Hello,
I have a PHI node that defines a variable that is used in 1 statement. I then delete the statement. I think I need to update the PHI node to no longer reference that variable. I looked through some code and I don't see a way to just remove an element from a PHI node and I see in the file omp-expand.c what looks like creating a new PHI node and copying over all of the elements. My question is: how do I update a PHI node per the above? Is it necessary - if I don't do anything and leave the PHI node as is it appears to work, though I don't know the implications of this. If I do need to update it, do I recreate it and delete the old one? Thanks and Regards, Shubham
