Certainly older compilers did tend to have canned blocks of code that were brought in fairly predictably to implement language-specific patterns. But as you say, optimization tends to hide that, and perhaps even more so does the use of common compiler middle and back ends, to use GCC terminology. Perhaps the OP can tell us which FORTRAN compiler was used (should be easily identifiable from IDRs).
