I have ported ASan in LLVM to Myriad RTEMS, and I would like to
upstream the port.  Below is the design doc.  Feedback welcome.


The port is expected to work with modified versions of RTEMS and
newlib.  I have a git repo with changes to those projects, that I can
make available if there is interest.
