[M3commit] CVS Update: cm3

[Jay K]

Tony there are multiple related problems here.

 

1) The front end likes to output values between 128 and 256 with type Int8 instead of Word8.

  e.g. in InitTypecell.

  And maybe similar for 16/32/64, I don't know.

 

2) Even if the front end used the correct Word8 for them, m3back needs to use TWord.ToBytes vs. TInt.ToBytes for unsigned types, but TWord.ToBytes doesn't exist.

 

I'll see what I can do.

I'll probably add TWord.ToBytes and if the value fits using it, accept it.
