> We generally apply dead code elimination implicitly in HOP DAG construction and according
to the data flow analysis of used variables. However, with IPA and rewrites additional branches
and function calls might get removed which sometimes creates additional opportunities for
dead code elimination. Therefore, this task aims to add an IPA pass for dead code removal.
