      [wasm][debug] Move breakpoint cctests to Liftoff · 780746d6
      Clemens Backes authored
      The cctests for breakpoints were still executing in the interpreter.
      This CL moves them over to Liftoff.
      
      Note that the additional methods on {DebugInfo} will be reused for other
      purposes, see https://crrev.com/c/1941139.

      [offthread] Check memory pressure after merging · 5b878283
      Leszek Swirski authored
      Currently, there is no indication of memory pressure after merging pages
      from off-thread space into the heap. This can mean that with lots of
      off-thread compilations, we eventually run out of pages in the memory
      allocator.
      
      Now, trigger a critical memory pressure notification after merging if
      the old generation is close to being unexpandable. We may want to add
      other heuristics here (e.g. moderate memory pressure if the heap is
      highly fragmented), or possibly add similar checks when the off-thread
      space is initialized, but this works for now.
      
      As a drive-by, inline the NotifyOffThreadSpaceMerged call into the
      off-thread factory merge -- we already do a bunch of special merging
      stuff in there, and nowhere else, so we may as well be explicit in what
      we're actually doing. This also allows us to do a pre-check on old-space
      size and hard limits just before the merge.

      Reland "[offthread] Move stress-background-compile to compiler.cc" · 471b2001

      This is a reland of a441cbfb
      
      Disabling cctest/test-compiler/DeepEagerCompilationPeakMemory in stress

      > Make --stress-background-compile a V8 flag rather than a d8 flag, so

      > One of the necessary changes to allow tests to pass was to introduce a

      [offthread] Disable off-thread compiles for block coverage · 7712da4d
      Leszek Swirski authored
      Off-thread compilation currently doesn't support adding DebugInfo to a
      SharedFunctionInfo, so it also doesn't support adding coverage info.
      
      For now, disable off-thread finalization entirely when block coverage
      is enabled. In the future we most likely want to add support for this.

      Revert "[builtins] Clean up the use of class_name / ES5 [[Class]]" · 213016d6
      Bill Budge authored
      This reverts commit 29c1eab9.
      
      Reason for revert: Causes Blink test failures:
      https://ci.chromium.org/p/v8/builders/ci/V8%20Blink%20Linux/4222
      
      Original change's description:
      > [builtins] Clean up the use of class_name / ES5 [[Class]]
      > 
      > Before ES2015, the ES spec had a [[Class]] internal slot for all
      > objects, which Object.prototype.toString() would use to figure the
      > returned string. Post-ES2015, the [[Class]] slot was removed in spec for
      > all objects, with the @@toStringTag well-known symbol the proper way to
      > change Object.prototype.toString() output.
      > 
      > At the time, spec-identical handling without the use of [[Class]] was
      > implemented in V8 for all objects other than API objects, where issues
      > with the Web IDL spec [1] prevented Blink, and hence V8, to totally
      > migrate to @@toStringTag. However, since 2016 [2] Blink has been setting
      > @@toStringTag on API class prototypes to manage the
      > Object.prototype.toString() output, so the legacy [[Class]] handling in
      > V8 has not been necessary for the past couple of years.
      > 
      > This CL removes the remaining legacy [[Class]] handling in
      > Object.prototype.toString(), JSReceiver::class_name(), and
      > GetConstructorName(). However, it does not remove the class_name field
      > in FunctionTemplateInfo, as it is still used for the `name` property of
      > created functions.
      > 
      > This CL also cleans up other places in the codebase that still reference
      > [[Class]].
      > 
      > This change should have minimal impact on web-compatibility. For the
      > change to be observable, a script must do one of the following:
      > 
      > 1. delete APIConstructor.prototype[Symbol.toStringTag];
      > 2. Object.setPrototypeOf(apiObject, somethingElse);
      > 
      > Before this CL, these changes will not change the apiObject.toString()
      > output. But after this CL, they will make apiObject.toString() show
      > "[object Object]" (in the first case) or the @@toStringTag of the other
      > prototype (in the latter case).
      > 
      > However, both are deemed unlikely. @@toStringTag is not well-known
      > feature of JavaScript, nor does it get tampered much on API

      > Currently, @@toStringTag-based API object branding is not yet
      > implemented by other browsers. This V8 bug in particular has been an
      > impediment to standardizing toString behavior. Fixing this bug will
      > unblock [3] and lead to a better Web IDL spec, and better toString()
      > compatibility for all.
