            Bug ID: 48552
           Summary: sext .. to instruction inconsistency with i16
           Product: new-bugs
           Version: 11.0
          Hardware: Macintosh
                OS: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

When using the 'sext' instruction with a destination type of i16, the resulting
value is unsigned. 

For example:

%X = sext i8  -1 to i16              ; yields i16   :65535

Whereas 

%X = sext i8  -1 to i32              ; yields i32   :-1
