Currently function name inference is wired with AST optimization pass to avoid introducing another pass over AST. A better solution would be to rewrite AST visitors so they can be naturally combined together in a single pass, as their current implementation doesn't allow it.

For examples of cases where function names can be inferred, see the tests file.

As I discovered that JSFrame accesses SharedFunctionInfo only to calculate caller SP and the latter is not used in profiler's stack sampling, I disabled accessing heap objects in JSFrame when doing stack sampling. This finally made V8's profiling stable when used from Chrome on a real web app.

For function.call debug step in did not work as execution did not break in the function called. This has now been fixed using the same means as for function.apply in CL http://codereview.chromium.org/63055.

The generic step-in mechanism floods the function called with break points to ensure a break is hit when entering the function. This generic mechanism was also used for function.apply. The code for function.apply contains a keyed load IC which was patched when stepping into function.apply. However function.apply enteres an internal frame not a JavaScript frame. This caused the logic for returning from the break in function.apply to fail as it forced a jump to the IC on the top JavaScript frame. The top JavaScript frame was the frame for the function calling function.apply not the frame for the apply function. Now returning from the break point in the keyed load IC in the apply code caused a jump to the code for the call IC for the function calling function.apply in the first place. Not a pretty sight.

Step-in now handles function.apply as a separate case where the actual JavaScript function called through apply is flodded with breakpoints instead of the function.apply function.

V8's heap or only need read access.

This means that IsDeadCeck and EnsureInitialized could sometimes be
called without having already entered the VM.  To simplify things,
this is made always the case.  A couple of error callbacks do not need
to leave V8 because they haven't entered.

Consistently enter V8 after LOG_API (since LOG_API is sometimes before
EnsureInitialized or IsDeadCheck).

This all should have no effect unless V8 is built with
ENABLE_HEAP_PROTECTION and run with --protect-heap.

Fix exception propagation problem where undefined was returned instead
of an empty handle in case of an exception.  This problem can break
C++ programs that are not interested in catching exceptions and just
want to propagate them out by testing for empty handles.

The issue is that exceptions are not rescheduled if they are
externally caught.  Externally caught exceptions have to be
rescheduled if there is a JavaScript frame on the way to the C++ frame
that holds the external handler.

A couple of tests will fail on the ARM simulator because the simulator
has separate stacks for C++ and JavaScript.  I have marked the tests
as failing only on the simulator.
