      Reland^2 "[ptr-cage] Rename IsolateRoot to PtrComprCageBase" · 627b6b2f
      Shu-yu Guo authored 
      This is a reland of e28dadc2

The original failure was due to a stale Win32 bot. The reland failure
was due to idempotent task deduplication returning the exact same
failure. See crbug/1196064

      Currently, IsolateRoot is both the address of the Isolate root and the
base address of the pointer compression reservation. This CL teases the
two uses apart by renaming IsolateRoot to PtrComprCageBase.

- In addition to V8_COMPRESS_POINTERS, add a
  V8_COMPRESS_POINTERS_IN_ISOLATE_CAGE (vs SHARED_CAGE).

- Rename GetIsolate* helpers to GetPtrComprCageBase. When
  V8_COMPRESS_POINTERS_IN_ISOLATE_CAGE is true, the helpers remain as
  aliases to GetPtrComprCageBase.

- Rename kPtrComprIsolateRootAlignment to kPtrComprCageBaseAlignment.

      [compiler] Add the MapUpdater lock · 605f9875
      Jakob Gruber authored 
      It's locked exclusively in the MapUpdater API methods, and locked
shared in ComputePropertyAccessInfo (CPAI).

This lock is a step towards running CPAI on background threads. The
simple lock portion is landed separately in this CL to get an early
signal on potential lock overhead perf impact.

The lock is implemented and used very conservatively at the moment:

- it's a single global lock (and not e.g. per-map).
- it's locked for the entire method call duration (instead of only in
  relevant parts).

Both points can potentially be improved in the future.

      [sparkplug][deoptimizer] Deoptimize to baseline. · bdcd7d79
      Patrick Thier authored 
      If we have baseline code, deoptimize to baseline instead of the
interpreter. The process is similar to deopting to the interpreter.
We just use different builtins
(BaselineEnterAtBytecode/BaselineEnterAtNextBytecode) instead of
InterpreterEnterBytecodeDispatch/InterpreterEnterBytecodeAdvance, that
patch an interpreter frame to a baseline frame and continue execution in
baseline code (based on the deopt type, at the current or next
bytecode).

      Reland "[TurboFan] Move FunctionTemplateInfo to never serialized" · 07db5a65
      Nico Hartmann authored 
      This reverts commit c85b7a44.

This reland fixes missing serialization of objects stored in
CallHandlerInfo::data by adding necessary handling of these objects
in FunctionTemplateInfoRef::SerializeCallCode when running with
direct heap access.

Drive-by: Remove declaration of CallHandlerInfoRef::Serialize, which
did not have a definition.

Original change's description:
> [TurboFan] Move FunctionTemplateInfo to never serialized
>
> This CL moves FunctionTemplateInfo to the list of never serialized
> objects, allowing direct heap reads. To make this threadsafe, the CL:
> - adds necessary atomic (relaxed/acquire-release) operations to the
>   accessors of FunctionTemplateInfo.
> - changes FunctionTemplateInfoRef::LookupHolderOfExpectedType to be
>   usable from the background thread (e.g. no handle construction) with
>   the caveat of skipping optimization in some cases where necessary
>   JSObjects are not serialized.
>
> Drive-by: Add missing serialization of objects possibly reachable
> through CallHandlerInfo::data.
