https://bugs.webkit.org/show_bug.cgi?id=67133 Reviewed by Darin Adler. Source/JavaScriptCore: Add a minimum table size to the HashTraits, instead of having it hard coded. The default value remains at 64, but can now be specialized. * runtime/StructureTransitionTable.h: * wtf/HashTable.h: (WTF::HashTable::shouldShrink): (WTF::::expand): (WTF::::checkTableConsistencyExceptSize): * wtf/HashTraits.h: Source/WebCore: Specialize the HashMap used to store registered listeners on an EventTarget to have a minimum size of 32 (rather than the default 64.) It's very rare for pages to register listeners for so many different events and this cuts memory consumption in half for the common case. As an example, for a typical post on the reddit.com front page, this reduces memory used by ~700kB on 64-bit. * dom/EventTarget.h: git-svn-id: http://svn.webkit.org/repository/webkit/trunk@93990 268f45cc-cd09-0410-ab3c-d52691b4dbfc
