By creating the boilerplate only on the second instantiation we cannot propagate back the elements transitions early enough. The resulting literals would change the initial ElementsKind one step too late and already pollute ICs that went to monomorphic state. - Disable lazy AllocationSites for literals containing arrays - Introduce new ComplexLiteral class to share code between ObjectLiteral and ArrayLiteral - RegexpLiteral now no longer needs a depth_ field Bug: v8:6517, v8:6519, v8:6211 Change-Id: Ia88d1878954e8895c3d00a7dda8d71e95bba005c Reviewed-on: https://chromium-review.googlesource.com/563305Reviewed-by: Adam Klein <adamk@chromium.org> Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> Reviewed-by: Benedikt Meurer <bmeurer@chromium.org> Commit-Queue: Camillo Bruni <cbruni@chromium.org> Cr-Commit-Position: refs/heads/master@{#46603}

Commit 26c00f4a improved the names of most FAST_* elements kinds in the enum. This patch updates the matching Has*Elements and Is*ElementsKind method names accordingly. - HasFastSmiElements => HasSmiElements - IsFastSmiElementsKind => IsSmiElementsKind - HasFastObjectElements => HasObjectElements - IsFastObjectElementsKind => IsObjectElementsKind - HasFastSmiOrObjectElements => HasSmiOrObjectElements - IsFastSmiOrObjectElementsKind => IsSmiOrObjectElementsKind - HasFastDoubleElements => HasDoubleElements - IsFastDoubleElementsKind => IsDoubleElementsKind - HasFastHoleyElements => HasHoleyElements - IsFastHoleyElementsKind => IsHoleyElementsKind Additionally, FastHoleyElementsUsage is renamed to HoleyElementsUsage.

This mostly reverts commit c503b805 but fixes an issue where literals would always be pretenured on first instantiation. As a cleanup we pass in a PretenureFlag instead of using the FeedbackVector as indicator.

Storing the boilerplate on the first run leads to memory ovehead for code that is run only once. Hence we directly return the creating literal on the first run and only start creating copies from the second run on.

With this CL we reduce the difference between directly using a null prototype in a literal or using Object.create(null). - The EmitFastCloneShallowObject builtin now supports cloning slow object boilerplates. - Unified behavior to find the matching Map and instantiating it for Object.create(null) and literals with a null prototype. - Cleanup of literal type parameter of CompileTimeValue, now in sync with ObjectLiteral flags.

Properties can be defined inside the object literal (ES6) or after object creation. The behavior differes if there are accessors, interceptors or proxies in the Object prototype chain. These test cases assure we preserve correct behavior as we improve performance of definitions in literals.

We now only recognize "native function" when it occurs in extension scripts (parsing with a non-NULL extension), and only if there is no line-terminator between "native" and "function" (so that it would otherwise be a Syntax Error). Preparsing never recognizes native functions, which is acceptable since we never preparse extension scripts (because we don't allow lazy functions anyway).

Our testing infrastructure uses exceptions to indicate errors. assertUnreachable therefore throws an exception to indicate that it was reached. Therefore, it cannot be used to check that an exception was thrown using the pattern: try { shouldThrow(); assertUnreachable(); } catch(e) { } Such a test will always pass because assertUnreachable will throw an exception if shouldThrow does not.

instead of normal JSObjects. This ensures that __proto__ and accessors on the Object prototype do not interfere with catch scopes. Also, it fixes the bug that catch variables were not DontDelete (issue 74). Next step is to create special lookup routines for context extension objects and remove the special handling of context extension objects from the general javascript object lookup routines.

In the shell sample don't print the result of executing a script, only evaluating expressions. Fixed issue when building samples on Windows using a shared V8 library. Added visibility option on Linux build which makes the generated library 18% smaller. Changed build system to accept multiple build modes in one build and generate seperate objects, libraries and executables for each mode. Removed deferred negation optimization (a * -b => -(a * b)) since this visibly changes operand conversion order. Improved parsing performance by introducing stack guard in preparsing. Without a stack guard preparsing always bails out with stack overflow. git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@16 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
