Great news, thanks !
Looking on results I am not sure how to explain them though.
For example r325313 fixes "use after free", it should not give any performance
slowdowns or boosts. Though if I read results right, they show 23.65% slowdown
for time of linking linux kernel (http://lnt.llvm.org/db_default/v4/link/104).
I guess such variation can happen for example if bot do only single link iteration for tests,
so that final time is just a error mostly probably.
task-clock results are available for "linux-kernel" and "llvm-as-fsds" only and all other
tests has blank field. Should it mean there was no noticable difference in results ?
Also, "Graph" and "Matrix" buttons whatever they should do show errors atm.
("Nothing to graph." and "Not Found: Request requires some data arguments.").
