Hi,
I have read ira/lra code for a while, but still fails to understand
their relationship. The main question is why ira do color so early?
lra pass will do the assignment anyway. Sorry if I mess up coloring
and hard register assignment, but I think it's better to get job
done after lra elimiation, inheriation, ...
Any professional can help me out? Thanks.
