[llvm-dev] ASan port for Myriad RTEMS

[Jake Ehrlich via llvm-dev]

Eh...there isn't a good place to know whats happening but I can keep you
apprised of major updates. For the golang prototype you can check for
commits here: https://fuchsia.googlesource.com/tools/+/master. Once we
start on the LLVM part we'd need reviewers so you could stay apprised by
reviewing my code ;)
