| * Fix ABI/API symbol taggingSimon Hausmann2018-03-121-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The findclasslist.pl perl script that produces the linker version script got confused by the "struct name" that was part of a macro and thought that the class "name" in the *_p.h was supposed to be annotated with the private API tag, resulting in a "*4name*" mask in the linker script, which in turn made lots of public symbols "private" that had name in it, such as QQmlProperty::name(). Fixing the indentation works around it and conforms to coding style.

| * Fix issue with allocating huge objects in the memory managerLars Knoll2018-03-082-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We shouldn't allocate objects that are larger than the size of a standard memory segment through the chunk allocator, as this can lead to problems when freeing the segment and then re-using it again. Instead allocate a private MemorySegment for these objects, and free it when the object gets garbage collected.

| * use nullptr consistently (clang-tidy)Shawn Rutledge2018-02-263-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | From now on we prefer nullptr instead of 0 to clarify cases where we are assigning or testing a pointer rather than a numeric zero. Also, replaced cases where 0 was passed as Qt::KeyboardModifiers with Qt::NoModifier (clang-tidy replaced them with nullptr, which waas wrong, so it was just as well to make the tests more readable rather than to revert those lines).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It turns out that not using any inline property storage comes at a relatively high price in terms of memory consumption, as we always need to also create a memberData for any object. This avoids the memberData creation in quite a few cases, as we use the additional padding we have up to the 32 byte boundary given by the memory manager to store some property data. This complicates property access somewhat. To avoid performance regressions because of this, add specialized QV4::Lookup functions that optimize for properties that are inline or in the memberData struct. Change seems to be performance neutral on v8-bench on x86_64, but reduces peak memory usage when running the benchmark by around 20%.

* | Avoid stack overflows during GC runsLars Knoll2017-04-071-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | When marking very large objects, the old code could overflow the GC stack, as it would push all it's children onto the GC stack. Be more careful about this and drain the mark stack from time to time if required. Change-Id: If11ca521f405ce63b894d4e43a83b68d33a844af Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

| | | | | | | | | | | | | | | | | | | | | | Revert back to not using the incremental garbage collector for now, as it apparently doesn't play well with weak values.
