It was only used for Math.log, and even then only in full code and in %_MathLog. For crankshafted code, Intel already used the FP operations directly, while the ARM/MIPS ports were a bit lazy and simply called the stub. The latter directly call the C library now without any cache. It would be possible to directly generate machine code if somebody has the time, from what I've seen out in the wild it should be only about a dozen instructions.

This is just a rename change with the exception of a bug found along the way in CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the intent is to get the boilerplate object from an AllocationSite. But the wrong HObjectAccess was used. It only succeeds because it happened to be the same offset :).

The live registers are now only stored to the expression stack with the non pointer values being stored as smis (on the 32-bit platforms these values are assumed to be 31-bit max). This makes the CEntryStub entry/exit code much simpler, and there is no longer any need for a mode (debug or normal) on it. Fix a missing live register when breaking at ARM keyed load.

Object model changes ---------------------------------------- New fixed_cow_array_map is used for the elements array of a JSObject to mark it as COW. The JSObject's map and other fields are not affected. The JSObject's map still has the "fast elements" bit set. It means we can do only the receiver map check in keyed loads and the receiver and the elements map checks in keyed stores. So introducing COW arrays doesn't hurt performance of these operations. But note that the elements map check is necessary in all mutating operations because the "has fast elements" bit now means "has fast elements for reading". EnsureWritableFastElements can be used in runtime functions to perform the necessary lazy copying. Generated code changes ---------------------------------------- Generic keyed load is updated to only do the receiver map check (this could have been done earlier). FastCloneShallowArrayStub now has two modes: clone elements and use COW elements. AssertFastElements macro is added to check the elements when necessary. The custom call IC generators for Array.prototype.{push,pop} are updated to avoid going to the slow case (and patching the IC) when calling the builtin should work. COW enablement ---------------------------------------- Currently we only put shallow and simple literal arrays in the COW mode. This is done by the parser.

This adds a check to the fast case string add to ensure that the String object still have the default valueOf function. The default valueOf is sitting on a hidden prototype of String.prototype. Before using the fast case valueOf the object is checked for a local valueOf property. For slow case objects this check always reports true (the dictionary is not probed, so valueOf might be there) and for fast case objects the descriptor array is checked for the valueOf symbol (just liniar scan). After that the prototype is checked for beeing the initial value of String.prototype. If this all pass (that is the default valueOf is still in place) this result is cached on the map making the check fast the next time. This is only implemented in the optimizing compiler, as the two usages of %_IsStringWrapperSafeForDefaultValueOf is never hit by the full compiler. I will port to x64 and ARM when this has been reviewed for ia32. I will remove the performance counters prior to final commit.

This includes adding a new inline IsSpecObject method to the code generator. The old approach was somehow ineffecient since we would call both IsObject, IsUndetectable and IsFunction to determine if something was an object according to the spec. This change introduces a new macro that determines if something is an object according to the spec (and this does not include null). This change also corrects a few places where undetectable objects was not allowed even when they should be (priorly they would use only IS_SPEC_OBJECT_OR_NULL, which would return false on an undetectable object, the new IS_SPEC_OBJECT returns true on an undetectable object.
