* QV4 Engine: Remove MSVC special casingFabian Kosmale2020-12-151-15/+0
| | | | | | | | | | | This patch removes a workaround for old versions of MSVC; we should be able to rely on the standard library nowadays.

* Transform V4_ENABLE_JIT into a featureUlf Hermann2019-04-251-45/+1
| | | | | | | | | | | | | | | | This way you can enable or disable the JIT when configuring Qt. The conditions for the availability of the JIT have also been cleaned up. There is no reason anymore to artificially restrict availability on x86 and x86_64. The reason for the existence of those clauses are old problems on windows that have been fixed by now. However, on arm and arm64, we need a specialization of the cacheFlush() function for each OS to be supported. Therefore, restrict to the systems for which such a specialization exists. iOS and tvOS are technically supported and you can enable the JIT via the feature flag now. Due to Apple's policy we disable it by default, though. Change-Id: I5fe2a2bf6799b2d11b7ae7c7a85962bcbf44f919 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Fix creation of object literalsLars Knoll2018-06-041-0/+6
| | | | | | | | | | | | | | | | Our method to create object literals wasn't compliant with the ES7 spec, as we would in some cases re-order the properties. This violated the spec which required properties to be created in order, so that for-of would also iterate over them in creation order. As a nice side effect, this simplifies the code and gets a couple of test cases using computed property names to pass.

* Garbage collect identifiersLars Knoll2018-05-021-0/+1
| | | | | | | | | | | | | | | | | | | | | Implemented by storing a backpointer to the Heap object in the identifier. Since identifiers now point back to their originating String or Symbol, we can now easily mark all identifiers that are still in use and collect those that aren't. Since Identifiers are 64bit also add support for holding an array index in there. With that an identifier can describe any kind of property that can be accessed in an object. This helps speed up and simplify some code paths. To make this possible, we need to register all IdentifierHash instances with the identifier table, so that we can properly mark those identifiers.

* | garbage collect InternalClassLars Knoll2018-04-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Internal classes are now allocated and collected through the GC. As they are important to the deletion of other objects (because of the vtable pointer living inside the internal class), they need to get destroyed after regular objects have been sweeped. Achieve this by using a separate block allocator for internal class objects. Our lookups do often contain pointers to internal classes, so those need to be marked as well, so we don't accidentally collect them.
