We should consider removing support for low end Pentium as well. I'm specifically thinking of removing the workarounds like F00F. Are there any processors that are still vulnerable to this? We have only removed support for 386 since it didn't support cmpxchg. We still nominally support 486s. I don't know how well FreeBSD 13 would run on a 486, but in theory the code is still there and the binaries shouldn't die with illegal instruction faults. -- John BaldwinReceived on Thu Feb 28 2019 - 18:44:52 UTC
