Do not ignore an empty context with extension when creating a scope object. · 8093e397

ulan@chromium.org authored Feb 02, 2012

Runtime_DebugEvaluate creates an empty context which is not correctly handled in FullCodeGenerator::ContextSlotOperandCheckExtensions because the corresponding scope indicates that it has no context.

Give uses within a loop a greater weight when doing representation inference. · 82d1f515

svenpanne@chromium.org authored Feb 01, 2012

Uses of a value are weighted by a factor of FLAG_loop_weight (default: 10) for
every loop they are in. This makes uses in inner loops "more important", which
should improve the result of the representation inference.

Break a circular include dependency. · 87ccb1d7

kmillikin@chromium.org authored Jan 27, 2012

1. heap-inl.h has a function Heap::_inline_get_heap_ that calls
Isolate::Current() defined in isolate.h, so heap-inl.h requires
isolate.h.

2. Isolate has an embedded Heap member, so isolate.h requires heap.h.

3. heap.h has inline functions functions defined that call
Heap::_inline_get_heap_, so heap.h requires heap-inl.h (!).

The upshot is that all three need to be included wherever one is.  A
simpler way is to break the cycle by moving the inlined functions in
heap.h to heap-inl.h.
