Just to let you know, I'm still investigating a solution.
Ok. I would prefer if a seperate PR is opened for the REG_EQUAL
problem, since that is a generic compiler issue actually.
I wonder how hard it would be to just create a dummy:
(set DEST CONTENTS_OF_REG_EQUAL_NOTE)
when such a note is present and then use that for the transformations
in combine or whatever.
