-O3 option question

-O3 option question

hi all,
Is there any option switch to control -O3 level optimizaion,for example,if I don't want to perform loop interchange but icc does it,also I want to set the loop blocking size by myself,is there any option switch I can use? I've read many documents but found nothing. thanks.
