.
+* 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 and MIPS).
+
+* GDB and the GDB remote stub, gdbserver, now support the XScale
+iWMMXt coprocessor.
+
+* The GDB remote stub, gdbserver, has been updated to support
+ARM Windows CE (mingw32ce) debugging, and GDB Windows CE support
+has been rewritten to use the standard GDB remote protocol.
+
+* 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.
+
* 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*
OpenBSD/sh sh*-*-openbsd*
MIPS64 GNU/Linux (gdbserver) mips64-linux-gnu
+Toshiba Media Processor mep-elf
* New remote packets
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.

+target ocd
+
+ Support for a Macraigor serial interface to on-chip debugging.
+ GDB does not directly support the newer parallel or USB
+ interfaces.
+
+DWARF 1 support
+
+ A debug information format. The predecessor to DWARF 2 and
+ DWARF 3, which are still supported.
+
+Support for the HP aCC compiler on HP-UX/PA-RISC
+
+ SOM-encapsulated symbolic debugging information, automatic
+ invocation of pxdb, and the aCC custom C++ ABI. This does not
+ affect HP-UX for Itanium or GCC for HP-UX/PA-RISC. Code compiled
+ with aCC can still be debugged on an assembly level.

+ in debugging information.
+
+Scheme support
+
+ 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.
+
*** Changes in GDB 6.6
* New targets
* The "set trust-readonly-sections" command works again. This command was
broken in GDB 6.3, 6.4, and 6.5.
+* The "load" command now supports writing to flash memory, if the remote
+stub provides the required support.
+
* Support for GNU/Linux Thread Local Storage (TLS, per-thread variables) no
longer requires symbolic debug information (e.g. DWARF-2).
Fetch an OS auxilliary vector from the remote stub. This packet is a
more efficient replacement for qPart:auxv:read.
+qXfer:memory-map:read:
+ Fetch a memory map from the remote stub, including information about
+ RAM, ROM, and flash memory devices.
+
+vFlashErase:
+vFlashWrite:
+vFlashDone:
+ Erase and program a flash memory device.
+
* Removed remote packets
