...on with *IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS* <ioctl_volume_get_volume_disk_extents.htm>. This control code returns the disk number of offset for each of the volume's extents; a volume can span disks." It is disknumber, no devicenumber. Pls fix it.

Ok, let‘s stop the open64 "polution". Whether the design is as you stated doesn‘t simpler, the code before and after the change already tells us. We take detailed investigation on gcc support for hwloop, then we come to the conclusion we are essentially the same. So i think the idea can be shared among different compilers, general abstract tripcount, make pseudo operators for

Hi shuxin, Promote while-loop to do-loop is the job of loop induction recognized, not this transformation. The scalar transform for hwloop in optimizer is for that it is a trouble to discriminate trip counting code with the real production code stuff and do the elimination in cg, we have to write customized code to handle this general stuff in ervey targets. So, we take the help from optimizer

I am the designer for open64 hwloop structure, but I am not a student. Hope the following helps: To transform a loop into hwloop, we need the help from optimizer. For example, while(k3>=10){ sum+=k1; k3 --; } into the form: zdl_loop(k3-9) { sum+=k1; } So, we introduce a new ZDLBR whirl(open64 optimizer intermediate) operator, which represents the loop in whirl as:
