Is it possible to dynamically switch between the two? The two cases I'm thinking of are: 1) Using the interpreter to execute one or two instructions in an exception handling case 2) Avoiding TCG code generation on the first few runs of a piece of code that might only be init code, and only bothering with TCG for hotter code.
