Otherwise, the quiet NaN bit might flip already when loading the float/double from memory or storing it. This fixes another NaN bit flip which happened on a single bot only.

Elements on typed arrays are never looked up in the prototype chain, so there's no point in depending on the prototype chain validity cells for keyed stores to typed arrays. You just risk going megamorphic for unrelated changes. Bug: v8:6999 Change-Id: Id831de42a2c9eadfd5317ee9b5dbfaa207f236fe Reviewed-on: https://chromium-review.googlesource.com/737789Reviewed-by:

It appears in the cctest context, both the old STUB, and the current WASM_FUNCTION "just work"; however, in the upcoming off-the-gc wasm world, we codegen call sites differently on x64 - far calls for js-to-wasm (this case), and near calls otherwise.

Clemens Hammacher authored
Before, the standard way to create a RegList was either: RegList list = (1 << 0) | (1 << 1) | ... or RegList list = rax.bit() | rdx.bit() | ... The first way allows to make the RegList constexpr, but needs comments to document which registers you are referring to, and it has no checks that all bits you set on the RegList actually belong to valid registers. The second one uses the symbolic names, hence is much more readable and makes it harder to construct invalid RegLists. It's not constexpr though, since the {bit()} method on the register types is not constexpr. This CL adds a constexpr accessor to get the code and bit of a constexpr Register, and adds a helper method to create a constexpr RegList like this: constexpr RegList list = Register::ListOf<rax, rdx, rdi>(); This new method is used in a number of places to test its applicability. Other uses of the old pattern remain and can be cleaned up later.

This removes all but one caller of Literal::raw_value(), thus hiding AstValue from the rest of the codebase. This is in preparation to move much of AstValue's implementation up into Literal itself, thus avoiding the overhead of the underling ZoneObjects and allowing us to remove complexity such as the cache of Smi-valued AstValues.

This moves bits that are accessed during a stack-walk out if the first kind-specific flags field. Such bits are accessed during evacuation within the GC and hence need to remain directly in the {Code} object, the other bits in the kind-specific flags are mutable and hence will be moved into a separate data container object.

Our first implementation passed the source position as argument to the runtime function, which would then generate an Error object, patch the contained stack trace to point to the position given as argument, and then throw the Error. Since all our paths are now changed to call a builtin with proper source position information, we do not need to patch anything any more.

When lowering a monomorphic load/store, where multiple receiver maps have been recorded, but the action to be performed is the same (i.e. yielding undefined because the property is not found), TurboFan used to ignore the Smi case, leading to a pretty terrible deoptimization loop, as the LOAD_IC/STORE_IC properly recorded that state and thus didn't change it's state. Fixing this issue gives a 18-20% boost on the prettier test of the web-tooling-benchmark, which was suffering a lot from this problem.
