Without this fix, we create a new state-values node for parameters per environment. This is especially bad for heavily branching functions. With the fix, we should only create one node per function.

Preparser does not keep track of function names. If we want to parse top-level function and top-level code was only preparsed we need to parse the function name again.

When cross compiling inspector with GYP on MIPS and ARM, there are three rules that generate the same file both host toolset and target toolset. This causes problems because of rule duplication; depending on compilation configuration this can cause warning or error.

There's no reason to keep track, for a preparsed function itself, whether that function calls eval. All that matters is that the ancestor scopes are marked as having an inner scope which calls eval. The function will have its "calls eval" bit persisted if/when it's fully parsed. The only "behavioral" change in this patch is the removal of a DCHECK.

let/const declarations in "standard" C-style for-loops have some complex desugaring to accommodate the case where loop loop variables may be captured. This slows down the baseline performance of for-loops with let variables. This change attempts to avoid this desugaring if it's known that the loop variable is not captured at any point. A side effect of this change is that let/const loop variables, when not captured within the loop body, are not necessarily shown in the debugger, similar to other stack-allocated vars.

Move JSOrdinaryHasInstance lowering to JSNativeContextSpecialization, which was previously mostly done in JSTypedLowering (for no reason). Add new logic to the lowering to constant-fold OrdinaryHasInstance checks when the map of the left-hand side and the "prototype" of the right-hand side is known. This address the performance issue with the (base) class constructors generated by Babel, i.e.: function _classCallCheck(instance, Constructor) { if (!(instance instanceof Constructor)) { throw new TypeError("Cannot call a class as a function"); } } var C = function C() { _classCallCheck(this, C); }; for class C {} Also ensure that a known constructor being used inside an instanceof get's a proper initial map on-demand.

This includes a fastpath in the ElementsAccessor for the source array being a JSArray with FastSmi or FastDouble packed kinds. This is probably a pretty common usage, where an array is passed in as a way of initializing the TypedArray at creation (as there is not other syntax to do this). e.g. new Float64Array([1.0, 1.0, 1.0]) for some sort of vector application.

The StringIndexOf fast path used to be very narrow, only allowing one-byte single-char search strings (and a one-byte subject string). This changes the CSA fast path to call into our internal SearchString C++ function instead (after attempting to unpack both Strings), and can handle strings of arbitrary length and encoding.

This fixes source position tracking within the "increment" expression of a for-statement. The old {StashCode} method was inherently incompatible with side tables like the source position table, as it would leave them untouched while mutating the bytecode stream.

Functions that take mandatory parameters plus a number of optional parameters, that need to be materialized as an Array are quite common. The simplest possible case of this is essentially: function foo(mandatory, ...args) { return args; } Babel translates this to something like: function foo(mandatory) { "use strict"; for (var _len = arguments.length, args = Array(_len > 1 ? _len - 1 : 0), _key = 1; _key < _len; _key++) { args[_key - 1] = arguments[_key]; } return args; } The key to great performance here is to make sure that we don't materialize the (unmapped) arguments object in this case, plus that we have some kind of fast-path for the Array constructor and the initialization loop. This microbenchmark ensures that we have decent performance even in the case where the assignment to args is polymorphic, i.e. the arguments have seen different elements kinds, starting with FAST_HOLEY_ELEMENTS and then FAST_HOLEY_SMI_ELEMENTS.
