The Test PLA extends this idea further. It operates asynchronously with respect to the sequencer. After a protection test fires, the PLA needs time to evaluate and produce its redirect address. Instead of stalling, the 386 allows the next three micro-instructions to execute before the redirect takes effect -- and the microcode is carefully written to use these delay slots productively. This is tremendously confusing when reading the microcode for the first time (huge credit to the disassembly work by reenigne). But Intel did it for performance.

This works, but it has a vulnerability: it hardcodes the native code string manually. If fermaw’s integrity check was especially paranoid and compared the spoofed string against the actual native code string retrieved from a trusted reference (say, by calling Function.prototype.toString.call(originalFunction) on a cached copy of the original), the manually crafted string might not match precisely, particularly across different browser versions or platforms where the exact whitespace or formatting of [native code] strings varies slightly.
