-right, and in the long term it is worth it to the GNU project, and
-probably to you individually as well.
-
-If you make substantial changes, you'll have to file a copyright
-assignment with the Free Software Foundation before we can produce a
-release that includes your changes.  Send mail requesting the copyright
-assignment to gnu@prep.ai.mit.edu.  Do this early, like before the
-changes actually work, or even before you start them, because a manager
-or lawyer on your end will probably make this a slow process.
-
-Please code according to the GNU coding standards.  If you do not have
-a copy, you can request one by sending mail to gnu@prep.ai.mit.edu.
-
-Please try to avoid making machine-specific changes to
-machine-independent files.  If this is unavoidable, put a hook in the
-machine-independent file which calls a (possibly) machine-dependent
-macro (for example, the IGNORE_SYMBOL macro can be used for any
-symbols which need to be ignored on a specific machine.  Calling
-IGNORE_SYMBOL in dbxread.c is a lot cleaner than a maze of #if
-defined's).  The machine-independent code should do whatever "most"
-machines want if the macro is not defined in param.h.  Using #if
-defined can sometimes be OK (e.g. SET_STACK_LIMIT_HUGE) but should be
-conditionalized on a specific feature of an operating system (set in
-tm.h or xm.h) rather than something like #if defined(vax) or #if
-defined(SYSV).  If you use an #ifdef on some symbol that is defined
-in a header file (e.g. #ifdef TIOCSETP), *please* make sure that you
-have #include'd the relevant header file in that module!
-
-There is a list of all known `feature-test macros' in gdbint.texinfo.
-Each such macro should be defined (or left undefined) in a host-dependent,
-target-dependent, or native-dependent include file.  Not all of the
-macros are cleanly separated this way, yet.  As you make changes, move
-the code toward cleanliness.
-
-It is better to replace entire routines which may be system-specific,
-rather than put in a whole bunch of hooks which are probably not going
-to be helpful for any purpose other than your changes.  For example,
-if you want to modify dbxread.c to deal with DBX debugging symbols
-which are in COFF files rather than BSD a.out files, do something
-along the lines of a macro GET_NEXT_SYMBOL, which could have
-different definitions for COFF and a.out, rather than trying to put
-the necessary changes throughout all the code in dbxread.c that
-currently assumes BSD format.
-
-When generalizing GDB along a particular interface, please use an
-attribute-struct rather than inserting tests or switch statements
-everywhere.  For example, GDB has been generalized to handle multiple
-kinds of remote interfaces -- not by #ifdef's everywhere, but by
-defining the "target_ops" structure and having a current target (as
-well as a stack of targets below it, for memory references).  Whenever
-something needs to be done that depends on which remote interface we
-are using, a flag in the current target_ops structure is tested (e.g.
-`target_has_stack'), or a function is called through a pointer in the
-current target_ops structure.  In this way, when a new remote interface
-is added, only one module needs to be touched -- the one that actually
-implements the new remote interface.  Other examples of
-attribute-structs are BFD access to multiple kinds of object file
-formats, or GDB's access to multiple source languages.
-
-Please avoid duplicating code.  For example, in GDB 3.x all the stuff
-in infptrace.c was duplicated in *-dep.c, and so changing something
-was very painful.  In GDB 4.x, these have all been consolidated
-into infptrace.c.  infptrace.c can deal with variations between
-systems the same way any system-independent file would (hooks, #if
-defined, etc.), and machines which are radically different don't need
-to use infptrace.c at all.  The same was true of core_file_command
-and exec_file_command.

+GDB Testsuite
+=============
+
+There is a dejagnu based testsuite available for testing your newly
+built gdb, or for regression testing gdb's with local modifications.
+The testsuite is distributed separately from the base gdb distribution
+for the convenience of people that wish to get either gdb or the testsuite
+separately.
+
+The name of the testsuite is gdb-4.9-testsuite.tar.z.  You unpack it in the
+same directory in which you unpacked the base gdb distribution, and it
+will create and populate the directory gdb-4.9/gdb/testsuite.
+
+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-4.9/gdb		(assuming you also unpacked gdb)
+	make check
 
-If gdb is limping on your machine, this is the preferred way to get it
-fully functional.  Be warned that in some ancient Unix systems, like
-Ultrix 4.0, a program can't be running in one process while it is being
-debugged in another.  Rather than doing "./gdb ./gdb", which works on
-Suns and such, you can copy gdb to gdb2 and then do "./gdb ./gdb2".
+or
 
-When you run gdb in the gdb source directory, it will read a ".gdbinit"
-file that sets up some simple things to make debugging gdb easier.  The
-"info" command, when executed without a subcommand in a gdb being
-debugged by gdb, will pop you back up to the top level gdb.  See
-.gdbinit for details.
+  (2)	cd gdb-4.9/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)
 
-I strongly recommend printing out the reference card and using it.
-Send reference-card suggestions to bug-gdb@prep.ai.mit.edu, just like bugs.
+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
+'standalone', without it being part of the gdb source tree.
 
-If you use emacs, you will probably want to do a "make TAGS" after you
-configure your distribution; this will put the machine dependent
-routines for your local machine where they will be accessed first by a
-M-period.
+See the dejagnu documentation for further details.
 
-Also, make sure that you've either compiled gdb with your local cc, or
-have run `fixincludes' if you are compiling with gcc.
