Loop Transformations

The loop transformation techniques include:

• Loop normalization

• Loop reversal

• Loop interchange and permutation

• Loop distribution

• Loop fusion

• Scalar replacement

• Absence of loop-carried memory dependency with the IVDEP directive

• Runtime data dependencies checking (Itanium®-based systems only)

The loop transformation techniques also include:

• Induction variable elimination

• Constant propagation

• Copy propagation

• Forward substitution

• Dead code elimination
