Re: [PATCH] libstdc++: Reduce output of 'make check'

["François Dumont" <frs.dumont@gmail.com>]

+1 for this cleanup, thanks.

Sorry to troll but I noticed another annoying recent behavior. Maybe the 
one who did it will recognize himself and will be willing to find a 
solution :-)

When I create a testsuite_files file with 1 test case I have the 
following output:

Running 
/home/fdumont/dev/gcc/git/libstdc++-v3/testsuite/libstdc++-dg/conformance.exp 
...

         === libstdc++ Summary ===

# of expected passes        6

It should be 2. There are 4 additional tests coming from 
experimental/simd folder.

I guess they are automatically added for good reasons. But it would be 
great to add those only if there is no testsuite_files.
