| | | | | | | | | | | | Be more aggressive about using sparse arrays for object literals than for regular array handling, to reduce the memory usage in this use case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transform, material, opacity and geometry changes all used to trigger full rebuilds, which meant that very little geometry could be retained between frames. For instance, a rotating spinner on top of a gridview this would cause a full rebuild where nothing is retained. This change introduces new concept to the renderer: partial rebuilding based on render order ranges. Since the render order of nodes is strictly defined by their position in the tree and nothing else, we should use that for the majority of rebuilds. When a change comes in for a node, we invalidate its batch and all batches which it has overlapping render orders with. Render order rebuilds only happen when nodes are added and removed.

When reading a property on a QObject, we'd check if the corresponding binding for the property has been initialized or not and flush (i.e. execute) the binding if necessary. As part of the V4/V8 clean-up, commit 1eb41200948ab414f1c47d93123b41c547a993df removed the StoreV8Binding instruction, which made the call for setting the this-binding-is-not-evaluated-yet bit. Nowadays we only use StoreBinding, for which this optimization was never implemented (and not needed really). Now that we have a unified JS code path, we need to set the pending binding bit and also make sure that we call flushPendingBinding for any JS side property access (accelerated or not). Also flushPendingBindingImpl had two bugs: * In an attempt of trying to find the binding to flush, it could happen that we'd try to flush a previously destroyed binding (m_mePtr is null), so the b variable would remain the first binding in the object and we'd flush the wrong one (instead of none). Added a missing check to verify that the property index matches. * Also resetting the mePtr must be done through clear(), to ensure that the pointer in bindValues in the VME is also cleared, to avoid re-enabling the same binding again in complete(); Task-number: QTBUG-36441 Change-Id: Icdb0c8fb036051fd5d6c4d33b10cd0c0ed9a9d5c Reviewed-by: Lars Knoll <lars.knoll@digia.com>

However, if a register is used at the current position for an incoming parameter, its interval has to be split after the current position. This patch adds/fixes the latter case. This fixes crypto.js on x86. The specific problem there was that the result of an operation needed a register, and chose the one from one of the incoming parameters (which then should get spilled/split). However, this interval was already split, and started exactly at that the current position. So splitting before the current position did nothing, resulting in it staying alive and using the same register as the result. So any subsequent use of would have the invalid value.
