BTW, here I have a patch that brings our copy of dtrace dis_tables.c to the latest version available in OpenSolaris code: http://people.freebsd.org/~avg/dtrace-disassm-osol.diff I haven't studied at all what the newer code brings in, but it must be some fixes and improvements, I guess :-) The change is mostly a mechanical merge, plus some changes on top to get the code to compile. I've been using the code for a few weeks and haven't run into any problems. Should I put this change into the tree? -- Andriy Gapon _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
