Great work - thanks for putting so much effort on this Sergey, I found
all your comments very easy to read/understand and I'm not too deep in
I'd say those results look good - especially considered the early stage
of the implementation. Basically, with invokeExact, MVT performs more or
less identical to the baseline in all benchmarks. The only exception
seems to be those multIJKTotalLoop/multIKJTotalLoop benchmarks, in
which, as you point out, something is preventing full MH compilation.
I'm sure our C2 gurus will look into that soon.
