gcc/testsuite/README.g++

This file needs a little updating, but is pretty close.  Here are some
random last minute notes:

make check and make check-g++ aren't in FSF's gcc yet, I am planning
on getting this work into the tree some time...

> and the command

>       runtest --tool g++ --srcdir ./testsuite

> doesn't work.  I got it to work by explicitly setting CXX and CXXFLAGS
> on the command line, e.g.

> runtest --tool g++ --srcdir ./testsuite CXX=g++ CXXFLAGS=""

site.exp updated to have right CXXFLAGS and CXX, but not at the FSF yet.


  This is a collection of tests for g++, the FSF's C++ compiler. The
driver that runs the testsuite is called DejaGnu.  If you do not have
DejaGnu yet, you will need to get it (ftp://ftp.cygnus.com/pub/dejagnu).
You will need a snapshot of DejaGnu of 02/21/97 or later.  The tests
were developed and/or collected by Cygnus Support. These tests are
included "as is". If any of the tests fail, don't report a bug.  Bug
reports for DejaGnu can go to bug-dejagnu@prep.ai.mit.edu.  Discussion
and comments about this testsuite can be sent to me, at the address
below.

  Since these are part of the development source tree at Cygnus, this
tar file is supposed to be untarred so that the testsuite directory is
in the gcc source tree. Most of the time DejaGnu is run by hand using
"runtest", but as we believe in solid testing, we've integrated it
into the Makefile as a target. We normally use the testsuite by doing
a "make all; make check-g++" at the top level and building and testing
our whole tree.  If you have both the gcc testsuite and the g++
testsuite, you can check both with the "make check" command.

  DejaGnu can be run either installed, or uninstalled. Usually it gets
installed so that anyone can just run the tests without having to
configure or build DejaGnu.

  To run the tests, first change to the gcc-2.7.1 directory, then type:

	runtest --tool g++ --srcdir ./testsuite

Here's a brief explanation.

runtest         - Is the name used to invoke DejaGnu.   If DejaGnu is not
		  install this will be the relative path name for runtest.

--tool          - This tells DejaGnu which tool you are testing. It is
                  mainly used to find the testsuite directories for a
                  particular tool when several testsuites are in the
                  same directory. (like the gcc and g++ testsuites)

--srcdir        - This points to the top level of the directory
                  containing the sources of the testsuite. This is
                  ./testsuite if you are in the directory that has the
                  testsuite directory.
