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.
