Re: [RFC] Internal operator overloading and GMP improvements

Hi Nikita, Few final notes: - I wouldn't change zend_object_compare_t into zend_object_compare_objects_t. It would be better to name the new function as zend_object_compare_zvals_t. (It's just for better backward compatibility) - Increment and decrement operators in PHP may have different semantic than +=1, but I it's probably OK to use ADD/SUB for them. - In some cases you insert call to zend_object_do_operation into the most probable path (e.g. in mod_function). This would cause at lease 2 additional comparisons and may be conditional jumps. I think it would be better to check for most probable operand types first... I didn't look into GMP part. Thanks. Dmitry.
