is SCHED_FIFO or SCHED_RR or the newer incarnations viable? Is it possible to make QEMU deterministic? a quick glance at the realtime schedulers state source code needs to take that into consideration.
I know it seems like i don't know what i am talking about, often, on here. The reason is i don't live on HN so i type a comment and rarely remember the words i want to use before the edit/delete window closes.
The idea that i can't control when things occur during a compilation seems suspect. Is there a certain "code size" or other bellwether where this non-determinism starts to crop up? I ask because i get the feeling if i start compiling trivial stuff it will all be bit-perfect and if i say so i'll get lambasted for "well obviously trivial stuff can be reproducible," so i am heading that off at the pass, first.
