COL7529 HW 4 : SSA conversion in LLVM

Due date - 23:55, 25 Oct 2026

Weightage: 20 Marks (Actual weightage, We will decide later)

We have discussed SSA conversion in class, and discussed minimal and pruned-SSA forms of the program. Answer the following question, and submit a short report:

• Does LLVM use pruned SSA? Use an example C program foo.c, and compile it using the following command to demonstrate the presence or absence of a Phi-node to justify your answer.

  clang -O1 -S -emit-llvm foo.c -o -
