Enum CompilerPassOrder 

pub enum CompilerPassOrder {
    CanonicalOrder,
    InlineFirst,
    AggressiveFold,
    Custom(Vec<CompilerPassId>),
}

Canonical ordering in which passes are applied during one outer iteration.

Variants

CanonicalOrder

ConstProp → DCE → Inline → Algebraic → Rewrite

The default, well-balanced ordering. Constant folding and DCE simplify the tree before inlining; algebraic passes follow; pattern rewrites last.

InlineFirst

Inline → ConstProp → DCE → Algebraic → Rewrite

Inlining first exposes more constant sub-expressions for subsequent folding and elimination passes.

AggressiveFold

ConstProp → ConstProp → DCE → Inline → ConstProp → DCE → Rewrite

Runs constant propagation twice before elimination, then once more after inlining to catch any newly-exposed constants. Useful for deep algebraic expressions with many nested constants.

Custom(Vec<CompilerPassId>)

User-supplied pass sequence.
