It’s intriguing to me that this is so, given that most of the point of writing native code these days (rather than targeting some managed-native system like the CLR) is to optimize hot loops, and one of the best optimizations for hot loops is to get them to fit entirely into a cache line. Do compilers for C/FORTRAN/etc. not have any mode or pragma to indicate that you’re attempting to get this performance benefit from a given function-and-its-dependencies?
