-As a first possibility to cut down the number of tests that are run it is

-in the @file{gcc} subdirectory of the object directory.  To further cut down the

+in the @file{gcc} subdirectory of the object directory.  You can also
+just run @samp{make check} in a subdirectory of the object directory.
+
+
+A more selective way to just run all @command{gcc} execute tests in the
+testsuite is to use
 
 @example
     make check-gcc RUNTESTFLAGS="execute.exp @var{other-options}"
 @end example
 
-This will run all @command{gcc} execute tests in the testsuite.
+Likewise, in order to run only the @command{g++} ``old-deja'' tests in
+the testsuite with filenames matching @samp{9805*}, you would use
 
 @example
     make check-g++ RUNTESTFLAGS="old-deja.exp=9805* @var{other-options}"
 @end example
 
-This will run the @command{g++} ``old-deja'' tests in the testsuite where the filename

 The @file{*.exp} files are located in the testsuite directories of the GCC
 source, the most important ones being @file{compile.exp},
 @file{execute.exp}, @file{dg.exp} and @file{old-deja.exp}.
