I am curious about the following concerning your "average" compiled (or
even assembled) code:

1)  What is the density of conditional branch instructions?
2)  How often does a branch actually occur?
3)  What is the density of unconditional branches?
4)  What is the density of subroutine calls?
5)  What is the average distance that an unconditional branch "jumps"?

These questions seem relevant to instruction cache issues.
