MIPS: Implement KeyedStoreICs to grow arrays on out-of-bound stores. · b098a2bd

danno@chromium.org authored Feb 14, 2012

Port r10673 (18d3af5).

Original commit message:
Supports growing non-COW JSArray by a single element if the backing store has room, and initial allocation of a backing store for the store to index zero of an empty array to kPreallocatedArrayElements elements (e.g. the [] array literal).

Enable optimization of top-level code and generate deoptimization support lazily. · 0be449d6

fschneider@chromium.org authored Feb 14, 2012

This change enables optimization of top-level and eval-code. For this to work, it adds
support for declaring global variables in optimized code.

At the same time it disables the eager generation of deoptimization support data
in the full code generator (originally introduced in
r10040). This speeds up initial compilation and saves
memory for functions that won't be optimized. It requires
recompiling the function with deoptimization
support when we decide to optimize it.

Ensure that we do a non-incremental GC before relying on weak handle callbacks. · 8a7f1568

svenpanne@chromium.org authored Feb 13, 2012

Previously, some tests failed when being run with a low GC interval. This was
caused by a switch of the GC to incremental marking mode, which in turn did not
fire any callbacks for weak global handles. Now we make sure that we run in
non-incremental mode, although via a slightly misleading GC flag.

We should probably review the uses of PerformScavenge() and gc() in our tests to
see if they actually mean "make sure our callbacks fired".
