Hi Andrew,

IMO is not worth compiling almost 1500 files for really using just a few
of them.  Also the compilation is realtivelly quick (~0.2s each on my
machine), I guess the most is GCC/GAS startup time.  Indeed this time is
payed only once when the primitive is redefined the first time.

That said if you want to experiment I think something like this should
do the job:

(mapatoms (λ (s)    
            (when (subr-primitive-p (symbol-function s))
              (comp-trampoline-compile s))))

Ciao!

  Andrea
