enableNarrowingCastToSliceTransform

bool P4::StrengthReductionPolicy::enableNarrowingCastToSliceTransform = false

Replace narrowing casts with slices. i.e. replaces (bit<n>)(expr) with expr[n-1:0] when n is smaller than the width of expr.

enableSubConstToAddTransform

bool P4::StrengthReductionPolicy::enableSubConstToAddTransform = true

Enable the subtract constant to add negative constant transform. Replaces a - constant with a + (-constant).
