pub struct InsertBuilder<'f, IIB: InstInserterBase<'f>> { /* private fields */ }
Expand description

Builder that inserts an instruction at the current position.

An InsertBuilder is a wrapper for an InstInserterBase that turns it into an instruction builder with some additional facilities for creating instructions that reuse existing values as their results.

Implementations

Create a new builder which inserts instructions at pos. The dfg and pos.layout references should be from the same Function.

Reuse result values in reuse.

Convert this builder into one that will reuse the provided result values instead of allocating new ones. The provided values for reuse must not be attached to anything. Any missing result values will be allocated as normal.

The reuse argument is expected to be an array of Option<Value>.

Reuse a single result value.

Convert this into a builder that will reuse v as the single result value. The reused result value v must not be attached to anything.

This method should only be used when building an instruction with exactly one result. Use with_results() for the more general case.
