This also adds speculative checks asserting that all arguments are of the right types; each check disables speculation if it fails.

For numbers, `JSGraph::Constant(Handle<Object> value)` first checks the type of `value`, and then calls `JSGraph::Constant` for its type, which in turn performs some further checks before returning a value. This patch saves a few `if` checks by making the following changes: - JSGraph::Constant(0) → JSGraph::ZeroConstant() - JSGraph::Constant(1) → JSGraph::OneConstant() Change-Id: I6946c280437b7f1fe80d7c45c6fd9b3571907e07 Reviewed-on: https://chromium-review.googlesource.com/840982Reviewed-by:

We have a heuristics that allows the main thread to skip marking work by the amount marked by the background tasks. Scavenges that happen during incremental marking can reclaim marked objects, which should be accounted in the main thread marking schedule.

NodeProperties::InferReceiverMaps now traverses effect chain for Loop-EffectPhi nodes, which makes it possible to inline `iterator.next()` within a loop when the next property is loaded outside of a loop. A new helper, GetInstanceTypeWitness(), performs InferReceiverMaps() and checks that each resulting map has an identical instance type.

This is the implementation of crrev.com/c/766371 for mips. Original description: Add the ability to return (multiple) return values on the stack: - Extend stack frames with a new buffer region for return slots. This region is located at the end of a caller's frame such that its slots can be indexed as caller frame slots in a callee (located beyond its parameters) and assigned return values. - Adjust stack frame constructon and deconstruction accordingly. - Extend linkage computation to support register plus stack returns. - Reserve return slots in caller frame when respective calls occur. - Introduce and generate architecture instructions ('peek') for reading back results from return slots in the caller. - Aggressive tests. - Some minor clean-up.

This patch updates the instruction selector and code generator to pad arguments for arm64 and drop an even number of slots when dropping the arguments. It also updates the builtins that handle arguments. These changes need to be made at the same time. It also adds some tests for forwarding varargs, as this was affected by the builtin changes and the existing tests did not catch all issues.
