Reduce size of LIR instruction by one word and remove dead code. · f46906d7

fschneider@chromium.org authored Apr 26, 2012

Until now we always recorded two deoptimization environments for instructions
that are marked as calls. We actually don't need two for all LIR
instructions except one (LInstanceOfKnownGlobal) where there is a lazy
deoptimization point in deferred code.

This change remove on of them and uses one virtual function instead
to make LInstanceOfKnownGlobal work as before.

Additionally, this change removes an unused predicate save_doubles_ from LIR
instructions and removes some helper functions that are used only in one place.

Eliminate redundant array bound checks (checks already performed earlier in the DT). · 93113da5

mmassi@chromium.org authored Apr 25, 2012

As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.
