--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to psturm from comment #3) > I understand the test suite cannot contemplate every single combination of > configure options. However, I would suggest that certain combinations might > be more common than others. That certainly doesn't apply to VTV, I don't know of anybody using it. > I am not a programmer, but I can run the builds with various build > parameters and report my results. Most of the 2106 failures for libstdc++ > are for "compilation failed to produce executable", so I suspect if we can > figure out why that is happening, we can dramatically reduce the scope of > what we need to look at. Looks in $target/libstdc++-v3/testsuite/libstdc++.log
