On: Chromium Blog: A New Crankshaft for V8

[natmaster]

"...performance of JavaScript property accesses, arithmetic operations, tight loops..."

Does this mean Crankshaft includes a tracing JIT like Firefox? This layman speak confuses me.

[scott_s → natmaster]

Yes, look at the list of the four main components.

[pbiggar → scott_s]

I don't think that says it uses a tracing compiler (naturally the terms are vague in this field, so I'm not certain). Their architecture looks much more like HotSpot than TraceMonkey.

[wmf → pbiggar]

Especially considering that HotSpot and V8 were designed by the same person.

[pbiggar → wmf]

I don't think this is true. Do you have a reference for that?

[codebaobab → pbiggar]

This may not be 100% literally true, but it is definitely true in spirit. (The previous poster is referring to Lars Bak, but both Hotspot and V8 are/were team efforts.) The family tree here is:

  self->hotspot->V8

But, yes, Lars is the man.

    self->hotspot-> Resilient Smalltalk Embedded Platform ->V8

[codebaobab → igouy]

OK, you got me on that one. I've been a professional Smalltalk programmer for almost 20 years and I've never heard of the Resilient Smalltalk Embedded Platform.

[igouy → codebaobab]

aka OOVM it took a novel and interesting approach - use Eclipse as the IDE to edit text files (there was a syntax for class definition) and sync bytecode with an image on a remote device through tcpip.
