--- Comment #193 from Don Lewis <[email protected]> --- (In reply to rozhuk.im from comment #190) I don't see that change in the March 2017 AMD64 Architecture Programmer’s Manual Volume 2: System Programming (revision 3.28), which I found here: http://support.amd.com/TechDocs/24593.pdf The only change to the #UD description is the addition of the UD0 and UD1 instructions as potential causes. I didn't find these in the AMD documentation, but apparently they are reserved opcodes that will generate #UD. It looks to me like encountering this bug will kill the process with SIGILL, which we aren't seeing. Working around this looks like it would be ugly ... -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
