Marc Glisse <marc.gli...@inria.fr> writes: That's for the alloca case. Without alloca, one call to malloc is better than two (although that usually also means the numbers are big and any gmp operation will dwarf allocation). Also, the threshold between alloca and malloc is quite high, and with many separate allocations that all barely fit below this threshold, the total amount of stack memory used can become too large for some applications (lowering the threshold may be easier than allocating things in groups though). I don't buy this argument.
If the threshold is high, then surely the malloc time will not take a significant fraction of the total time. If the threshold is too high, then we should lower it. Is there no good range for the threshold? Show me the numbers...! -- Torbjörn _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org http://gmplib.org/mailman/listinfo/gmp-devel
