https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221029 --- Comment #50 from Don Lewis <truckman@FreeBSD.org> --- (In reply to Conrad Meyer from comment #48) Interesting link. I've been hearing rumors about this, but this is the first detailed info that I've seen. Speculative execution is one of the things that came to mind with the signal trampoline issue. In this case, I would think that speculative execution would not get past the ret instruction. -- You are receiving this mail because: You are the assignee for the bug.
