Hi Jimmy,

I thght the linker alone was supposed to be able to do dead-procedure-elimination.

No. It is a nice feature, but it is not a requirement of a linker.

After all can't the linker determine which procedures are unreferenced in the final executable?

Which is exactly what the --ffunction-sections and --gc-sections switches do.

If i'm not mistaken the diablo linker can do this?

It probably can.

Cheers
  Nick
