Inside sqlite3VdbeExec there is a very big switch statement.
In order to increase performance with few modifications to the
original code, why not use this technique ?
http://docs.freebsd.org/info/gcc/gcc.info.Labels_as_Values.html

With a properly defined "instructions" array, instead of the switch
statement you can use something like:
goto * instructions[pOp->opcode];

I said: "Aujourd'hui!"
