Configuration for the constant propagation pass.

Fields

fold_arithmetic: bool

Fold arithmetic binary operations when both operands are constants.

fold_comparisons: bool

Fold comparison operations when both operands are constants.

fold_boolean: bool

Fold unary operations (Abs, Floor, Ceil, Round, Sqrt, Exp, Log, Sin, Cos, Tan, Not) on constants.

max_passes: u32

Maximum number of convergence passes to perform.

float_tolerance: f64

Absolute tolerance used when comparing floats for equality (Eq comparison).
