The automated tester at
http://www.tat.physik.uni-tuebingen.de/~rguenth/gcc/monitor-summary.html
completed its first 3.5 build. I never checked 3.5, and so I'm
surprised on the numbers it got.
The obvious question is, why is 3.5 so much better than 3.4? And of
course, why is tree-ssa not better than 3.5 for C++ expression template
numeric code?
Could be attributed to changed inlining decisions as all tests have
leafify patch disabled (though I don't mention any changes here 3.4 vs 3.5).
