mvstanton@chromium.org	3cf157b43b	Inline zero argument array constructor. ... patch from issue 54583003 (dependent code). Zero arguments - very easy 1 argument - three special cases: a) If length is a constant in valid array length range, no need to check it at runtime. b) respect DoNotInline feedback on the AllocationSite for cases that the argument is not a smi or is an integer with a length that should create a dictionary. c) if kind feedback is non-holey, and length is non-constant, we'd have to generate a lot of code to be correct. Don't inline this case. N arguments - one special case: a) If a deopt ever occurs because an input argument isn't compatible with the elements kind, then set the DoNotInline flag.

rossberg@chromium.org	cec8383cff	Provide private symbols through internal APIs ... Adds a notion of private symbols, mainly intended for internal use, especially, self-hosting of built-in types that would otherwise require new C++ classes. On the JS side (i.e., in built-ins), private properties can be created and accessed through a set of macros: NEW_PRIVATE(print_name) HAS_PRIVATE(obj, sym) GET_PRIVATE(obj, sym) SET_PRIVATE(obj, sym, val) DELETE_PRIVATE(obj, sym) In the V8 API, they are accessible via a new class Private, and respective HasPrivate/Get/Private/SetPrivate/DeletePrivate methods on calss Object. These APIs are designed and restricted such that their implementation can later be replaced by whatever ES7+ will officially provide.

mvstanton@chromium.org	cec8548d0e	Correct handling of arrays with callbacks in the prototype chain. ... Our generic KeyedStoreIC doesn't handle the case when a callback is set on array elements in the prototype chain of the object, nor do we recognize that we need to avoid the monomorphic case if these callbacks exist. This CL addresses the issue by looking for dictionary elements in the prototype chain on IC misses and crankshaft element store instructions. When found, the generic IC is used. The generic IC is changed to go to the runtime in this case too. In general, keyed loads are immune from this problem because they won't return the hole: discovery of the hole goes to the runtime where the callback will be found in the prototype chain. Double array loads in crankshaft can return the hole but only if the prototype chain is unaltered (we will catch such alterations). Includes the following patch as well (already reviewed by bmeurer): Performance regression found in test regress-2185-2.js. The problem was that the bailout method for TransitionAndStoreStub was not performing the appropriate transition.

svenpanne@chromium.org	f0305bd83e	Instance-type-related fixes and cleanup. ... Things got quite a bit out of sync (don't we all love copy-n-paste?): * TypeToString didn't handle SLICED_STRING_TYPE, SLICED_ASCII_STRING_TYPE, FIXED_DOUBLE_ARRAY_TYPE, JS_FUNCTION_PROXY_TYPE and JS_DATE_TYPE. * INSTANCE_TYPE_LIST was missing entries for SLICED_ASCII_STRING_TYPE, JS_SET_TYPE, and JS_MAP_TYPE. To improve this maintenance nightmare a little bit, the missing instance types were added to the INSTANCE_TYPE_LIST macro and this list is now used via our beloved 2nd order macro technique in TypeToString. As a side-effect, the strings returned by TypeToString have a "_TYPE" suffix now, but this doesn't really matter and is a small price to pay for consistency. Removed INVALID_TYPE on the way, it had no real use.

loislo@chromium.org	d2c443b774	Extract hardcoded error strings into a single place and replace them with enum. ... I'd like to propagate bailout reason to cpu profiler. So I need to save it into heap object SharedFunctionInfo. But: 1) all bailout reason strings spread across all the sources. 2) they are native strings and if I convert them into String then I may have a performance issue. 3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer. Also I think it would be nice to have error strings collected in one place. In that case we will get additional benefits: It allows us to keep this set of messages under control. It gives us a chance to internationalize them. It slightly reduces the binary footprint. From the other hand the developers have to add new strings into that enum.

rossberg@chromium.org	5c93b18eb2	ES6 symbols: Allow symbols as property names ... Since symbols and strings share a common representation, most of this change is about consistently replacing 'String' with 'Name' in all places where property names are expected. In particular, no new logic at all is necessary for maps, property dictionaries, or transitions. :) The only places where an actual case distinction is needed have to do with generated type checks, and with conversions of names to strings (especially in logger and profiler). Left in some TODOs wrt to the API: interceptors and native getters don't accept symbols as property names yet, because that would require extending the external v8.h.

rossberg@chromium.org	090d09d685	ES6 symbols: Implement Symbol intrinsic and basic functionality ... - Add --harmony-symbols flag. - Add Symbol constructor; allow symbols as (unreplaced) return value from constructors. - Introduce %CreateSymbol and %_IsSymbol natives and respective instructions. - Extend 'typeof' code generation to handle symbols. - Extend CompareIC with a UNIQUE_NAMES state that (uniformly) handles internalized strings and symbols. - Property lookup delegates to SymbolDelegate object for symbols, which only carries the toString method. - Extend Object.prototype.toString to recognise symbols. Per the current draft spec, symbols are actually pseudo objects that are frozen with a null prototype and only one property (toString). For simplicity, we do not treat them as proper objects for now, although typeof will return "object". Only property access works as if they were (frozen) objects (via the internal delegate object).

rossberg@chromium.org	764e1a0fcf	ES6 symbols: Introduce Symbol class, along with abstract Name class ... The new instance type 'Symbol' represents ES6 symbols (a.k.a. private/unique names). Currently, symbols are simple data objects that only carry a hash code, random-generated upon allocation. The new type 'Name' now serves as the common super class for strings and symbols, and is supposed to represent property names. We will eventually migrate APIs from String to Name for the standard key type. Strings and symbols share the same hash field representation, via the Name class. This way, we should be able to use the same code paths for symbols and internalized strings in most cases. Also, Symbol's instance type code is allocated adjacent to internalized string codes in the enum, allowing a simple range check for the common case.

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders. The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).
