* Move memory management related functionality into it's own folderLars Knoll2015-03-021-187/+0
| | | | | | | | | Start moving the memory related functionality into it's own folder. This will simplify refactoring of the GC related functionality later on. Change-Id: I70ec6f512af7a7897625afb84d914c17572b0ccd Reviewed-by: Simon Hausmann <[email protected]>
* Update copyright headersJani Heikkinen2015-02-121-7/+7
| | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Change-Id: I61120571787870c0ed17066afb31779b1e6e30e9 Reviewed-by: Iikka Eklund <[email protected]>
* Move vtable out of internalClassLars Knoll2015-01-201-8/+10
| | | | | | | | | | | | | | | | We can move the internalClass to Object later on, and such save having the internalClass on lots of Heap objects. This commit basically adds and starts making use of a new vtable pointer in Heap::Base. In addition, the construction methods in the memory manager now automatically setup the correct vtable. Removing the vtable code from InternalClass and moving it into Object will come in a separate commit Change-Id: If49e8d73c769bf65bf47fe4dbf8b9546c8019dbc Reviewed-by: Simon Hausmann <[email protected]>
* Refactor persistent valuesLars Knoll2015-01-161-6/+4
| | | | | | | | | | Use a page wise allocation mechanism for persistent values. This significantly reduces memory consumption of persistent values and also improves their performance a lot. Change-Id: I8499d2ca5bdd871e029f643ae605a94544558bb5 Reviewed-by: Simon Hausmann <[email protected]>
* Release the VM of unused heap chunksJocelyn Turcotte2014-12-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | This changes the way that available items are linked together to allow releasing chunks not containing any inUse item after being swept. Instead of putting a freed item at the top of the stack and make it link to the item previously at the top, relink all items !inUse to point to the previously visited unused item during sweeping. This allows any chunk to be released in the process while making sure that no previous or next item will link to an address in that chunk. The performance penality of relinking the list has been measured to be ~0.6% with v8-bench.js tst_QJSEngine::largeSweep. In exchange, this helps keeping the amount of chunks to sweep lower after peaks of heap allocation, even though that ability will be restrained by heap fragmentation in long running applications.
