Subject Re: [drlvm][jit][opt][performance] Inliner heuristics improvements: hotness and instance initializer bonuses

Hi, Bu Qi!

It's great to have escape analyzer make more through optimizations.
But the data seem to be crapped by mailer :) Can you decipher this
line? What do the numbers there mean?

scimark.monte_carlo 298.17 707.2 977.29 1.371801321 2.277627

And what's the Cycler?
