Well it was a hot take.

Are you unaware that you can write code to RW memory, remap it to RX and then run it? That's how all JIT works these days.

(Or did you confuse cache flushing with TLB flushing? The remap does the latter, not the former.)

		Yeah, that works okay, but really is a you shouldn't, with pipelining you lose all the predictive decoding. The Synthesis kernel did some cool ass shit with this, but failed in other architectures due to pipelining, which speeds up shit, but change the opcodes(with other instructions(ie selfmodyfing code)) and shit gets flushed.
