Looking around shows "ISO/IEC JTC1 SC22 WG21 N2745" was revised to say: "Finally, applications that need to use C/C++ sequentially consistent atomic operations on Power 5/5+ must adhere to the rules set out separately." with those rules being listed separately in: http://www.rdrop.com/users/paulmck/scalability/paper/N2745rP5.2010.02.19a.html Looks like power5/5+ was a bit of an odd ball compared to the others. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
