Hi,
In 1364-2001 LRM, it was mentioned:
If any bit of the genvar ever is set to an X or Z or if the genvar is set to a negative value,this shall be an error.

In 1364-2005 LRM, it is mentioned:
It shall be an error if any bit of the genvar is set to x or z during the evaluation of the loop generate scheme.

So is now negative value allowed to be assigned to genvar? Is the change intentional?
