+
+Altos 3068 m68*-altos-*
+Convex c1-*-*, c2-*-*

+
+* Other news:
+
+* All MIPS configurations are multi-arched.
+
+Multi-arch support is enabled for all MIPS configurations.
+
+* GDB's version number moved to ``version.in''
+
+The Makefile variable VERSION has been replaced by the file
+``version.in''. People creating GDB distributions should update the
+contents of this file.
+
+* gdba.el deleted
+
+GUD support is now a standard part of the EMACS distribution.
+
+*** Changes in GDB 5.0:
+
+* Improved support for debugging FP programs on x86 targets
+
+Unified and much-improved support for debugging floating-point
+programs on all x86 targets. In particular, ``info float'' now
+displays the FP registers in the same format on all x86 targets, with
+greater level of detail.
+
+* Improvements and bugfixes in hardware-assisted watchpoints
+
+It is now possible to watch array elements, struct members, and
+bitfields with hardware-assisted watchpoints. Data-read watchpoints
+on x86 targets no longer erroneously trigger when the address is
+written.
+
+* Improvements in the native DJGPP version of GDB
+
+The distribution now includes all the scripts and auxiliary files
+necessary to build the native DJGPP version on MS-DOS/MS-Windows
+machines ``out of the box''.
+
+The DJGPP version can now debug programs that use signals. It is
+possible to catch signals that happened in the debuggee, deliver
+signals to it, interrupt it with Ctrl-C, etc. (Previously, a signal
+would kill the program being debugged.) Programs that hook hardware
+interrupts (keyboard, timer, etc.) can also be debugged.
+
+It is now possible to debug DJGPP programs that redirect their
+standard handles or switch them to raw (as opposed to cooked) mode, or
+even close them. The command ``run < foo > bar'' works as expected,
+and ``info terminal'' reports useful information about the debuggee's
+terminal, including raw/cooked mode, redirection, etc.
+
+The DJGPP version now uses termios functions for console I/O, which
+enables debugging graphics programs. Interrupting GDB with Ctrl-C
+also works.
+
+DOS-style file names with drive letters are now fully supported by
+GDB.
+
+It is now possible to debug DJGPP programs that switch their working
+directory. It is also possible to rerun the debuggee any number of
+times without restarting GDB; thus, you can use the same setup,
+breakpoints, etc. for many debugging sessions.
+
+* New native configurations
+
+ARM GNU/Linux arm*-*-linux*
+PowerPC GNU/Linux powerpc-*-linux*
+
+* New targets
+
+Motorola MCore mcore-*-*
+x86 VxWorks i[3456]86-*-vxworks*
+PowerPC VxWorks powerpc-*-vxworks*
+TI TMS320C80 tic80-*-*
+
+* OBSOLETE configurations
+
+Altos 3068 m68*-altos-*
+Convex c1-*-*, c2-*-*
+Pyramid pyramid-*-*
+ARM RISCix arm-*-* (as host)
+Tahoe tahoe-*-*
+
+Configurations that have been declared obsolete will be commented out,
+but the code will be left in place. If there is no activity to revive
+these configurations before the next release of GDB, the sources will
+be permanently REMOVED.
+
+* Gould support removed
+
+Support for the Gould PowerNode and NP1 has been removed.
+
+* New features for SVR4
+
+On SVR4 native platforms (such as Solaris), if you attach to a process
+without first loading a symbol file, GDB will now attempt to locate and
+load symbols from the running process's executable file.
+
+* Many C++ enhancements
+
+C++ support has been greatly improved. Overload resolution now works properly
+in almost all cases. RTTI support is on the way.
+
+* Remote targets can connect to a sub-program
+
+A popen(3) style serial-device has been added. This device starts a
+sub-process (such as a stand-alone simulator) and then communicates
+with that. The sub-program to run is specified using the syntax
+``|<program> <args>'' vis:
+
+ (gdb) set remotedebug 1
+ (gdb) target extended-remote |mn10300-elf-sim program-args
+
+* MIPS 64 remote protocol
+
+A long standing bug in the mips64 remote protocol where by GDB
+expected certain 32 bit registers (ex SR) to be transfered as 32
+instead of 64 bits has been fixed.
+
+The command ``set remote-mips64-transfers-32bit-regs on'' has been
+added to provide backward compatibility with older versions of GDB.
+
+* ``set remotebinarydownload'' replaced by ``set remote X-packet''
+
+The command ``set remotebinarydownload'' command has been replaced by
+``set remote X-packet''. Other commands in ``set remote'' family
+include ``set remote P-packet''.
+
+* Breakpoint commands accept ranges.
+
+The breakpoint commands ``enable'', ``disable'', and ``delete'' now
+accept a range of breakpoints, e.g. ``5-7''. The tracepoint command
+``tracepoint passcount'' also accepts a range of tracepoints.
+
+* ``apropos'' command added.
+
+The ``apropos'' command searches through command names and
+documentation strings, printing out matches, making it much easier to
+try to find a command that does what you are looking for.
+
+* New MI interface
+
+A new machine oriented interface (MI) has been added to GDB. This
+interface is designed for debug environments running GDB as a separate
+process. This is part of the long term libGDB project. See the
+"GDB/MI" chapter of the GDB manual for further information. It can be
+enabled by configuring with:
+
+ .../configure --enable-gdbmi
