gcc now supports this too. So I think this patch should enable it.
It's off by default so you'll have to add --param asan-instrument-allocas=1 into cflags

Thanks, will fix. For now, it looks like I'll need to build gcc from git to test this?

Tests would be better as a separate patch.

I was following the precedent in 828347f8f9a5 ("kasan: support use-after-scope detection") which added both at the same time. But I can split the test off into a separate patch if you feel really strongly about it.
