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.

erik.corry@gmail.com	baf7ebd6da	Fix assert triggered in fast/regex/pcre-test-4.html We were not filtering out all the nodes that had non-ASCII characters. That has been fixed, but because of the protection against over-deep recursion when filtering it is wrong to assert that all nodes were filtered.

rossberg@chromium.org	977b602727	MIPS: Implement rudimentary module linking. Port r11336 (6dd4e844) Original commit message: 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	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).

fschneider@chromium.org	037785baaa	MIPS: Improve performance of keyed loads/stores which have a HeapNumber index. Port r11282 (bd2ab07). Patch by Daniel Kalmar. Original commit message: 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.

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.

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.

That lets Isolate's accessors be as cheap as they were before (but adds one static initializer). - Adds OS::PostSetup() used to initialize the math functions which depend on CPU features.

mstarzinger@chromium.org	5bca664574	MIPS: Improve polymorphic loads on single slots. Port r11132 (91bdad6108). Original commit message: If all property lookups for a polymorphic load actually result in the same field index under all maps, we can actually emit a monomorphic load that is guarded by a map check that verifies that the actual map is in the set of handled maps. This also allows GVN to get rid of redundant such map checks.

svenpanne@chromium.org	4cb600962f	Make setting of accessors even more atomic. Now the whole getter/setter/attributes triple gets created/set together, avoiding any hacks regarding previous values/attributes, making things a lot simpler. While doing this, an interesting problem surfaced, which has been there for a long time: After adding/changing acessors in slow mode, we could potentially fail going back to fast mode because of a failed memory allocation, signaling the need for a GC. But we have already changed the object in slow mode, so we are not idempotent and the retry would trigger a newly inserted assertion (namely, that the code obeys access restrictions). This has been solved by splitting the transformation to fast mode from the actual setting of the accessors.
