* Add ability to retrieve and use the QmlContext from our generated codeLars Knoll2015-08-101-0/+1
| | | | | | | | | | | | | | Our generated code (JIT and interpreter) should operate on the QML context to retrieve QML related things. That's better than operating on 4 different temps. So this commit introduces the QML context as a temp in the code we generate for QML. The next commits will move things over to use that context with specialized runtime methods instead of using generic subscript/get calls on the different subobjects.

* Fix QQmlExpression/QQmlScriptString/QQmlBinding crashesSimon Hausmann2014-10-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | In the QQmlScriptString we store the binding id and it is an index into the runtimeFunctions array of the compilation unit. However we don't store the compilation unit and instead in QQmlBinding and QQmlExpression try to retrieve it from the cache via the context url (we have the context after all). That turns out to be not a reliable way, as sometimes the URL might slightly differ from the originally compiled cache (qrc:/// turning to qrc:/ maybe). Consequently the type is (unnecessarily) compiled again and unfortunately not _linked_, therefore the runtime functions array is empty. Another option is that when the component was created from a QByteArray, then no entry exists in the cache in the first place. This patch addresses the problem by storing a reference to the compilation unit in the QQmlContextData. That we can safely retrieve and it'll make sure the compilation unit also stays alive. In the process of that the manual reference counting was switched over to QQmlRefCount and QQmlRefPointer for QV4::CompilationUnit.

* V4: Split arguments/locals from temps.Erik Verbruggen2014-05-231-43/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a couple of reasons to split the temporaries off from the arguments and locals: Temporaries are invisible, and changes to them cannot be observed. On the other hand, arguments and locals are visible, and writes to them can be seen from other places (nested functions), or by using the arguments array. So, in practice these correspond to memory locations. (One could argue that if neither nested functions, nor eval(), nor arguments[] is used, the loads/stores are invisible too. But that's an optimization, and changing locals/arguments to temporaries can be done in a separate pass.) Because of the "volatile" nature of arguments and locals, their usage cannot be optimized. All optimizations (SSA construction, register allocation, copy elimination, etc.) work on temporaries. Being able to easily ignore all non-temporaries has the benefit that optimizations can be faster. Previously, Temps were not uniquely numbered: argument 1, local 1, and temporary 1 all had the same number and were distinguishable by their type. So, for any mapping from Temp to something else, a QHash was used. Now that Temps only hold proper temporaries, the indexes do uniquely identify them. Add to that the fact that after transforming to SSA form all temporaries are renumbered starting from 0 and without any holes in the numbering, many of those datastructures can be changed to simple vectors. That change gives a noticeable performance improvement. One implication of this change is that a number of functions that took a Temp as their argument, now need to take Temp-or-ArgLocal, so Expr. However, it turns out that there are very few places where that applies, as many of those places also need to take constants or names. However, explicitly separating memory loads/stores for arguments/locals from temporaries adds the benefit that it's now easier to do a peep-hole optimizer for those load/store operations in the future: when a load is directly preceded by a store, it can be eliminated if the value is still available in a temporary.

This replaces the earlier attempt to resolving QObject properties in fieldMemberExpression() in the codegen, but it was incomplete and now things like the following are fully resolved: var tmp = blah.somePropertyThatReturnsAQQuickItem; <-- QQuickItem property return type propagated into tmp var width = tmp.width; <-- and picked up here again to resolve the index of width instead of by name With this patch Temp gets a helper structure with a function pointer, initialized to aid the resolution of properties in Qt meta objects. This structure is propagated into the temps until it reaches the next member expression that uses the temp. Similarly QObjectType is added as IR type, next to VarType. The resolution inside the SSA type interference pass also requires passing through the QQmlEngine from the upper caller levels, in order to resolve the property type to a potential QMetaObject property.

* | Generate CallData structures directly in the instruction selectionLars Knoll2013-09-111-4/+5
|/ | | | | | | | | Like this we can hand the CallData through the runtime methods without any need to modify them. This simplifies the code in there, and should also speed them up to some degree.

* Temporarily collect a map of all functions in the engineSimon Hausmann2013-09-021-0/+1
| | | | | | | | | | | | | | | | At the moment we collect a lot of compilation units (one per binding expression!), which for long running QML accumulates and creates a horrible performance when trying to retrieve back traces. There is work in progress to reduces the number of units down to one per QML file, and then the fixed sorted QVector might proof to be a more efficient data structure for the lookups. But until that code lands, this patch proposes to use a QMap instead for the time being, that tracks all functions. This brings down the qtquickcontrols auto-test run from 2.5 minutes to just under a minute on my machine.

* The fast and the furious, register drift.Erik Verbruggen2013-08-271-13/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the register allocator for X86_64 on Linux and MacOS. The implications are: - handle as much as possible with current code with as few changes as possible - temporarily force the register allocator to spill unop/binop arguments to the stack by doing a call in the implementation (as is the current case), so no change is needed here - only have loadThis and loadConst handle registers - have any method that might need to handle registrers actually cope with them - the inline versions of binops are not generated, as they cannot cope with registers. This will change when ISel for binops is added in the next patch. This means that we are still running with the handbrakes on, but allow for full-throttle in certain/limited cases. Note about the changed test: multiplication always returns a Number (double), so the operands are passed as doubles, so __qmljs_mul will return a double. For addition this is different: because it might return a Number or a String, the operands are passed as whatever fits best. So __qmljs_add will return an int when both operands are ints. Hence the change to the tests. Change-Id: If5bd7dffca8f7de5ba45af700b9c7bb568fc74b7 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
