MIPS: [builtins] Unify the various versions of [[Call]] with a Call builtin. (Closed)
DescriptionMIPS: [builtins] Unify the various versions of [[Call]] with a Call builtin.
Port of https://codereview.chromium.org/1311013008/
Original commit message:
The new Call and CallFunction builtins supersede the current
CallFunctionStub (and CallIC magic) and will be the single bottleneck
for all calling, including the currently special Function.prototype.call
and Function.prototype.apply builtins, which had handwritten (and
not fully compliant) versions of CallFunctionStub, and also the
CallIC(s), which where also slightly different.
This also reduces the overhead for API function calls, which is still
unnecessary high, but let's do that step-by-step.
This also fixes a bunch of cases where the implicit ToObject for
sloppy receivers was done in the wrong context (in the caller
context instead of the callee context), which basically meant
that we allowed cross context access to %ObjectPrototype%.
