| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | backing store https://bugs.webkit.org/show_bug.cgi?id=118914 Reviewed by Geoffrey Garen. Source/JavaScriptCore: There are two distinct actions that we're trying to optimize for: new Array(100000); and: a = []; a[100000] = 42; In the first case, the programmer has indicated that they expect this Array to be very big, so they should get a contiguous array up until some threshold, above which we perform density calculations to see if it is indeed dense enough to warrant being contiguous. In the second case, the programmer hasn't indicated anything about the size of the Array, so we should be more conservative and assume it should be sparse until we've proven otherwise. Currently both of those cases are handled by MIN_SPARSE_ARRAY_INDEX. We should distinguish between them for the purposes of not over-allocating large backing stores like we see on http://www.peekanalytics.com/burgerjoints/ The way that we'll do this is to keep the MIN_SPARSE_ARRAY_INDEX for the first case, and introduce a new heuristic for the second case. If we are putting to an index above a certain threshold (say, 1000) and it is beyond the length of the array, then we will use a sparse map instead. So for example, in the second case above the empty array has a blank indexing type and a length of 0. We put-by-val to an index > 1000 and > a.length, so we'll use a sparse map. This fix is ~800x speedup on the accompanying regression test :-o * runtime/ArrayConventions.h: (JSC::indexIsSufficientlyBeyondLengthForSparseMap): * runtime/JSObject.cpp: (JSC::JSObject::putByIndexBeyondVectorLengthWithoutAttributes): (JSC::JSObject::putByIndexBeyondVectorLengthWithArrayStorage): (JSC::JSObject::putByIndexBeyondVectorLength): (JSC::JSObject::putDirectIndexBeyondVectorLengthWithArrayStorage): git-svn-id: http://svn.webkit.org/repository/webkit/trunk@153374 268f45cc-cd09-0410-ab3c-d52691b4dbfc Change-Id: I1c29992d6e09c9d523a8093e76e3848a9581ce45 Reviewed-by: Jocelyn Turcotte <jocelyn.turcotte@digia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support Windows XP we must avoid using the 64bit variants of the atomicIncrement/atomicDecrement operations which are only supported from Windows 2003 and up. This patch rolls back the minimum Win32 API version to WinNT 5.1 (32bit WinXP), and adds a new flag to indicate the support of 64bit atomics. The new flag is now also used to support MIPS and other architectures without 64bit intrinsics, instead of hacking in poor support. This also extends the atomic operations to sparc64 which was previously skipped because it did not work with __exchange_and_add.

Due to the way that numCacheableSlots is currently calculated, checking an object's prototype for enumerable properties causes us not to cache any properties at all. We should only cache properties on the object itself since we currently don't take advantage of any sort of name caching for properties in the prototype chain.
