On: From 60 Frames per Second to 500 in Haskell

But is that data that ends up in the lib*.so's?

I can see that possibly optimizing within GCC (or LLVM if it supports it) but I have no clue for library shared/static objects.

The annotation would go in the header files, so that it works with lib*.so's. For example, glibc's strlen is marked this way (as well as a whole host of other functions).
