Rather... but ld, C, Unix... it's a little the same area (hum...)

Interesting! Do you know how it works ? By simulating execution and
``colouring'' used code ? Does it trim unused global variables
or constants too ? Can it replace ld ?

It would be interesting to know if such a low-level trimming is safe.
E.g. can it detect tricky code address calculations (ASM/C-like)
that would make an apparently unused code section used indeed ?
