Method replace_redundant_loads

cranelift/codegen/src/context.rs:348–352

Replace all redundant loads with the known values in memory. These are loads whose values were already loaded by other loads earlier, as well as loads whose values were stored by a store instruction to the same instruction (so-called "store-to-load forwarding").

    /// by a store instruction to the same instruction (so-called

        analysis.compute_and_update_aliases(&mut self.func);
        Ok(())
    }
