      Expose v8::TypedArray::kMaxLength. · 19fee8b2
      Jeremy Roman authored 
      There is an API check failure if values larger than i::Smi::kMaxValue are
provided, but it is inconvenient for API users to know what this value is
(and SIZE_MAX and INT_MAX are both incorrect).

This is analogous to v8::String::kMaxLength.

      PPC/s390: Replacing pc with trampoline on stack (gc-stress fix) · 57a78181
      Jaideep Bajwa authored 
      Port 895c3219

Original Commit Message:

    Replacing pc with trampoline on stack
    This CL is the follow up of https://chromium-review.googlesource.com/c/586707/
    which used to crash when running the gc-stress bots.
    It seems to be working now. We now keep the trampoline PC in the Safepoint
    table and use that information to find SafepointEntries.

    There's some refactoring that can be done, such as changing the code for
    exceptions in a similar way and removing the trampoline from the
    DeoptimizationInputData. Will take care of this in the next CL.

      [inspector] move breakpoint management to native · cd9e86a5
      Alexey Kozyatinskiy authored 
      My goal was to move breakpoint API to native with minimal changes around, so on inspector side we use v8::debug::BreakpointId instead of String16, on v8::internal::Debug we use i::BreakPoint object instead of break point object created inside of debug.js.

There are a lot of opportunities how we can improve breakpoints (at least we can avoid some of linear lookups to speedup implementation) but I think that as first step we need to remove mirrors/debug.js APIs.

Drive by: debugger-script.js and usage of debugger context in inspector code base.

      Start migration of try/throw/catch to match proposal. · 470a1001
      Karl Schimpf authored 
      This CL does the first baby steps on moving the current (experimental)
exception handling to match that of the WebAssembly proposal.

It does the following:

1) Use exception tags instead of integers.

2) Only handle empty exception signatures (i.e. no values associated
   with the exception tag.

3) Only handle one catch clause.

4) Be sure to rethrow the exception if the exception tag does not match.

Note: There are many things that need to be fixed, and are too
numerous to list here. However, the code should have TODO's on each
missing parts of the implementation.

Also note that the code currently doesn't handle nested catch blocks,
nor does it change the throw value being an integer. Rather, the
integer value is still being thrown, and currently is the exception
tag. Therefore, we don't build an exception object. This is the reason
why this CL doesn't handle exceptions that pass values.

Also, the current implementation still can't handle multiple modules
because tag resolution (between) modules has not be implemented yet.
