      [inspector] introduced debug::SetBreakEventListener,SetExceptionEventListener · f3dcdf88
      kozyatinskiy authored 
      Inspector is moved to per-event-type callbacks instead of general v8::debug::SetDebugEventListener. It allows to:
- remove any usage of v8::Debug::EventDetails in debug-interface,
- avoid redundant JS call on each event to get properties of event objects,
- introduce better pure C++ API for these events later.

      Implement ldrex/strex instructions in ARM simulator · 66ae5f7d
      binji authored 
      This CL implements ldrex, ldrexb, ldrexh, strex, strexb, and strexh in the
Simulator. These instructions provide "exclusive" access, which provides mutual
exclusion for concurrent threads of execution.

The ARM specification gives some leeway to implementors, but essentially
describes each processor as having Local Monitor and Global Monitor. The Local
Monitor is used to check the exclusivity state without having to synchronize
with other processors. The Global Monitor is shared between processors. We
model both to make it easier to match behavior with the spec.

When running with multiple OS threads, each thread has its own isolate, and
each isolate has its own Simulator. The Local Monitor is stored directly on the
Simulator, and the Global Monitor is stored as a lazy singleton. The Global
Monitor maintains a linked-list of all Simulators.

All loads/stores (even non-exclusive) are guarded by the Global Monitor's mutex.

      [inspector] unconditionally pause on OOM · 9662547c
      kozyatinskiy authored 
      Currently V8 context just crashes on OOM, with this CL backend will send paused notification with OOM reason before OOM and will increase heap limits to allow further debugging on pause.

      [turbofan] Also recognize 'type' === typeof x. · ff46966d
      bmeurer authored 
      So far we only recognized

  typeof x == 'type'
  typeof x != 'type'
  typeof x === 'type'
  typeof x !== 'type'

but some people seem to prefer it the other way around, i.e.

  'type' == typeof x
  'type' != typeof x
  'type' === typeof x
  'type' !== typeof x

as spotted in some Ember.js code, so we should obviously handle that as
well and reduce it to a quick check on x instead of calling the TypeOf
builtin and comparing the resulting string.

      [turbofan] Regalloc was assuming "blocked" register can't be "used" · 970d9076
      mtrofin authored 
      When attempting to allocate a blocked register, in the absence of
aliasing, it was possible to assume that a register that was
blocked - by either belonging to an active fixed register, or to
an active unspillable range - could not have possibly be allocated
to another active range (because there'd be an interference otherwise).

With aliasing, that changes. The range we're trying to allocate
may be a double, while the 2 or more active ranges in the paragraph
above may be singles aliasing to the same double slot.

Opportunistically refactored for readability an optimization, and
added some comments.
