* Simplify CompiledData::Unit serializationSimon Hausmann2016-07-151-1/+4
| | | | | | | | | | | | | | | There are currently two places where we calculate the total size of a CompiledData::Unit including all of its data, once in its calculateSize() function and then when constructing the Unit itself. This is error prone when trying to do changes to the layout, as two places need to be adjusted. Instead we can centralize the populating of the entire CompiledData::Unit header, the calculation of the various offsets as well as the entire size in one shot in a new generateHeader function. Afterwards we can allocate the final amount of memory and copy the remaining bytes across and assemble the final data structure.

| | | | | | | | We can serialize the compiled JS class data right when we collect it from the IR. That makes the assembly of the compilation a little simpler later on. Change-Id: I36d7dd2cc74241338fb1c236ce7778405066c8b8 Reviewed-by: Lars Knoll <lars.knoll@qt.io>

* Extend the QML bootstrap library by the IR buildersSimon Hausmann2014-04-231-2/+2
| | | | | | | | | | | | | This is among other things needed to fix the qml import scanner to detect dependencies from .js files correctly. The patch also fixes the use of Q_QML_EXPORT towards Q_QML_PRIVATE_EXPORT where appropriate and corrects the wrong include path for the double conversion code to actually be relative to the file it is included from. This worked by accident because of other include paths present in the build. Change-Id: I338583dad2f76300819af8ab0dae8e5724c84430 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

| | | | | | | | | | Move the string table (index and data) to the end of the compilation unit. That makes it easier to extend the string table later with new strings - for example when transitioning from JS data to an entire QML unit - because all the other offsets within the JS data remain the same.

* Clean up object literal handling with integral indicesSimon Hausmann2014-02-241-1/+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.

* Clean up property dependency data structuresSimon Hausmann2013-12-051-7/+0
| | | | | | | | | | | | | | | | As a follow-up to the previous commit, this patch cleans up the data structures used to track dependencies of QML binding expressions and functions to context and scope properties, determined at compile time. Instead of "collecting" these depending properties upfront (codegen time), we propagate the information that a property is a context or scope property into the IR at codegen time and later in the isel collect these properties and their notify signal index in a hash in the IR functions. The CompileData structure generator then can read these hashes directly when writing out the dependency information.

* Initial support for resolving meta-property access for the scope and context ↵Simon Hausmann2013-10-311-1/+9
| | | | | | | | | | | | | | | | | objects at QML compile time This avoids having to do a string lookup for ids and in the import cache at run-time, before we can do a string hash lookup in the property cache. Instead we resolve final properties in the context and scope object at compile time and look them up at run-time using their index instead. The dependencies to these properties are also tracked separately and recorded in the compiled data. This is merely the initial patch. There's a lot left to do, such as having specialized getter and setters for specific property types. Setters are missing altogether right now and will fall back to name lookup.

* Speed up id object lookupsSimon Hausmann2013-10-291-0/+1
| | | | | | | | | | | | | | | | | We can resolve lookups for objects referenced by id at QML compile time and use a run-time helper to extract the id object out of the QML context data by index instead of name. Dependencies to id objects are also tracked at compile time and registered separately before entering the generated function code. The lookup of id objects is encoded in the IR as special member lookups. Members will also then in the future be used to for property lookups in context and scope properties, as well as any other property lookups in QObjects where we can determine the meta-object.

* Beginning of a new qml parserSimon Hausmann2013-09-081-5/+6
| | | | | | | | | | | | | | The goal is to parse QML and JavaScript binding expressions/functions in one go and generate data structures that allow for the parsing to happen in a thread and the instantiation of the object tree in another thread, just reading from the generated data structures. This will replace qqmlcompiler and the VME. This new way of loading QML is currently hidden behind the QML_NEW_COMPILER=1 environment variable. There's lots of work left to fill in the gaps in object construction, Component support, Component.onComplete, error messages, etc. etc. Change-Id: I5e40643cff169f469f0b6ce151584ffee5ca5e90 Reviewed-by: Lars Knoll <lars.knoll@digia.com>
