Issue hasn't been assigned a status value.

Can there be a flag/setting for DM to throw warnings whenever it detects completely unused/dead procs? It would help with optimizing certain projects heavily as currently those functions are still compiled into the final dmb.

It could be implemented the same way DEBUG is implemented, as a flag in the .dme
#define WARN_UNUSED_PROCS

or as a compiler flag, like -wunused-proc

Zewaka	the problem is you can call procs dynamically

Spevacus	Personally, if this was implemented and I turned it on in a project and I had a proc that I only called dynamically, I'd be fine seeing a warning that it's unused. I can't expect the compiler to be smart enough to know that I'm calling a proc dynamically.

I can't expect the compiler to be smart enough to know that I'm calling a proc dynamically. I could expect it for trivial cases where you're not doing runtime string-building of the proc name.
