In terms of C++ testcases, I'm wondering if you already double checked that the new pass already does well on the typical examples on which, I was told, the Microsoft optimization is known to do well, eg, code instantiating std::vector for different pointer types, or even long and long long on x86_64-linux, things like that.

Thanks,
Paolo.
