Bug 121055 – Change virtual register function arguments and locals from unsigned to int

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Michael Saboff]

This is part of making the change for https://bugs.webkit.org/show_bug.cgi?id=118758 - "fourthTier: Change JSStack to grow from high to low addresses".  In many places the the type of virtual register variables and argument are unsigned.  These should be changed since offsets can be both positive and negative.

I don't think this empty function list is super helpful. Perhaps you could truncate it to a file list.
