* 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 JIT: tweak generated int32 to double conversion codeErik Verbruggen2014-08-131-1/+10
| | | | | | | | | | | | | | | If the target is a FP register, and the source is a memory address, do not load the int32 ourselves, but leave it to the assembler to decide what to do. On x86(_64) this is generates a single instruction, while on ARM the assembler will insert a load on its own. For the case where the target is not a FP register, use the return value register as base register for the target address. The advantage is that the address calculation is now independent of the preceding conversion, so it can fit in a different pipeline without dependencies.

* V4 JIT: fix LookupCall on ARMErik Verbruggen2014-08-121-11/+7
| | | | | | | | | | | | | | To generate a LookupCall, the register r8 was used on ARM instead of the ReturnValue register. The reason is that the ReturnValue register is also the register for the first argument. However, now that we use callee-saved registers (r8 among them), this would clobber any value stored in r8. The fix is to actually use r0 to calculate the value, because the first argument holds the lookup table, and the call is relative to that. This leaves r8 free to be used by the register allocator.

* V4: Split arguments/locals from temps.Erik Verbruggen2014-05-231-65/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Clean up object literal handling with integral indicesSimon Hausmann2014-02-241-3/+1
| | | | | | | | | | | | | | | | | | | | | * Object literals with array indices are now created with one run-time call, instead of an initial one for non-integral keys followed by sub-sequent define_builtin_property calls. * Cleaned up propert name retrieval. Instead of using a visitor, it's easier to define a virtual method on the PropertyName type. The visitor doesn't buy us much as it's not possible to recurse within property names, and this way we can use it also from the function scanner to correctly determine the number of arguments needed for object literal initalizations. * Similarly the duplicated/common name member for all property assignments has been moved into PropertyName, for convenient access without AST casts. * Removed now unused builtin_define_property/settergetter functions from IR, run-time and moth.
