Yes, that's part of what was done here. So, create a plan, and then for some subset of plans, create AOT-compiled templates. The analogies are: a) original implementation is like interpreting via walking a syntax tree b) building/caching an execution plan is like interpreting by executing bytecode generated from the syntax tree c) using an AOT-compiled template is like execution from qemu's old TCG template system But we only do (c) for a popular subset of function signatures. The biggest win was (b), but (c) is still an improvement over (b).
