svenpanne@chromium.org	cb4840c0e5	Inline simple getter calls. Currently only simple getter calls are handled (i.e. no calls in count operations or compound assignments), and deoptimization in the getter is not handled at all. Because of the latter, we temporarily hide this feature behind a new flag --inline-accessors, which is false by default.

verwaest@chromium.org	d7a5b7d5e2	Separating transitions from descriptors. In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array. The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly. Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.

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.

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.

fschneider@chromium.org	71702e1da3	Improve performance of keyed loads/stores which have a HeapNumber index. Some GWT compiled code results in array access that has a heap number (e.g. -0) as an index. Until now this would result in a generic IC. For example: a[-0] === a[0] or a[0.25 * 4] === a[1] This change detects heap numbers that are representable as a smi and converts them. As a result we can still use the fast keyed monomorphic ICs. Optimized code already handles keyed access with a double-key efficiently. As a result the frame rate on the reported benchmark improves by roughly 2x.

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.

svenpanne@chromium.org	c644c4e811	Ensure that generated code for object literals will call Runtime_DefineOrRedefineAccessorProperty only once per accessor property. To do this, we collect all accessor properties in a first pass and emit code for defining those properties afterwards in a second pass. As a finger exercise, the table used for collecting accessors has a (subset of an) STL-like iterator interface, including STL-like names and operators. Although C++ is quite verbose here (as usual, but partly this is caused by our current slightly clumsy classes/templates), things work out quite nicely and it cleans up some confusion, e.g. a table entry is not an iterator etc. Everything compiles into very efficient code, e.g. the loop condition 'it != accessor_table.end()' compiles into a single 'testl' instruction on ia32. +1 for using standard APIs!

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.

For this enum-cache was extended to store property indices in a separate array (see handles.cc). New hydrogen instructions: - HForInPrepareMap: checks for-in fast case preconditions and returns map that contains enum-cache; - HForInCacheArray: extracts enum-cache array from the map; - HCheckMapValue: map check with HValue map instead of immediate; - HLoadFieldByIndex: load fast property by it's index, positive indexes denote in-object properties, negative - out of object properties; Changed hydrogen instructions: - HLoadKeyedFastElement: added hole check suppression for loads from internal FixedArrays that are knows to have no holes inside.

One has to look at the actual contents of the descriptor entry then, but this breaks down sometimes when the lookup is being done with a NULL holder.

In addition, a new specialized compare ic known objects cache is created. The reason for the cache is that we need to have access to the stub code from the roots; if we do not, the GC will collect the stub. In this specialized case we use the map pointer as key in the cache, and we always do a lookup before generating code. Actually hitting something in the cache will happen very rarely, but we could potentially overwrite an existing stub, which again will lead to the GC collecting this old stub (even if it is referenced from other code objects) Review URL: http://codereview.chromium.org/8520006 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@10216 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2011-12-08 17:17:21 +00:00

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.

mstarzinger@chromium.org	7e7d4dfd64	Implement crankshaft support for nested object literals. This generates optimized code for deep-copying of nested object literal boilerplates which are statically known. Most of the boilerplates have already been generated at crankshaft time, so this optimization should kick in for virtually every object literal. Only nested object literal graphs up to a certain depth and containing up to a certain total number of properties are considered for this optimization. This will prevent explosion of code size due to large object literals (e.g. eval on JSON). Improves splay performance because object literals are created often.

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.

svenpanne@chromium.org	cf63503cad	Unify the handling of comparinsons against null and undefined. Although this patch is not small, most parts of it are rather mechanical: * First of all, the concept of a 'nil-like' value is introduced, which can be null or undefined. They are treated symmetrically regarding comparisons, so it makes sense to handle them in a uniform manner. It is a mystery why JavaScript defines two of those beasts, when even one is a design wart... * Extended and renamed a few things which now handle undefined in addition to null. * Made the parts of the full code generator and the hydrogen generation which deal with comparisons a bit more similar regarding their handling of special cases. * Refactored the syntactical detection of special cases for comparisons, hopefully making them a bit more readable and less copy-n-paste-oriented. Things like this should really be a one-liner in any sane programming language... :-P * Cut down the length of the argument lists of a few functions to something less insane, making them more easily understandable locally. This involves minor code duplication, but this was a good tradeoff and can be remedied later if necessary. * Replaced some boolean arguments with more readable enums. * Fixed a TODO: Values which are definitely a Smi or unboxed can never be equal to null or undefined.

svenpanne@chromium.org	8c744768e2	Nuke CompareToNull AST node. The Great Master Plan is to move the recognition of special cases for comparisons further down the compilation pipeline where more information is available. This is a first step into this direction: The special handling of equality comparisons involving null is pushed from the parser to the code generators, removing the need for a special AST node. (There are rumors from usually well-informed sources that this node type is actually a relic of ancient crankshaft days...) The next steps will be the unification of null/undefined handling and pushing the special case handling in crankshaft even further down the pipeline, enabling the recognition of cases like "var foo=null; if (foo === bar) ...", but these will be in separate CLs.

Changing our builtin JavaScript code slightly, we can make sure that we never see internal objects as arguments for ToBoolean at runtime. Removing that case from the stub generator and crankshaft makes things a lot easier. Heap numbers can never be undetectable (only strings and spec objects can), so we can leave out a useless test. Try to re-use a non-null register value when returning 'true' in some cases. Removed special handling of the 'handle all' case, it will very probably never happen in real code and only makes things more complicated.

svenpanne@chromium.org	e48ec1c4bd	Use type info for the ToBoolean translation in crankshaft. To do this, the Branch instruction needs to carry around a temporary register, but only when the crankshafted code will make a map access. When the crankshafted code sees an object of a type it hasn't encountered before, it will always trigger a deopt. Another option in theses cases would be calling a ToBooleanStub which can handle all types, but then one has to be careful to not trigger a GC (which is currently a bit tricky to achieve). Const-corrected ToBoolean::Types. Moved the NeedsMap logic into ToBoolean::Types itself, where it belongs. This patch improves a lot of benchmarks, crypto-orig even by 16.7%, but slows down others. The slowdown has to be investigated, but I'd like to get this patch out first to fix the flakiness problems we currently have due to the previous crankshafted ToBoolean.

svenpanne@chromium.org	c71cf782e8	Drastically reduce the transitive dependencies of jsregexp.h, making it (almost) architecture-independent. jsregexp.h is itself included transitively quite a lot, and by getting rid of 19 of its dependencies (which even included things like src/cpu.h, the various assemblers, etc.), the recompilation behaviour is a bit less funny than it was.

danno@chromium.org	07def3cb1e	Unify handling of element IC stubs. In the process, add shared stubs for DictionaryValue lookups that are handled in the same way as fast elements and external array elements. Includes code for MIPS, which compiles and run polymorph-arrays.js successfully.

svenpanne@chromium.org	c8618923ec	Removed useless implementations of GetName and Print for code stubs, the common super-class handles the most common case already.
