From what I've read, Fortran's performance advantage over C is mainly due to a lack of pointer aliasing[1] which permits the compiler to optimize more aggressively. I am curious to know if modern Fortran compilers still use static allocation for local variables when compiling in Fortran 77 mode. I'd guess the cache advantages of keeping parameters close together in memory compensates for the extra work of manipulating the stack, but who knows...
