What has changed since GDB-3.5?
(Organized release by release)

*** Changes in GDB-4.13:
-* New "complete" command for use by emacs.
+* New "complete" command
+
+This lists all the possible completions for the rest of the line, if it
+were to be given as a command itself. This is intended for use by emacs.
-* "set prompt" no longer adds a space for you after the prompt you set. This
+* Trailing space optional in prompt
+
+"set prompt" no longer adds a space for you after the prompt you set. This
allows you to set a prompt which ends in a space or one that does not.
+* Breakpoint hit counts
+
+"info break" now displays a count of the number of times the breakpoint
+has been hit. This is especially useful in conjunction with "ignore"; you
+can ignore a large number of breakpoint hits, look at the breakpoint info
+to see how many times the breakpoint was hit, then run again, ignoring one
+less than that number, and this will get you quickly to the last hit of
+that breakpoint.
+
+* Ability to stop printing at NULL character
+
+"set print null-stop" will cause GDB to stop printing the characters of
+an array when the first NULL is encountered. This is useful when large
+arrays actually contain only short strings.
+
+* Shared library breakpoints
+
+In SunOS 4.x, SVR4, and Alpha OSF/1 configurations, you can now set
+breakpoints in shared libraries before the executable is run.
+
+* Hardware watchpoints
+
+There is a new hardware breakpoint for the watch command for sparclite
+targets. See gdb/sparclite/hw_breakpoint.note.
+
+Hardware watchpoints are also now supported under Linux.
+
+* Annotations
+
+Annotations have been added. These are for use with graphical interfaces,
+and are still experimental. Currently only gdba.el uses these.
+
+* Improved Irix 5 support
+
+GDB now works properly with Irix 5.2.
+
+* Improved HPPA support
+
+GDB now works properly with the latest GCC and GAS.
+
+* New native configurations
+
+Sequent PTX4 i[34]86-sequent-ptx4
+HPPA running OSF/1 hppa*-*-osf*
+Atari TT running SVR4 m68*-*-sysv4*
+RS/6000 LynxOS rs6000-*-lynxos*
+
+* New targets
+
+OS/9000 i[34]86-*-os9k
+MIPS R4000 mips64*{,el}-*-{ecoff,elf}
+Sparc64 sparc64-*-*
+
+* Hitachi SH7000 and E7000-PC ICE support
+
+There is now support for communicating with the Hitachi E7000-PC ICE.
+This is available automatically when GDB is configured for the SH.
+
+* Fixes
+
+As usual, a variety of small fixes and improvements, both generic
+and configuration-specific. See the ChangeLog for more detail.

This is GDB, the GNU source-level debugger, presently running under un*x.
A summary of new features is in the file `NEWS'.
In this release, the GDB debugger sources, the generic GNU include
files, the BFD ("binary file description") library, the readline
library, and other libraries all have directories of their own

tools can share a common copy of these things. Be aware of variation
over time--for example don't try to build gdb with a copy of bfd from
a release other than the gdb release (such as a binutils or gas

order.

-The name of the testsuite is gdb-4.12-testsuite.tar.gz. You unpack it in the

Running the testsuite requires the prior installation of dejagnu, which
should be available via ftp. Once dejagnu is installed, you can run
the tests in one of two ways:
- (1) cd gdb-4.12/gdb (assuming you also unpacked gdb)
+ (1) cd gdb-4.13/gdb (assuming you also unpacked gdb)
make check
or
- (2) cd gdb-4.12/gdb/testsuite

make (builds the test executables)
make site.exp (builds the site specific file)
runtest -tool gdb GDB=../gdb (or GDB=<somepath> as appropriate)
The second method gives you slightly more control in case of problems with
building one or more test executables, in case you wish to remove some
test executables before running the tests, or if you are using the testsuite
