      MIPS64: VectorICs: keyed element loads were kicking out non-smi keys unnecessarily · fe0d860b
      akos.palfi authored 
      Port 6689cc27

Original commit message:
Handlers should be in charge of this work. The change uncovered a bug in
vector-ics related to keyed loads into strings. It's important for
StringCharCodeAtGenerator, a helper used in full code and in
LoadIndexedStringStub (a handler) to protect the vector and slot registers
when it makes a runtime call to convert a HeapNumber to a Smi.

It's still possible for the handler to MISS after this call, perhaps due
to out of bounds access. In that case, the vector and slot registers need
to be delivered safely to the MISS handler.

      PPC: Remove kind field from StackHandler. · 890c0eac
      michael_dawson authored 
      Port 15f82138

Original commit message:
This relands commit 96f79568.

This makes the Isolate::Throw logic not depend on a prediction of
whether an exception is caught or uncaught. Such a prediction is
inherently undecidable because a finally block can decide between
consuming or re-throwing an exception depending on arbitray control
flow.

There still is a conservative prediction mechanism in place that
components like the debugger or tracing can use for reporting.

With this change we can get rid of the StackHandler::kind field, a
pre-requisite to do table-based lookups of exception handlers.
