You enabled front-end inlining with -gnatN; GNAT turned the whole
program into one procedure. Even then, it should be possible to run
the program under valgrind's callgrind tool to get accurate, per-line
(indeed per-instruction) execution costs. I don't know whether gprof
has such granularity or not.
