#[non_exhaustive]pub enum RegallocAlgorithm {
Backtracking,
}
Expand description
Possible register allocator algorithms for the Cranelift codegen backend.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Backtracking
Generates the fastest possible code, but may take longer.
This algorithm performs “backtracking”, which means that it may undo its earlier work and retry as it discovers conflicts. This results in better register utilization, producing fewer spills and moves, but can cause super-linear compile runtime.
