Can you give more specifics? Backend-wise, the new asm support is still using LLVM's assembly facilities, so it should be just as capable. As far as the user-facing portion is concerned, some features of the `asm!` macro are still unstable (most notably const operands and sym operands), but I'm not aware of any feature that doesn't have an equivalent.

Unfortunately, I no longer remember my old example, and I wasn't able to find a good new example. So maybe it is as powerful now.
