Not linear.
Pattern matching optimization usually repeats until no further modifications are
done.
This is one way such things as constant expression elimination is achieved. Each
time a pattern is identified (and replaced by the equivalent), the cycle repeats
as that may reveal another pattern to be replaced.[ Reply to This | Parent | # ]

>> maybe the JVM also doesn't use fully simulated execution for array
initialization <<
While in theory the patents were based on what is in the Java Platform that was
new and unique, as was pointed out when Oracle tried to bring it up it is not
relevant to the trial whether Java actually practices any of the patents. The
Sun patent lawyers tried to write the claims to be as broad as possible, to
maximize the likelihood of something infringing, but as narrow as necessary to
avoid being invalidated due to prior art. What they came up with was not
necessarily an accurate representation of the invention that was made, in this
case for the Java VM.

I don't think Google's expert dropped the ball. Read the portion in the article.
Simulated execution is live in the JVM, a dress rehearsal, for a stack based
machine which means pushing and popping instructions on the stack, and the
java byte codes from the java compiler that is the input is targeted to a stack
based machine (JVM).
I find Dr. Parr to be much clearer and plainer than Dr. Mitchell and I find Dr.
Mitchell to be confusing and speaking word games.[ Reply to This | Parent | # ]

I tend to agree, although I would have focussed on the idea that simulated
execution means that you maintain state that is directly analagous to the state
of the target machine during actual execution.
Of course there are lots of creative metaphors you could use, but I'm not sure
if they tend to help or hinder.[ Reply to This | Parent | # ]
