6 Most of the time we think of JiTs jumping to the entry of a function, but if you’re stuck in a hot loop then you can’t do that. This is where OSR comes in. OSR effectively turns a function “inside speculative reordering of loads and stores. x86 instructions are initially interpreted, and if deemed “hot” they’re JiT-compiled in a hidden part of the hardware, effectively ring -1. I don’t know about you
