I would like to have access to def-use relationships at O0 , for now
after register allocation. So my question is
1. is there any such existing information ? If not, do i need to build it
from scratch by traversing all the instructions and operands ?
2. While for now I only need it Post RA but eventually I want to use it
before RA as well. Suggestions on how i can go abt that would help me reuse
code/def-use data would be great !
thanks for all help !
