On rereading i thought I probably wasnt very clear.
to restate, I was wondering if I can use the selection dag
infrastructure to build def use information. I am looking to use
information such as def-use within a basic block, is the register
used outside the basic block and load/store dependencies.
Any thoughts on doing it before register allocation?
I will appreciate any ideas !
