danno@chromium.org	57a0c6c6e3	Inline ordered relational compares of mixed double/undefined values. Allow Crankshaft to inline ordered relational comparisons (<, >, <=, >=) that have undefined arguments in addition to double value arguments (rather than calling the generic Compare stub).

fschneider@chromium.org	1e40f7ac2c	Fix a register assignment bug in typed array stores without SSE3 available. The old code used a separate HToInt32 instruction which had a wrong register constraint for the input register which caused wrong result when the stored value is used after a typed array store. (UseRegister instead of UseTempRegister) when no SSE3 is available. This change fixes it by replacing HToInt32 with the corresponding HChange instruction which has correct register contraints.

mstarzinger@chromium.org	1a356cff3e	Fix redefinition of aliased elements in arguments. 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. Setting of an element causes attributes to remain unchanged, writability to be checked and callbacks to be called. Defining of an element causes attributes to be updated and callbacks to be overridden. The same approach could be taken for properties.

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.

lrn@chromium.org	ebccde15bc	Don't preparse large files to find boundaries of lazy functions. Instead use the preparser inline to parse only the lazy function bodies. This is still disabled for small files. More measurements are needed to determine if lazy-compiling small sources is worth it.

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. This includes: * SetProperty runtime function, Delete builtin * StoreIC and KeyedStoreIC * StubCache Review URL: http://codereview.chromium.org/8417035 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@10062 ce2b1a6d-e550-0410-aec6-3dcde31c8c00	2011-11-24 15:17:04 +00:00
