I've used IDA Pro quite a bit and like it a lot.   One of things that it
does is analyze program flow.  You can assign your own labels and symbol
names; it can detect subroutine boundaries and you can change the
assembly syntax of constants.

Disassembly is never lots of fun, but IDA makes it easier.  I think that
it's still possible to get the old "free" version on the web.   The "pay
to play" version covers a lot of processors (8- 16- 32- and 64-bit).

IDA does require a bit of learning the lay of the land, but once you et
started, things get easier faster.
