This CL changes the sorting algorithm used in Array.p.sort from QuickSort to TimSort (implemented in Torque). Detailed performance results can be found here: https://goo.gl/4E733J To save on code space, fast-paths are implemented as sets of function pointers instead of specializing generics.

The idea is to compute the slack before compilation start. Then we check that the slack tracking decision is the same at the end of compilation. If it is, we just commit to that slack tracking (by calling function->CompleteInobjectSlackTrackingIfActive). If the slack tracking decision changed, we will retry the compilation. This has several pieces: - Expose computation of slack and instance size from the object model. - Add compilation dependency on the slack tracking result. - Change create lowering to use the dependency. - Fix array creation to use the slack tracking result's instance size.

Port d324382e and Port bd3f0a68 Original Commit Message: This is a reland of a462a785 Original change's description: > [turboassembler] Introduce hard-abort mode > > For checks and assertions (mostly for debug code, like stack alignment > or zero extension), we had two modes: Emit a call to the {Abort} > runtime function (the default), and emit a debug break (used for > testing, enabled via --trap-on-abort). > In wasm, where we cannot just call a runtime function because code must > be isolate independent, we always used the trap-on-abort behaviour. > This causes problems for our fuzzers, which do not catch SIGTRAP, and > hence do not detect debug code failures. > > This CL introduces a third mode ("hard abort"), which calls a C > function via {ExternalReference}. The C function still outputs the > abort reason, but does not print the stack trace. It then aborts via > "OS::Abort", just like the runtime function. > This will allow fuzzers to detect the crash and even find a nice error > message. > > Even though this looks like a lot of code churn, it is actually not. > Most added lines are new tests, and other changes are minimal. > > R=mstarzinger@chromium.org > > Bug: chromium:863799 > Change-Id: I77c58ff72db552d49014614436259ccfb49ba87b > Reviewed-on: https://chromium-review.googlesource.com/1142163 > Commit-Queue: Clemens Hammacher <clemensh@chromium.org> > Reviewed-by: Michael Starzinger <mstarzinger@chromium.org> > Cr-Commit-Position: refs/heads/master@{#54592} R=clemensh@chromium.org, joransiu@ca.ibm.com, michael_dawson@ca.ibm.com BUG= LOG=N Change-Id: I60023470fa07576fd313f628ade06e279d5f4927 Reviewed-on: https://chromium-review.googlesource.com/1165822 Commit-Queue: Junliang Yan <jyan@ca.ibm.com> Reviewed-by:

This patch ports most of the Intl.Collator from JS to C++. The Intl.Collator object no longer stores all the resolved values. Instead these are looked up on demand as part of Intl.Collator.prototype.resolvedOptions(), saving several words. In the future, we can cache the result of the resolvedOptions as well. In this patch, we use ICU to do parsing of the unicode extension in the bcp47 language tag instead of using a custom extension parser. This patch also fixes several spec compliance bugs as well.
