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.
