chunyang.dai 99f0130782 X87: [calls] Consistent call protocol for calls. 
port b37907ff7f (r30648).

original commit message:

    The number of actual arguments should always be available, there's no
    point in trying to optimize away a simple assignment of an immediate to
    a register before some calls.

    The main motivation is to have a consistent state at the beginning of every
    function. Currently the arguments register (i.e. rax or eax) either contains
    the number of arguments or some random garbage depending on whether
    the callsite decided that the callee might need the information or not.
    This causes trouble with runtime implementations of functions that
    do not set internal_formal_parameter_count to the DontAdaptArguments
    sentinel (we don't have any of those yet), but also makes it impossible
    to sanity check the arguments in the callee, because the callee doesn't
    know whether the caller decided to pass the number of arguments or
    random garbage.

V8 JavaScript Engine

V8 is Google's open source JavaScript engine.

V8 implements ECMAScript as specified in ECMA-262.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 can run standalone, or can be embedded into any C++ application.

V8 Project page: https://code.google.com/p/v8/

Getting the Code

Checkout depot tools, and run

    fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
