This CL adds a speculative operator for BigInt negation that is lowered to the respective builtin call and is optimized to native 64 bit machine operations if truncated. In particular, this change allows negative BigInt constants (e.g. -5n) to be lowered.

The code generated for ChangeUint64ToBigInt in the EffectControlLinearizer did not initialize the optional padding field of newly allocated BigInts. This padding field is present on 64 bit builds without pointer compression enabled. This CL fixes this by 0-filling the padding field if present.

In essence, it simplifies the pattern (in x64): movl register, ___ movlsxlq register, register into: movlsxlq register, ___ This makes the code smaller and run faster, without compromising. We can do something similar for Arm64 too. The cases for Pointer and Any seem to be trickier but there seems to be room to improve as well.

Previously, we didn't have access checks for the megamorphic case cause we'd never get to this IC state for a receiver that doesn't hold the right private field. But now with lazy feedback allocation we share the megamorphic case code paths for the uninitialized loads as well, which exposes our bug.

This CL adds a new FreeList strategy, that can be turned on by using flag `--gc-freelist-strategy=1`. It is inspired by FreeListLegacy, and differs from it in the following ways: - Only has 3 categories: Medium, Large and Huge. - Any block that would have belong to tiniest, tiny or small in FreeListLegacy is considered wasted. - Allocation is done only in Huge, Medium and Large (in that order), using a first-fit strategy (only the first block of each freelist is ever considered though). - Performances is supposed to be better than FreeListLegacy, but memory usage should be higher (because fragmentation will probably be higher).

This change implements lowering of speculative BigInt addition as well as BigInt heap constants to corresponding int64 versions, if they are used in a context where the result is truncated to the least significant 64 bits (e.g. using asUintN). The JSHeapBroker is extended to provide access to the BigInt's least significant digit during concurrent compilation. The BigInt context (required to introduce correct conversions) is recognized in the RepresentationChanger by either the output type propagated downward or the TypeCheckKind propagated upward. This is necessary, because the TypeCheckKind may only be set by nodes that may potentially deopt (and sit in the effect chain). This is the case for SpeculativeBigIntAdd, but not for BigIntAsUintN. This CL contains a simple fix to prevent int64-lowered BigInts to flow into state values as the deoptimizer cannot handle them yet. A more sophisticated solution to allow the deoptimizer to materialize truncated BigInts will be added in a following CL.

Even though this is not spec'ed yet, it's good to have an implementation so that we can use clusterfuzz on it. I changed the parameter order (hopefully) everywhere to (table_dst_index, table_src_index, ...). This corresponds to the (dst, src, ...) parameter order for the entry indices.

This change fixes missing symbol errors in the Windows 10 on ARM build of Node.js. When a whole class is marked for export, all of its members are marked as well. This can be a problem when inline members call undefined yet inline members of other classes: the exported function will contain a reference to the undefined inline function that should be satisfied at link time, but because the other function is inline no symbol will be produced that will satisfy that reference. Clang gets around this by masking inlined class members from export using /Fc:dllexportInlines-. This is why b0a2a567 worked. Node.js' Windows builds use MSVC and so do not have access to this flag. This results in unresolved symbols at link time. Bug: v8:9465 Change-Id: Ief9c7ab6ba35d22f995939eb62a64d6f1992ed85 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1696771Reviewed-by:

This is a reland of https://crrev.com/c/v8/v8/+/1692366. The original change was reverted because it broke some blink tests. This will be landed after suppressing them: https://crrev.com/c/chromium/src/+/1695541 Make native errors serializable. The implementation is mostly straightforward, but there is one exception: the stack property. Although the property is not specified, the spec for error cloning asks us to preserve the property if possible. This implementation serializes the property only when it is a string, and otherwise ignores it.

With lazy feedback allocation and bytecode flushing we need to call %PrepareFunctionForOptimize before we call %OptimizeFunctionOnNextCall/ %OptimizeOsr. This cl: 1. Adds an additional state in pending optimized table to check if the optimization was triggered manually. 2. Changes the compilation pipeline to delete the entry from pending optimized table only if the optimization was triggered through %OptimizeFunctionOnNextCall / %OptimizeOsr. 3. Adds a check to enforce %PrepareFunctionForOptimize was called. 4. Adds a new run-time flag to only check in the d8 test runner. We don't want this check enabled in other cases like clusterfuzz that doesn't ensure %PrepareFunctionForOptimize is called.
