* Get rid of qv4qmlextensionsLars Knoll2015-06-151-2/+0
| | | | | | | | It only contained the proto for the value type wrapper. Instead just create it lazily, but reserve space on the js stack for it. Change-Id: I2301549b6dc4007bd5ac848e1dca25aafd583c4a Reviewed-by: Simon Hausmann <simon.hausmann@theqtcompany.com>

* Basic support for typed arraysLars Knoll2014-10-291-0/+2
| | | | | | | | | | | | | | | This implements most of the spec required for the Khronos typed array specification. It tries to follow ECMAScript 6 as closely as possible, but currently only implements a subset of the ECMAScript 6 specification. Addes a test script in tests/manual/v4 to test our implementation.

* Extend the QML bootstrap library by the IR buildersSimon Hausmann2014-04-231-7/+15
| | | | | | | | | | | | | 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>

* Rename some filesLars Knoll2014-01-311-1/+1
| | | | | | | | | | | | Rename qv4value_def_p.h -> qv4value_p.h and qv4value_p.h to qv4value_inl_p.h. It makes more sense to have the class definition in the file that is named after the class and move the inline methods into a _inl file. Doing this now, as I expect we'll be needing a few more _inl files soon. Change-Id: Ib59e9380e9e976254c6b4369574157f39b1b5f51 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Speed up stack trace generation for the JITSimon Hausmann2013-10-161-2/+0
| | | | | | | | | | | | | | It turns out that in QML it is not unusual that during early binding evaluations due to the undefined order, the evaluation tries to look up properties in objects that aren't initialized yet and thus exceptions are thrown. Eeach thrown exception saves a stack trace, which is expensive to generate when using the JIT, as it does full stack unwinding. This patch implements a more light-weight approach by storing the instruction pointer in the context before leaving JIT generated code.

* Change v4 exceptions to use the common C++ ABIs foreign exceptionsSimon Hausmann2013-10-031-6/+5
| | | | | | | | | | | | | | | | | | | On platforms where we use the common C++ ABI, throw the exception not using a dummy C++ exception structure and the throw keyboard, but instead use the lower-level _Unwind_RaiseException to throw a foreign exception. It is caught with the existing "catch (...)" and re-throw is implemented similarly, by grabbing the current exception from the globals (a standardized data structure) and re-throwing it. On platforms such as ARM that lack hooks for supplying our unwind tables to the system run-time, this patch will make it possible to link the unwinder statically into libQtQml (libgcc or libunwind) and thus force it to use our unwind tables, because throwing or re-throwing will always go through our statically linked code through direct calls to _Unwind_RaiseException (instead of libstdc++).
