1234738 - Emit ALIASEDVAR ops for block-scoped lexicals at top level

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Shu-yu Guo [:shu]]

Currently we emit NAME ops for lexicals at blocks at global level, e.g.:

{
  let x;
  function f() { x; /* emitted as GETNAME "x" */ }
}

Attachment: Emit ALIASEDVAR ops or block-scoped lexicals right below global level.

How should we test this?
