I've noticed quadratic (or worse) compile speed, too. I have a hairy
case of only 1000 lines that takes around 5sec to compile; it includes a
700-line @load sub with 450+ $Pxx variables. It goes around the
compute_spilling_costs / order_spilling loop in imc_reg_alloc some 120
times before it decides it's done, but I didn't have the time to look
farther. (r8203.)
Believe me, speeding up compile times would make Dan a Happy Camper(tm) :)
