[runtime] use new CloneObject bytecode for some ObjectLiteralSpread cases · b6f7ea58

Caitlin Potter authored Jul 20, 2018

As discussed in
https://docs.google.com/document/d/1sBdGe8RHgeYP850cKSSgGABTyfMdvaEWLy-vertuTCo/edit?ts=5b3ba5cc#,

this CL introduces a new bytecode (CloneObject), and a new IC type.

In this prototype implementation, the type feedback looks like the
following:

Uninitialized case:
  { uninitialized_sentinel, uninitialized_sentinel }
Monomorphic case:
  { weak 'source' map, strong 'result' map }
Polymorphic case:
  { WeakFixedArray with { weak 'source' map, strong 'result' map }, cleared value }
Megamorphic case:
  { megamorphic_sentinel, cleared_Value }

In the fast case, Object cloning is done by allocating an object with
the saved result map, and a shallow clone of the fast properties from
the source object, as well as cloned fast elements from the source object.
If at any point the fast case can't be taken, the IC transitions to the
slow case and remains there.

This prototype CL does not include any TurboFan optimization, and the
CloneObject operation is merely reduced to a stub call.

It may still be possible to get some further improvements by somehow
incorporating compile-time boilerplate elements into the cloned object,
or simplifying how the boilerplate elements are inserted into the
object.

In terms of performance, we improve the ObjectSpread score in JSTests/ObjectLiteralSpread/
by about 8x, with substantial improvements over the Babel and ObjectAssign scores.

[turboassembler] Introduce hard-abort mode · a462a785

Clemens Hammacher authored Jul 20, 2018

For checks and assertions (mostly for debug code, like stack alignment
or zero extension), we had two modes: Emit a call to the {Abort}
runtime function (the default), and emit a debug break (used for
testing, enabled via --trap-on-abort).
In wasm, where we cannot just call a runtime function because code must
be isolate independent, we always used the trap-on-abort behaviour.
This causes problems for our fuzzers, which do not catch SIGTRAP, and
hence do not detect debug code failures.

This CL introduces a third mode ("hard abort"), which calls a C
function via {ExternalReference}. The C function still outputs the
abort reason, but does not print the stack trace. It then aborts via
"OS::Abort", just like the runtime function.
This will allow fuzzers to detect the crash and even find a nice error
message.

Even though this looks like a lot of code churn, it is actually not.
Most added lines are new tests, and other changes are minimal.

[iwyu] Add script to check that headers can be included in isolation · 4b412577

Clemens Hammacher authored Jul 20, 2018

The most important point of IWYU (include-what-you-use) is that each
header includes everything it is using, so that whoever includes that
header does not need to additionally include other things.
This CL adds a script which generates files to automatically check this.
It is automatically invoked during "gclient runhooks" if the
"check_v8_header_includes" variable is set. This script generates a
number of .cc files in the "check-header-includes" directory, together
with a "sources.gni" file which lists all the generated cc files. Each
file includes one header.
If additionally the gn args "v8_check_header_includes" is set, this gni
file is included, and all the generated CC files will be compiled. This
will detect violations of the aforementioned IWYU rule.

Reland "[wasm] Improve module code size sampling approach." · 35f674cc

Michael Starzinger authored Jul 19, 2018

This is a reland of 0f2d22dd

Original change's description:
> [wasm] Improve module code size sampling approach.
> 
> This samples module code sizes at GC time instead of during destruction.
> It hence makes sure that we also receive samples for long-lived modules
> which would otherwise die with the Isolate and never be finalized. Note
> that this approach is still biased and just a stop-gap until we have a
> sampling tick based on actual wall-clock time.

[wasm] Fix AtomicStores to not clobber the output register · 84efdf02

Deepti Gandluri authored Jul 19, 2018

Currently AtomicStores use AtomicExchange to store to memory, but
AtomicExchange produces an output that is ignored by the AtomicStore
visitor, a side effect of this is that a register already in use gets
overwritten by the output of the exchange.
