Details

MOPs support for float4.  The full spec will be in the ABC Extensions Spec dated December 1, 2011 or later.

Scope:

- abcasm
- abcdump
- interpreter
- JIT
- run-time support
- ByteArray storage alignment must be guaranteed to be 16 or better

The storage alignment is required because the C++ compiler and the JIT will want to emit guaranteed-alignment access instructions.  See spec.
Assignee: nobody → lhansen
And also:

 - verifier
 - wordcode translator
Looks like I have all pieces of this working, except for ByteArray alignment and in-line code generation in the JIT.  Those pieces can probably be a follow-on bug.
