    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.
