[gnu.gcc] gcc Internals question for port to 3B2

rgoguen@bbn.com (Robert J Goguen) (11/30/88)

	In the gcc internals document the I have a question in the section
 "Standard Names for Patterns Used in Generation". 

	When you describe the insv instruction you state that operand 2 is the
starting bit. Now if operand 2 == 3 does this mean that I start

	7 6 5 4 3 2 1 0
		^
		|
		|

or do I start

	7 6 5 4 3 2 1 0
		  ^
		  |
		  |

The same question goes for the extv pattern and operand 3.


	Thanks
