Yeah originally I was going to do that, but:
1. We had a stack use-after-return last month that people had to debug by
hand. that would have been caught by ASan with stack-use-after-return. So
it seems like a worthwhile feature to support.
2. Initially I was concerned about code size and one thing I was planning
to do was to disable stack-use-after-return instrumentation. But in
practice, we find that this was a non-issue: we are able to run the same
number of tests with and without such instrumentation.
3. It seems like a good idea to keep the same default behavior and feature
parity with x86 ASan when possible.
Thanks,
Walter
