Author: kib Date: Fri Jan 7 14:35:45 2011 New Revision: 217101 URL: http://svn.freebsd.org/changeset/base/217101 Log: On amd64 and i386, force assembler to mark objects compiled from the assembler source for libcompiler_rt as not needed executable stack. This is done with a hammer instead of properly marking each assembly file with section .note.GNU-stack to avoid modifying contributed source.
