We need script source for: - calculating hash to report as part of scriptParsed event, - reporting it as response on getScriptSource request, - searching inside as response on searchInContent request, - breakpoints hints. In all cases there is no need to store source on inspector side.

This call can be used by embedder to request a GC for testing reasons. The GC also takes the current embedder stack state as an argument that is forwarded to the embedder when entering the atomic pause. This way embedders can request garbage collections for testing and set how the embedder should treat the stack.

Refactor the ArrayIteratorPrototypeNext CSA builtin to handle the JSArray element access in a dedicated helper macro, very similar to how it's done for JSTypedArray's. Also add support for dictionary elements to this helper macro using the existing dictionary access logic in the CodeStubAssembler. This improves the readability of the builtin significantly and the performance of iterating arrays with dictionary elements goes up by a factor of ~3.5x.

This patch splits the log file into a vector of std::strings when logging is stopped, so verifying that lines are present can be done in terms of std library functions. Verifications are now done by simple substring matching instead of via a prefix or suffix, in preparation for a new test that needs to match the middle of a line. This patch also deletes some dead/debugging code. Change-Id: I5c6b75b0807c41312d35208deda26546dc0f7216 Reviewed-on: https://chromium-review.googlesource.com/1183187Reviewed-by:

Inspector tries to provide sourceURL and sourceMappingURL for scripts with parser errors. Without this CL we convert source of each script to inspector string and search for magic comment there. Some web sites use pattern when they get some data from network and constantly try to parse this data as JSON, in this case we do a lot of useless work. So we can parse magic comments on V8 side only for compilation errors (excluding parse JSON errors), to do it we can reuse scanner by running it on each potential comment.

This populates the isolate-independent builtin whitelist with initial builtins that do not access any isolate-dependent data and thus don't need the root register at all. Unlike most other platforms, we can't use a scratch register in the off-heap trampoline since there's no free register available. The trampolines on ia32 are thus implemented as pc-relative jumps (thankfully we can address the entire address space). Drive-by: Made Code::IsIsolateIndependent consistent with FinalizeEmbeddedCodeTargets. Code targets are only allowed on some platforms.

Benedikt Meurer authored
Instead of changing the [[IteratedObject]] field to undefined to mark an array iterator as exhausted, store the appropriate maximum value into the [[ArrayIteratorNextIndex]] field such that the iterator will never produce any values again. Without this change the map check and the "length" access on the [[IteratedObject]] cannot be eliminated inside the loop, since the object can either be the array or undefined. Even with this change it's still not possible immediately due to missing aliasing information in the LoadElimination, but it paves the way for follow up improvements. Eventually the goal is to have `for..of` as fast as a traditional `for` loop even for really tight loops. This CL also hardens the implementation of the ArrayIterator by using proper CASTs and CSA_ASSERTs. The readability of the CSA builtin was improved by utilizing proper helper functions.

Toon Verwaest authored
This reverts the following 3 CLs: Revert "[scanner] Templatize scan functions by encoding" Revert "[asm] Remove invalid static cast of character stream" Revert "[scanner] Prepare CharacterStreams for specializing scanner and parser by character type" The original idea behind this work was to avoid copying, converting and buffering characters to be scanned by specializing the scanner functions. The additional benefit was for scanner functions to have a bigger window over the input. Even though we can get a pretty nice speedup from having a larger window, in practice this rarely helps. The cost is a larger binary. Since we can't eagerly convert utf8 to utf16 due to memory overhead, we'd also need to have a specialized version of the scanner just for utf8. That's pretty complex, and likely won't be better than simply bulk converting and buffering utf8 as utf16.
