Hi,
There are at least three problems that are still there. They might be
connected, or not.
(I will tell you how to reproduce these at the end)
I just built a new JVM:
openjdk version 1.7.0-internal
OpenJDK Runtime Environment (build
Hi,
Just to clarify, my builds are against the current patchset in the MLVM
repository, so that might explain why you're not seeing these problems.
Cheers

I know that. That's why we need to find out where the problem is (some hints
below). Can
Well, on my linux box with a JDK built this morning I don't see any of
these problems actually. (However, there are things on my master that
only works with the mlvm patches. Type conversions specifically.)
Problem 3 also seems to not be there - you would notice if it were since
it's also a total

(like John's meth.jar)?
I just posted it with the javadoc:
Actually now that I look at it, this isn't all that solid performance.
It's just *slightly* faster than using JRuby's inline cache, which
almost never inlines...
Inline cache only, via CachingCallSite.

About 0-9.

That's the spirit! We can do it!

I've got the bimorphic method handle inline working. I was doing something
stupid at the beginning which is why it wasn't as easy as I expected to be and
then I encountered a stupid API which wasted a little more time. I was able to
leverage the existing invokedynamic call site cache code

Oh my goodness...I just realized an obvious missing API...is there still time?!
SwitchPoint has no way to query if it has been invalidated!
Is this by design? I would like to use this as both a call site guard
and as a queryable trigger...to know whether I can go forward with the
faster
Ok, onward with perf exploration, folks!
I'm running with mostly-current MLVM, with John's temporary reversion
of GWT to the older non-ricochet logic.
As reported before, fib has improved with the reversion, but it's
only marginally faster than JRuby's inline caching logic and easily

Take a look at the way I use SwitchPoints in Seph. The api you're
looking for is already there:
SwitchPoint x = new SwitchPoint();

Well, lacking a method, it's actually probably the most
straightforward one :-) Ola wins gazillion points for
resourcefulness.
Actually, it was Remi who came up with this gem when we discussed adding
an isInvalid() method on SwitchPoint.
