This is a reland of 0896599f with a fix for failing layout test. Original change's description: > Change SetProperty/SetSuperProperty to infer language mode when possible > > In most cases, the language mode can be inferred from the closure and > the context. Computing the language mode instead of passing it around > simplifies the ICs and will make it possible to go towards lazily > allocating feedback vectors. Currently ICs obtain the language mode from > the feedback vectors and with lazy feedback allocation we may not always > have feedback vectors. Since computing language mode is a bit expensive > we want to defer it as far as possible. > > In Array builtins and other builtins like Reflect.Set we need to force a > language mode when setting the properties. To support these cases the > SetProperty methods allow the language mode to be overridden when needed. > > This is a first cl in a series of cls, that will defer the language mode > computation further and remove language mode where it is not needed. > > BUG: v8:8580 > Change-Id: I9c2396e3bcfe77c3c9d6760c46d86954d54744b9 > Reviewed-on: https://chromium-review.googlesource.com/c/1409426 > Reviewed-by: Michael Lippautz <mlippautz@chromium.org> > Reviewed-by: Jakob Gruber <jgruber@chromium.org> > Reviewed-by: Toon Verwaest <verwaest@chromium.org> > Commit-Queue: Mythri Alle <mythria@chromium.org> > Cr-Commit-Position: refs/heads/master@{#58893} TBR: ahaas@chromium.org Change-Id: Id5d81eae91b55638dbc72168f0e5203e684869fb Reviewed-on: https://chromium-review.googlesource.com/c/1421077 Commit-Queue: Mythri Alle <mythria@chromium.org> Reviewed-by:

If a value dies in deferred code, there is no need to reload it at the end of the deferred code, as it will be dead in the non-deferred code that follows in control flow order. In the linearized view of register allocation, this is encoded as a lifetime gap (or the end of an interval). Moreover, this may lead to wrong assignments if the value dies between two deferred blocks and we leave a non-splintered live range in the middle of deferred code.

Other platforms besides ARM64 Windows may also have alignment requirements, e.g. PPC and s390. These requirements may affect both the code pointer field and the size field, and so they each need alignment directives because they are stored in different sections. Since aligning wastes a handful of bytes at most, not making alignment conditional on the platform type seems like a good idea.

This requires honoring the instance size of the object stored in the map for JSObject. To do this, allocation is now split into two instrinsics, one that calculates the base size of the allocated object (%GetAllocationBaseSize) and one that actually allocates (%Allocate). In the process, remove objects.tq, which only existed to contain a macro to fetch the default JSObject map, which is functionality that is now in the JSObject class constructor.

For the reference types anyref, anyfunc, and nullref, there exist sub-typing rules. The spec says A reference type reftype1 matches a reference type reftype2 if and only if: * Either both reftype1 and reftype2 are the same. * Or reftype1 is nullref. * Or reftype2 is anyref. This CL introduces the type nullref for ref-null, and implements the sub-typing rules in the function-body-decoder. Note that because of the sub-typing check validation performance may regresses. In that case we can optimize the sub-typing check.
