[AVR] Fix def state of operands

Authored by aykevl on Feb 21 2021, 11:28 AM.



Some instructions (especially mov+pop instructions) were setting the wrong operands. For example, the pop instruction had the register set as a source operand while it is a destination operand (the value is loaded into the register).

I have found these issues using the machine verifier and using manual code inspection.

Fix this lint warning.

Thank you for the review!


I intentionally kept it as-is, to match the existing code. See the golden rule:

If you are extending, enhancing, or bug fixing already implemented code, use the style that is already being used so that the source is uniform and easy to follow.
