How to use Dejagnu for gcc-3.0?

How to use Dejagnu for gcc-3.0?

[Ritu Sabharwal]

  We have already installed gcc-3.0 but installed dejagnu later.
now we have problem of accessing runtest as gcc3.0 was installed first..

make check is not able to use runtest in the dejagnu1.4.3/bin
it is searching in srcdir/dejagnu/runtest

then how to solve this problem...
regards

Put dejagnu1.4.3/bin in your PATH environment variable.

Some failures are normal.  Some of the testcases in the testsuite are there
to document known compiler bugs that we haven't fixed yet.  Some of them may
be mcompiler bugs were accidentally introduced recently and haven't been fixed
yet.

The usual way to run the testsuite is to run it twice, once without your
change, and once with your change.  If the results are worse with your change,
then you know you have a problem.

There are other testsuite results posted to the gcc-testresults mailing list.
You could try comparing your results against the ones there.

We have RUNTEST set like this in Makefile and also runtest is set in 
PATH.We tried using make check to test the testcase but it gave the 
following output.
--------------------------------------------------------------------------
make check-gcc RUNTESTFLAGS="dg.exp=loop-1.c"

runtest --tool gcc dg.exp=loop-1.c)

-----------------------------------------------------------------

What is the problem,the loop-1.c file is a simple file ,also we have done 
all the things for dejagnu and gcc-3.0 installation. Now what is the 
problem,why is it showing FAIL status.something more is to be done or the 
way in which we are checking is wrong.
