[appologies if posting too often bothers people, just have a lot to say
at the moment. ]
In doing profile analysies on my code I came across something truly
SmallInteger > bitAnd: was, itself, calling SmallInteger> bitOr: !!!!
I thought "WTF?!?!?!?!"
and went to investigate. The code in interp.c was nearly what I had
expected it to be.
I looked very closely at the code in bitAnd: and came to the conclusion
that the primative implementation was stripping out the sign bit and
that the code in the image was correcting for this with a kludge
I'm probably wrong... What's the real story here?
