RE: [GD-General] remove unused functions

[Tom F. <to...@mu...>]

Maybe you can add a prologue to every function that does two things:

(a) declares a static instance of a class whose constructor adds the string
"__FILE__ __LINE__" to a table.

(b) when it is called, finds and removes the string from the table.


Play the game for a while, go through as many different codepaths and
behaviours as you can think of, then dump the table to disk or whatever. And
there you go - a list of all the functions (well, where they are - maybe
there's a MS #define that lists the function name?) that haven't been called
this time around.

Then add ASSERT (!"Nobody ever calls me or they would have removed this
assert") to each file, leave it a couple of weeks, and then kill all the
functions that still have that assert.
