If you look at the pre-FPO example for MyFunction, you'd notice that the first instruction in the routine was PUSH EBP followed by a MOV EBP, ESP.

Possibly the favorite XSLT 1.0 instruction is XSL: value-of, which can be used to push a value onto the output as a string.

This instruction is not using any bytecode fetcher because it doesn't need to JMP to another handler. I will now present a real instruction. A Virtual PUSH.
