* Remove the old v4 and rename v4vm to v4Simon Hausmann2013-04-291-1580/+0
| | | | | | | | For archeologists v4 can still be found in the history. Otherwise it is confusing to have both engines in the tree. Change-Id: Ice05afb7013f0fe536aab6bb19114f696c58fc94 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* Evaluate bindings more intelligently during constructionAaron Kennedy2012-08-291-8/+9
| | | | | | | | | | | | | | | | | Instead of just evaluating bindings in a fixed order, and possibly having to evaluate a single binding multiple times, prior to reading a property, we check if there are any bindings "pending" on it and evaluate them then. A pending binding is one that has been assigned to the property, but not yet evaluated. To minimize side effects we only do this for "safe" bindings. A safe binding is one that has no side effects, which we currently define as not calling functions or otherwise assigning values during its evaluation. This isn't an entirely foolproof way to ensure that the evaluation has no side effects, but it should be good enough.

* Refactor singleton type registration codeChris Adams2012-08-281-5/+5
| | | | | | | | | | | Previously each singleton type was registered as an implicit separate import. This commit changes the code so that these types are treated just like any other type in the registration sense. It also ensures that singleton types are instantiated per-engine.

* Reduce memory consumption of source coordinatesMatthew Vogt2012-08-161-5/+5
| | | | | | | | | | Reduce memory consumption by storing source location coordinates as 16-bit variables (in run-time structures). Also modify qmlmin to restrict line lengths so that the column bound is not normally exceeded. Change-Id: I08605626ffbdf081b6da2aea1116bdfe24998572 Reviewed-by: Yann Bodson <yann.bodson@nokia.com>
* Add type name to singleton (module api) implementations.Glenn Watson2012-08-081-1/+1
| | | | | | | | | | | | | This change renames the previous module api implementation to singleton types. When a singleton type is registered, a type name must be provided that is used when accessing the API from QML. This makes the implementation more consistent with the rest of QML.

* Use V4 binding for non-final properties where possibleMatthew Vogt2012-07-091-3/+5
| | | | | | | | | When a property referenced in a binding is not marked as final, do not automatically abort optimization. Instead generate both V4 and V8 binidngs, and only fall back to the V8 binding if necessary at run time.

* Lazily create QMetaObjectsAaron Kennedy2012-05-241-1/+1
| | | | | | | | | | For internal QML built types, creating a metaobject each time is just wasteful. Additionally, as the property caches were always created from the intermediate QMetaObject, it was difficult to pass information directly from the compiler to the property cache.

* Fix constant folding for simple binary expressionRoberto Raggi2012-04-031-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change improves constant folding of numeric and string literals. Also, we go back generating quadruples instead of IR-tree-expressions. This is kind of needed to reduce register pressure in the V4 VM. That is, V4 has typed registers so before reusing a register we need to look at the type and eventually dispose its contents (e.g. when a QString or a QUrl is stored in the register). Unfortunately, we can't effort to have all these checks in the V4 instructions. So we change `binop' to generate literals (e.g. CONST or STRING) or a TEMP (aka a preassigned register that cannot be reused). For exmaple, the IR code generated for Rectangle { color: "b" + "l" + ("u" + "e") width: 10 + 20 + 30 } is ==================== line: 3 column: 10 L0x811ca10: t0 = string_to_color("blue"); return t0; ==================== line: 4 column: 10 L0x811ca50: return 60; Change-Id: I4d8482ddab9193d8469bda6461bfb2e5a3eeb197 Reviewed-by: Aaron Kennedy <aaron.kennedy@nokia.com>
