Report by the President of RA I Dr. Lamine BAH Cg – XVI / Doc. 2.4 Geneva, 2011.
Components of representation Control dependencies: sequencing of operations –evaluation of if & then –side-effects of statements occur in right order Data.
1 CS 201 Compiler Construction Lecture 7 Code Optimizations: Partial Redundancy Elimination.
1 Data flow analysis Goal : collect information about how a procedure manipulates its data This information is used in various optimizations For example,
Recap from last time We were trying to do Common Subexpression Elimination Compute expressions that are available at each program point.
Class canceled next Tuesday. Recap: Components of IR Control dependencies: sequencing of operations –evaluation of if & then –side-effects of statements.
Dataflow Analysis Topic today Data flow analysis: Section 3 of Representation and Analysis Paper (Section 3) NOTE we finished through slide 30 on Friday.
1 Data Flow Analysis Data flow analysis is used to collect information about the flow of data values across basic blocks. Dominator analysis collected.
