Vlad, I noticed that the code in setup_cover_and_important_classes in
ira.c does #ifdef CONSTRAINT__LIMIT. However, CONSTRAINT__LIMIT is not
a preprocessor macro; it is an enum constant defined in the generated
file tm-preds.h. I think that the code within the #ifdef is either
unnecessary or is not running when it should. I haven't investigated
further.
Ian, thanks for reporting this. I'll investigate this more. It
affects only ports using priority allocation (I know only one which is
m32c). DJ just recently reported a reload failure problem on m32c.
Probably that is because of this wrong code.
