This addresses a TODO in JSTypedLowering and generally makes the more easier to follow since the methods deal only with one kind of Node now. Bug: v8:8015 Change-Id: I8c3521b8d630dbe272264dc01e9ab3a5b0a8f682 Reviewed-on: https://chromium-review.googlesource.com/1196883Reviewed-by:

This CL removes a regression test that was intended to check that the maximum call stack size was not exceeded when calling Array.p.sort. As the new sorting algorithm (TimSort) does not work recursively, this test is no longer really necessary. It is also rather slow and causes issues on some bots, so we remove the test.

This adds experimental support for an 'except_ref' value type for caught exceptions as per the exception handling proposal. In the current for it is only allowed to have such types in the stack or in a local, support for having it as part of any signature was left out. The default value for a local of type 'except_ref' is the 'ref_null' value for now. Since this value cannot escape a wasm function, the concrete value is not actually observable.

This is no longer necessary as the JSFunction::code field is now a proper tagged field, that points to a Code object, instead of a naked pointer into the beginning of the Code object. So now the representation selection always sees a proper tagged value here.

This CL improves the performance of creating [...a, b] or [...a]. If the array literal has a leading spread, this CL emits the bytecode [CreateArrayFromIterable] to create the literal. CreateArrayFromIterable is implemented by [IterableToListDefault] builtin to create the initial array for the leading spread. IterableToListDefault has a fast path to clone efficiently if the spread is an actual array. The bytecode generated is now shorter. Bytecode generation is refactored into to BuildCreateArrayLiteral, which allows VisitCallSuper to benefit from this optimization also. For now, turbofan also lowers the bytecode to the builtin. The idiomatic use of [...a] to clone the array a now performs better than a simple for-loop, but still does not match the performance of slice.

This changes SimplifiedLowering to be more consistent when chosing Smi representation as input for Number comparisons. We already had some isolated logic for doing (speculative) Number comparisons on Smis, but only in the case where that decision was based on type feedback, not on information already present in the graph.

This removes the thread-local field in question. This side-channel for the "caught exception" is not needed, we can just explicitly pass the exception value to all support functions. Also, there is an inherent problem with having this side-channel, as it will not be properly reset when an exception handler ends up not rethrowing the exception.

Explicitly zeroing these in code-gen is not required because - - The spec requires only the data exchange to be atomic, for narrow ops this uses only the low word. - The return values are not in memory, so are not visible to other workers/threads BUG:v8:6532 Change-Id: I90a795ab6c21c70cb096f59a137de653c9c6a178 Reviewed-on: https://chromium-review.googlesource.com/1194428Reviewed-by:

On 32-bit platforms, String::kMaxLength is such that not all BigInts can be converted to Strings. NoSideEffectsToString, however, used to assume that this conversion always succeeds. This patch adds a check for the failure case, and returns "<a very large BigInt>" instead of crashing. This change is practically unobservable, because actually formatting such a huge BigInt to String would take "forever", which is also why there is no regression test.
