alexeif@chromium.org	31a0d0257c	Serialize edge counts instead of indexes in heap snapshot. The serialized node structure currently holds an index of its first containment edge in the edges array. The index can be quite big (up to 7 digits for large snapshots). The patch changes the serialization format to pass node containment edge count instead.

rossberg@chromium.org	e4c472a7af	Implement correct checking for inherited readonliness on assignment. Removes 6 out of 8 of our remaining unintentional failures on test262. Also fixes treatment of inherited setters added after the fact. Specifically: - In the runtime, when looking for setter callbacks in the prototype chain, also look for read-only properties. If one is found, reject (exception in strict mode). If a proxy is found, invoke proper trap. Note: this folds in the CanPut function from the spec and avoids an extra lookup over the prototype chain. - In generated code for stores, insert a test for the maps from the prototype chain, but only up to the object where the property already exists (which may be the object itself). In Hydrogen, if the found property is read-only or not cacheable (e.g. a proxy), bail out; in a stub, generate an unconditional miss (to get an exception in strict mode). - Add test cases and adapt existing test expectations.

svenpanne@chromium.org	ff216c9cea	Re-land: Use map transitions when defining accessor properties. This is basically r11496, with the following changes: * Set back pointers in maps (cherry-picked from r11528) * Fixed size calculation in CopyInsert, as proposed by mstarzinger/rossberg * DefineFastAccessor uses GetCallbackObject instead of GetValue (for __proto__) * Put the code under a new flag, which is disabled by default * Cut down the corresponding regression test * Adapted bootup memory test, we actually only need a bit more memory on 64bit without snapshots, which can easily explained by more live maps lying around. Note that the snapshot variants are back to their previous limits. Next steps: Investigate any performance degradationswith the flag enabled, and finally remove the flag when things are OK. Furthermore, GetCallbackObject should be merged into GetValue, the distinction is confusing and error-prone.

svenpanne@chromium.org	065cc14449	Use map transitions when defining accessor properties. AccessorPairs can now contain map transitions, which is similar to our current handling of CONSTANT_FUNCTION/CONSTANT_TRANSITION, but generalized to a pair for holding info about the getter and the setter. This way we can achieve map sharing for objects with accessor properties, which is a prerequisite for making them fast via inlining. We fall back to the previous way of handling accessor properties when sharing is not possible or we don't handle a special case. Note: When an exisiting accessor property is redefined we could in principle move the AccessorPair out of the descriptor into the object itself (again just like the way we do something similar for CONSTANT_FUNCTION/CONSTANT_TRANSITION), but this would require a new property kind for holding a pair of values. Perhaps we can implement this later, but for now this hopefully rare case is handled like before, losing map sharing and potentially creating more maps than strictly necessary.

rossberg@chromium.org	ab26fb6b21	Implement rudimentary module linking. Constructs the (generally cyclic) graph of module instance objects and populates their exports. Any exports other than nested modules are currently set to 'undefined' (but already present as properties). Details: - Added new type JSModule for instance objects: a JSObject carrying a context. - Statically allocate instance objects for all module literals (in parser 8-}). - Extend interfaces to record and unify concrete instance objects, and to support iteration over members. - Introduce new runtime function for pushing module contexts. - Generate code for allocating, initializing, and setting module contexts, and for populating instance objects from module literals. Currently, all non-module exports are still initialized with 'undefined'. - Module aliases are resolved statically, so no special code is required. - Make sure that code containing module constructs is never optimized (macrofy AST node construction flag setting while we're at it). - Add test case checking linkage.

rossberg@chromium.org	62945585fd	Implement ES5 erratum: global declarations shadow inherited properties. I also discovered that our treatment of const declarations is inconsistent when inside a global eval under 'with' (i.e., when created by DeclareContextSlots). That is, var x; eval("const x = 9") and var x; eval("with({}) const x = 9") differ (the former assigns 9, the latter throws). This appears to be an oversight from earlier changes to our const semantics (the latter shouldn't throw either). Fixing this is a separate issue, though (and one that doesn't seem quite worthwhile).

erikcorry	f14b93a508	Regexp: Improve the speed that we scan for an initial point where a non-anchored regexp can match by using a Boyer-Moore-like table. This is done by identifying non-greedy non-capturing loops in the nodes that eat any character one at a time. For example in the middle of the regexp /foo[\s\S]*?bar/ we find such a loop. There is also such a loop implicitly inserted at the start of any non-anchored regexp. When we have found such a loop we look ahead in the nodes to find the set of characters that can come at given distances. For example for the regexp /.?foo/ we know that there are at least 3 characters ahead of us, and the sets of characters that can occur are [any, [f, o], [o]]. We find a range in the lookahead info where the set of characters is reasonably constrained. In our example this is from index 1 to 2 (0 is not constrained). We can now look 3 characters ahead and if we don't find one of [f, o] (the union of [f, o] and [o]) then we can skip forwards by the range size (in this case 2). For Unicode input strings we do the same, but modulo 128. We also look at the first string fed to the regexp and use that to get a hint of the character frequencies in the inputs. This affects the assessment of whether the set of characters is 'reasonably constrained'. We still have the old lookahead mechanism, which uses a wide load of multiple characters followed by a mask and compare to determine whether a match is possible at this point.

erik.corry@gmail.com	f00631b710	Reduce initial boot-up memory use. This is an other attempt at what http://codereview.chromium.org/9179012 was trying to achieve. This time I am going for 80% of the benefit with around 5% of the complexity. It works by reducing the size of the first page in each space. Unlike the previous change there is no attempt to grow pages, we just allocate more full-sized pages when we need more memory. For this reason the first pages are not quite as small (compare http://codereview.chromium.org/9179012/diff/1/src/snapshot.h with the changes in spaces.cc in this cl): We want to be able to do a little bit of allocation before we have to add a full-sized page to the space.

svenpanne@chromium.org	1729e3c0dd	Make the runtime entry for setting/changing accessors "atomic". Previously, there were 1 or 2 calls to the runtime when accessors were changed or set. This doesn't really work well with property attributes, leading to some hacks and complicates things even further when trying to share maps in presence of accessors. Therefore, the runtime entry now takes the full triple (getter, setter, attributes), where the getter and/or the setter can be null in case they shouldn't be changed. For now, we do basically the same on the native side as we did before on the JavaScript side, but this will change in future CLs, the current CL is already large enough. Note that object literals with a getter and a setter for the same property still do 2 calls, but this is a little bit more tricky to fix and will be handled in a separate CL.

This refactors the way we (re)define elements to perform normalization and attribute updating at a much deeper level, thereby removing some bogus special cases in upper runtime layers. Most element setters take an indicator flag that distinguishes between setting and defining.

danno@chromium.org	bd79e299e5	Uniformly handle 'undefined' store to Float64Array and Float32Array. Previous behavior diverged in ICs and Crankshaft. When storing to a Float32Array or Float64Array, the ICs treated undefined as zero while Crankshaft treated it as NaN.

svenpanne@chromium.org	8a7f1568c4	Ensure that we do a non-incremental GC before relying on weak handle callbacks. Previously, some tests failed when being run with a low GC interval. This was caused by a switch of the GC to incremental marking mode, which in turn did not fire any callbacks for weak global handles. Now we make sure that we run in non-incremental mode, although via a slightly misleading GC flag. We should probably review the uses of PerformScavenge() and gc() in our tests to see if they actually mean "make sure our callbacks fired".

erik.corry@gmail.com	e2f2c77e6f	Be more willing to expand old space when evacuating new space at the end of a mark-sweep. We have a soft limit on old space size, which is designed to trigger an old-space collection when we hit it. Unfortunately although the soft limit had already triggered an old space collection, the soft limit was preventing objects from new space from being promoted. For every promotion candidate we were checking 3 different ways to allocate in old space before giving up and putting the object in the other semispace. This change allows the promoted objects to go to old space and also makes us more eager to sweep a page before trying other ways to find space for an object.

keuchel@chromium.org	e26093f3d8	Make let/const outside of the extended mode early errors (under harmony flag). The ES.next drafts require that source code that matches the productions for let and const bindings outside the extended mode trigger early syntax errors. This CL adapts the parser / preparser accordingly under the harmony scoping flag. Summary: * Harmony scoping flag not set: Old semantics allowing const in classic mode with function level scope. Const binding in strict mode and let bindings in classic and strict mode trigger early syntax errors. * Harmony scoping is set: Use new harmony const and let in extended mode and old const in classic mode. This is to preserve compatibility with current web pages that already use non-standard implementations of const. An early syntax error is thrown on const in strict mode and on let in classic and strict mode.

keuchel@chromium.org	cbf08248f7	Make the parser track the language mode instead of keeping its own harmony flag. So far the parser had its own harmony flag to disable the harmony scoping feature when parsing native functions. With the introduction of the extended language mode this becomes unnecessary because native functions will never enter the extended mode. The parser can thus track FLAG_harmony_scoping and the language mode of the current scope to see if harmony features are allowed. The scanner and preparser have to keep their flag, because they can't use FLAG_harmony_scoping as it is not available for the preparser-process executable.

keuchel@chromium.org	1e9a7267ab	Introduce extended mode. This CL introduces a third mode next to the non-strict (henceforth called 'classic mode') and 'strict mode' which is called 'extended mode' as in the current ES.next specification drafts. The extended mode is based on the 'strict mode' and adds new functionality to it. This means that most of the semantics of these two modes coincide. The 'extended mode' is entered instead of the 'strict mode' during parsing when using the 'strict mode' directive "use strict" and when the the harmony-scoping flag is active. This should be changed once it is fully specified how the 'extended mode' is entered. This change introduces a new 3 valued enum LanguageMode (see globals.h) corresponding to the modes which is mostly used by the frontend code. This includes the following components: * (Pre)Parser * Compiler * SharedFunctionInfo, Scope and ScopeInfo * runtime functions: StoreContextSlot, ResolvePossiblyDirectEval, InitializeVarGlobal, DeclareGlobals The old enum StrictModeFlag is still used in the backend when the distinction between the 'strict mode' and the 'extended mode' does not matter.

fschneider@chromium.org	8480569467	Fix lazy deoptimization at HInvokeFunction and enable target-recording call-function stub. Changes the way we do lazy deoptimization: 1. For side-effect instructions, we insert the lazy-deopt call at the following LLazyBailout instruction. CALL GAP LAZY-BAILOUT ==> lazy-deopt-call 2. For other instructions (StackCheck) we insert it right after the instruction since the deopt targets an earlier deoptimization environment. STACK-CHECK GAP ==> lazy-deopt-call The pc of the lazy-deopt call that will be patched in is recorded in the deoptimization input data. Each Lithium instruction can have 0..n safepoints. All safepoints get the deoptimization index of the associated LAZY-BAILOUT instruction. On lazy deoptimization we use the return-pc to find the safepoint. The safepoint tells us the deoptimization index, which in turn finds us the PC where to insert the lazy-deopt-call. Additional changes: * RegExpLiteral marked it as having side-effects so that it gets an explicitlazy-bailout instruction (instead of treating it specially like stack-checks) * Enable target recording CallFunctionStub to achieve more inlining on optimized code.

keuchel@chromium.org	08c9629f80	Static resolution of outer variables in eval code. So far free variables references in eval code are not statically resolved. For example in function foo() { var x = 1; eval("y = x"); } the variable x will get mode DYNAMIC and y will get mode DYNAMIC_GLOBAL, i.e. free variable references trigger dynamic lookups with a fast case handling for global variables. The CL introduces static resolution of free variables references in eval code. If possible variable references are resolved to bindings belonging to outer scopes of the eval call site. This is achieved by deserializing the outer scope chain using Scope::DeserializeScopeChain prior to parsing the eval code similar to lazy parsing of functions. The existing code for variable resolution is used, however resolution starts at the first outer unresolved scope instead of always starting at the root of the scope tree. This is a prerequisite for statically checking validity of assignments in the extended code as specified by the current ES.next draft which will be introduced by a subsequent CL. More specifically section 11.13 of revision 4 of the ES.next draft reads: * It is a Syntax Error if the AssignmentExpression is contained in extended code and the LeftHandSideExpression is an Identifier that does not statically resolve to a declarative environment record binding or if the resolved binding is an immutable binding.

mstarzinger@chromium.org	e24c612a5e	Fix setting array length to be ES5 conform. This also refactors the way we set the length of an arrays' backing store to use the new elements accessor interface. The actual fix is in DictionaryElementsAccessor::SetLengthWithoutNormalize() where we first search for non-deletable elements according to ES5 section 15.4.5.2 specifications. Snippet from the specification: Attempting to set the length property of an Array object to a value that is numerically less than or equal to the largest numeric property name of an existing array indexed non-deletable property of the array will result in the length being set to a numeric value that is one greater than that largest numeric property name.

svenpanne@chromium.org	140ae348d2	Recognize special comparisons via pattern matching on the hydrogen graph, 2nd attempt. This time, we initially leave the HTypeof instruction in the Hydrogen graph, even for the special cases. We later try to remove this instruction (and any HConstant) in the canonicalization pass, if possible. Always removing the HTypeof during the initial graph construction is wrong if e.g. it is used in an HSimulate. The removals can be generalized a bit, but this will happen in a separate CL.
